Subject: [linux-audio-dev] Canorus 0.0.2 released
Message-ID: <44F7C6C7.5090102@web.de>

Hi,

Canorus, the successor to the music score editor NoteEdit is looking
for developers wanting to join the project. The project is hosted on
berlios and provides SVN access to the sources as well as a Wiki for
project discussions.

I put out a first release based on the current SVN. You can fetch it
from http://prdownload.berlios.de/canorus/canorus-0.0.2.tar.bz2.

Homepage:  http://canorus.berlios.de
Wiki:             http://canorus.berlios.de/wiki/index.php/Main_Page
Contact:       http://canorus.berlios.de/contact.html

Canorus is the next generation music score editor (multiple viewports
of the same score, scripting support, score source view, fast and
intuitive UI, free software and cross-platform) . Technically it is
based on Qt4, uses CMake as project management tool, swig for scripting
/ macros integration (primary script languages are ruby and python) and
the cross platform rtmidi library for the MIDI playback.

Canorus is searching for developers with experience in the fields C++,
Ruby, Qt4, XML, Parsing, User Interfaces, Music Composition and Theory,
Translators, Score Editing Unit Tests.

Some of the tasks are:
- Add several UI parts (either via Ruby or in the core) like Settings,
several different property perspectives, Lyrics, Import / Export
- Development of a robust test engine for the user interface and
its core (could be done via scripting)
- Import parsers for ABC Music, Lilypond, MusicXML, MUP (& NoteEdit),
MusiXTeX, PMX, MIDI etc.
- Export for several formats like the above
- Recording and replay of macros
- Multi-Level Undo/Redo (for different perspectives)

If you want to join the project  just mail me your berlios unix name
(user name you use to log into berlios). I'd use that name for a wiki
account too and will send you a password you should change as soon
as possible.

A big "thank you!" to everyone making this project possible.

Best regards,

Reinhard Katzmann

Surprising to see this Wine ASIO/Jack driver is actually quite  
similar to the ASIO/Jack driver I did to allow ASIO Windows  
applications use Jack in the Jackdmp windows 32 version...

Something is probably wrong in the code: the  jack callback process  
samples only if transport is rolling. I think this is incorrect.

It might be wise to forward this info to the Wine list as TTBOMK they are
currently not a member of the consortium or the lau/lad community.

It is part of a Qtopia Development Kit, and is not targeted at consumers and 
is in limited supply, so don't expect a normal consumer mass market price 
point.
It will be affordable, but not cheap.

The hardware support is in various states of working, but we will provide 
updates as it improves.

Message-ID: <44FAD215.9030408@woh.rr.com>

Greetings:

I've been adding some logos to the top page at linux-sound.org, and I 
thought it might be time to make some remarks regarding them.

Some are nice, some are very cool, and some are pretty awful. The logo 
for LilyPond really needs an update, and where is Ardour's bitchin' cool 
logo ? Some need titles (IMO), such as Aeolus, Common Music, LilyPond, 
ChucK, Dino, and Khagan. I'm not a graphic artist, and I'm not going to 
go through the process of overlaying titles. If the devs for those apps 
are happy with the logos, that's perfectly cool by me, but IMO it's 
better to have a title.

Some other logos are in need of an update, e.g. PlanetCCRMA, LAU, and 
RTcmix. Is Thorsten our only graphic artist, or does anyone else here 
have good graphics skills ?

I'm sure I'm missing logos for other apps. If you have an application 
listed on linux-sound.org, please contact me if you'd like to add a logo 
to the top page.

Best,

dp

/me adds Khagan banner on todo. Proirity will increase, if Loki gets 
back to coding ;)

I'm going to redo the LAD/LAU one for lad.linuxaudio.org, anyway.


The Gungirl banner freaks me out!

That page could look much better with same height for all ...
but yeah, I know it's unlikely to happen :)

I think it would be nice if we got someone "commissioned" to make consistent
set of icons (and subsequently logos) for most prominent audio apps (and
ultimately all which are in a need of this). Naturally, funds are a touchy
subject in this case, but if someone with drawing skills is interested in
this I think it would be to a great benefit of the entire community.

Best wishes,

Message-ID: <20060904194323.GC14448@jdboyd>

It appears to have been more than a year since the company was mentioned
at all.

Has anyone ever tried contacting them about specs to write drivers for
newer devices than the ones listed on their developer page?
http://developers.marian.de/

Specifically, say the Trace D4 cards?  It looks like the newer cards
like the Trace D4 use a FPGA for everything rather than some sort of
programable logic attached to a PLX PCI interface chip, which I'm
guessing means that their legacy documentation bears little relevence to
their current cards.

They do invite people to contact them about information not found there.

One appealing aspect of their products is they allow hardware syncing of
different cards (which M-Audio also does), and they have a wide variety
of card types (all analog, all digital AES, ADAT, with or without midi,
etc).

Now THAT would be distasteful. ;-)

I believe they just need someone to write the drivers....

they did not seem completely against Linux, when I talked to them on the AES

Probably not. And you need not only the driver, but also a
dedicated mixed app similar to hdspmixer. If I would be a
bit more familiar with USB and how things USB are done in
Linux, I'd probably be prepared to write a JACK backend for
this device. It's a 'pro' device anyway, so I wonder if an
ALSA driver is worth the effort.

many companies count input + output separately. RME, for example.

It's 16x16 = 8x8 analog + 8x8 ADAT optical

Unfortunately I've been involved with audio for long enough that
I keep getting confused by this modern marketing technique,
eg. the `24 channel mixing desk' with only 8 mic inputs or
the `64 track studio' with only 16 hardware inputs ;)

They have already released specs for some older cards.  I wonder how
they feel about people desiring to write drivers for linux when the
older cards never had support added?

At this point the older cards are kinda pricy though.  I believe it
would cost me less to buy a Delta 44 than it would to buy the equivelent
Marian card, and I suspect the Delta44 is a bit nicer.  But people in
Europe might find the pricing different.

PS, if anyone wants to send me (or sell me a used one for well under
retail pricing) a Marc 2 or 4 of the sort that specs are
posted for, I'd be happy to write an alsa driver for it.  I have
experience writing linux drivers for other hardware under NDA.  If
someone did this, once I had the Marc driver done, I'd be happy to try
to approach Marian about UCON information.

Another important question, are they willing to comply with the GPL?
Many companies seem to believe it's legal to develop a closed source
driver for Linux...

Is it not legal?  

I know the license for the linux kernel provides (last time I looked) an
exception -- the intent of which was to allow porting of existing
drivers/filesystems, etc, from other unices to linux -- which would
clearly not be derived works.  And there are the GPL_ONLY symbols and
such... sort of implying the symbols which are not GPL_ONLY are
fair game for binary-only drivers.  And there are some binary-only
storage drivers I know of -- cheap SATA software RAID and such usually --
I seem to recall the video guys are perhaps the worst offenders
in terms of pushing binary-only drivefs, I guess that's still true.

Just saying, judging by the current state of affairs -- loads of existing
and current binary-only drivers for linux floating around for brand new
hardware unhampered by litigation -- if it's not legal, it might as well
be.  Without saying too much, I have some interest in this beyond just
conversation.  To clarify my position, I do think binary-only drivers suck,
and I would be the first to advise people not to buy, e.g. esp. storage
solutions which rely on binary-only HBA drivers, and I advocate so much
as I am able within the company which employs me to avoid such things.
But to say they are not legal is pretty strong, in view of the extant 
binary-only drivers floating around.  If they really are illegal, then 
I'd want to know that.  If it is so, it seems not to be enforced at all.

Oh, yeah, IANAL, of course, and consequently I stupidly attempt to apply
rational thinking to licenses and such.  Programmers and lawyers mixed
together is a recipe for insanity.

Hi!

Finaly I'm done with my redesign of http://lad.linuxaudio.org

My first aim was fast and easy access to suscription and archives.

Contents of the Contrib directory are now under events. With the 
exception of 2003_practical-linux, which I don't know what to 
do with (bunch of xml slides?).

Kicked all PHP and took care of validating XHTML 1.0 Strict.

History and Credits are now combined. Would be good if those 
who remember check the text.

I hope the new version of the LAD logo is ok :)
Plan to add a download section also containing the old one 
later on.


Open for all suggestions, remarks and criticism :)

The website indicates it's basically a rewrite of NoteEdit from
scratch, and started by several developers who inherited NoteEdit.

Hi Thorsten,

The new skin is cool. Nice work.

A couple of things I noticed.

1: ressources - should be resources
2: resources->links page = 404

Also we should probably create a webring for all the projects hosted at 
lao...


Cheers.

That, and also a main portal page that clearly lists all subpages which is
something we should probably make a subdomain for (i.e.
portal.linuxaudio.org or something similar).

Webring I don't know, but a portal like Ico mentions is a good idea.

With webring I associate a bunch of sites spread across the net, 
each allowing you to jump to next/previous or go to an overview.

For us, it should just be about a common link to the portal, I think.

Either way we need a way to allow users to easily navigate the whole

Since it's a USB device, I wonder if it's USB "standards-compliant".
Given there is no OSX driver either, the answer might be be no in which
case the driver would pretty much have to written from scratch and
could not be reused.

Full use of the device would require more bandwidth than standards
compliant devices can do usually.

Although, I would how hard it would be to build a device that uses 8
standards compliant USB chips connected to build in USB2.0 high speed
bridges connected to a built in hub.  So, who wants to build this?

Well, for me, the fact that there is no osx driver may well be an indication 
that the producti *is* standards compiant ;)

It is not standards compliant with the usb-audio standard. It will not
work with the snd-usb-audio driver. I had the chance to test this in
the music-shop in Cologne, where the shop keepers were very nice and
let me connect both the UCON CX and the Edirol UA101, to see what
would come up under Linux.

It shows up as a Vendor Specific device, which means they came up with
their own protocol to communicate the audio data via USB.

Message-ID: <ffda12330609171422r67adc6d9jcc89a67d4955e1ee@mail.gmail.com>

Hi there!

I am in the process of adding preset management to my project FLAM
(custom GUIs for LADSPAs, flam.sf.net) which, by the way, is already
running under Rosegarden, checkout the SVN repo if you want to give it
a try.

For those interested I include below the specifications I have came up
with regarding preset management.

First I toyed with the idea of using SQLite to store the presets, but
there were some drawbacks to it (adding an extra dependency,
difficulties to manage list order, etc.) I was driven to it by the
wish of providing concurrent access from different instances of FLAM
but, in the end, I decided this feature was not worth the effort and
downgraded it to the possibility of reloading the preset list to get
the most up to date version at a certain point.

Then I gave a look at the preset API provided by lrdf but I don't like
it very much (makes use of uids -for retrieving the presets and for
avoiding triplet conflicts-, resulting file difficult to read by a
person.) OTOH it is somehow a standard (i.e., ardour uses it, any
other app?)

I have also thought of RDF/turtle as per the new LV2 spec but, if I am
not mistaken, raptor doesn't write turtle and, to be honest, all this
subject/predicate/object/ontology stuff seems like a bit of overkill
just to store groups of (int, float) pairs, although this may change
in LV2 if float is not the only type supported anymore.

Another thing I find awkward regarding preset management is that all
kind of ports share a common index space, so you have to pick the
input control ones among them. This makes the programmer resort to
convoluted data structures for what could be expressed, after all,
with just an array. Not really a big deal, but having the list of
input control ports singled out would make preset management easier.

I would be grateful for any advice on this subject.

Cheers,

Luis


---------------------------------------------------------------------
- Presets management interface:
---------------------------------------------------------------------

- Keyboard accelerators: Ctrl+[0-9] loads one of the first ten
presets in the list (1-based, Ctrl+0 loads item #10.) Ctrl+Shift+[0-9]
saves the current status of the plugin in the corresponding position
of the list (optional confirmation dialog.)
- Context menu: there is a Preset entry in the context menu with three
submenus: "preset manager," "load" and "save." "Load" and "save" unfold
a list of the available presets to load or save respectively. "Preset
manager" opens or brings to front the preset manager.
- Preset manager is a non-modal dialog that displays a list of the
available presets and the following buttons:
    - "Save list" dumps the preset list to the default disk location.
    - "Reload list" reloads the preset list from the default list
    location. Useful to share changes created in other instances of
    that FLAM.
    - "Export" exports the selected preset(s) to a user chosen file
    in a certain exchange format.
    - "Import" imports (adds) to the list the presets stored at user
    chosen file in a certain exchange format.
    - "Apply/Load/Retrieve/Set/Restore?" sets the plugin ports to the
    values stored in the preset (accelerator: doubleclick on the list.)
    - "Store/Save/Overwrite?" saves the status of the plugin to the
    selected preset (optional confirmation dialog.)
    - "New" creates a new preset from the current status of the plugin
    with a default name and enters immediately into rename mode.
    - "Delete" deletes the selected preset(s) from the list.
    - "Rename" changes the name of the preset (accelerator: click a
    selected item on the list.)
    - "Up" moves the selected preset one position up the list.
    - "Down" moves the selected preset one position down the list.

    Buttons "Save List", "Reload List", "New", "Import" are always
    enabled.
    Buttons "Apply", "Store", "Rename", "Up", Down" are enabled when
    only one item in the list is selected.
    Buttons "Export", "Delete" are enabled when one or more items in
    the list are selected.

Every plugin has two presets files (system and user) organized in a
tree following the DSSI recommendation.

Raptor writes NTriples, which is a subset of Turtle.

QLoud is a tool to measure loudspeaker frequency response. Find it here: 

     http://gaydenko.com/qloud/


Uwe has released Qwt v.5.0.0rc0. As a result, QLoud doesn't depend on any CVS tree now.
v.0.16 is out - INSTALL is changed to be in accordance with Qwt development. Also, min.
smoothing was reduced to 1/1024 :-)

If you already use the app, you can stay with v.0.15 (no bugs were found).
If you have rejected the app because of Qwt CVS-tree dependency - try it now :-)

Yes, it seems to be great! But the project would be xx times greater
if there were some screen shots plus a simple example host so that
it'll be easier for us to add FLAM into our own software.

(And in case those things already exist, make them easier to find on
the web-page)

---------------------------
-Updated Snd from 8.0/2.4.2006 to 8.4/13.9.2006. Many important fixes.
-Added --fast-math as default cflags option.
-Various fixes.

Message-ID: <200609191933.20259@goldspace.net>

Hi!

Please, recomend a sound card with the best SPDIF out. Must be supported:

- ALSA support,
- stereo playing back,
- up to 96KHz sample rate,
- up to 24 bit depth,
- coaxial SPDIF out (optical is optional),
- of course, without resampling,
- (most important) minimal jitter.

Assumed using is a stereo playing back with an external DAC.
Preferably, without an overloading (MIDI, multiple analog ins/outs and so on).
Moreover, ADC/DAC may be absent at all :-) USB (rather PCI) variants are
acceptable also.


Thanks in advance!

Rates are: 44100, 48000, 96000.

Lee, sorry, didn't understand 'function of the host OS and driver'
(probably, my English isn't perfect :-)). As I understand a problem,
for PCI case proper shielding, clean (on the card) power supply
subcircuits and good generator are useful. For USB case - all these
and syncing from *own* oscillator.

Of course, all these is costly, but without DAC/ADC, MIDI and such
it may be suitable.

Thanks for the advice, but I am still in the process of adding basic
functionality, as stated in my first post. There is a step-by-step
tutorial with screenshots in the TODO list before the time for a
official release comes.

As hosting is concerned, you just have to extend the DSSI GUI protocol
to LADSPA plugins. This works already in Rosegarden. There are some
hints at the README file on how to design and install a GUI.

Cheers,

Forget about USB, unless you're forced to e.g. on a laptop. 

For PCI cards, the M-Audio Delta cards are very good and not too
expensive. If you only need stereo, then the M-Audio Delta Audiophile
PCI is a very good and popular choice.

It is well supported and does exactly what you need.  You can find them

Be aware the Audiophile 192 is NOT supported.

2496, the AP192 is hardly supported at all due to lack of help from
M-Audio.

Talking of which: Today I found an advertisement in my (physical)
mailbox for a laptop in the sub 100 Euro range. I even managed to google
out the sound chipset which is a Realtek ALC260, aka:

0000:00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High
Definition Audio Controller

The bad news: It is supported by ALSA buut .... No sound :-D

The good news: Somebody[*] figured out that the (same) chip can be
configured in several  ways, and posted a patch for an HP dc7600:

Is this patch back in the trunk by now? Hi profiled projects like

QLoud is a tool to measure loudspeaker frequency response and (yes!) distortions.
Find it here: 

     http://gaydenko.com/qloud/

Changes:

- harmonics (distortions) plotting is added,
- as a result, noticeable part of common code was refactored/rewritten.

Direct screenshot link to harmonics plot:

If you have a sound card with good DAC and ADC, you can plot harmonic
distortions for another audio equipment, say, for your power amplifier -
cited screenshot has also harmonics plot for loopbacked sound card.

Hi,

this is a small announcement for a minor update for a minor piece of software, 
and at the same time a question :) So here it goes:

Kontroll is a small utility that generates midi cc messages from the mouse 
position. It is inspired by the MouseX and MouseY UGens in Supercollider. It 
simply creates an alsa sequencer port which you can then connect with your 
favourite patchbay. The mouse position is independent of window focus and is 
relative to the screen origin at the upper left.

- Another small update to kontroll. Now the controller and channel numbering 
range from 1-128 and 1-16 as commonly seen in other midi applications and 
hardware. previously it as 0-127 and 0-15 which was probably confusing to non 
computer people. 

- A minor update to this little program of mine called ?Kontroll?. On shutdown 
it saves the last used parameters to a file called ~/.kontroll and on startup 
reads it again. This saves setting it up all over again on each start of the 
program. You can also save special setups via the ?File? menu. 

Grab it here:

http://tapas.affenbande.org/?page_id=42

Or directly:

http://affenbande.org/~tapas/kontroll.tgz

And here's the question: A user suggested (and i'd like this idea very much) 
that kontroll be able to make use of other input devices attached to the 
computer (additional mice, joysticks, etc). Now i would like to avoid playing 
with /dev/input directly, cause i imagine it to be a drag. So does anyone of 
you guys know a small and easy to use input-library that makes accessing 
these devices a breeze? If so, please let me know.

Regards,
Flo

P.S.: Ah, LASH support is still missing. Will add it right away (or at least 
try) ;)

I wasn't aware that there is an Audiophile 192 as well. I was talking

Message-ID: <4517BCF6.8010007@woh.rr.com>

Greetings:

Recently I tested Robert Reif's ASIO driver for WINE. It works okay for 
some small test apps (asiosiggen and asiodump). I also tested it with 
NI's FM7, the app opens fine but I got no sound from it. I even loaded 
and played a MIDI file as a demo but still got no joy from the audio.

I'm curious to try other ASIO-driven apps but I need some 
recommendations for light-to-middle weight programs for testing. 
Free/shareware is best, but feel free to suggest commercial apps too. I 
don't use Win/Mac music apps and I have no idea where to start.

Best,

You could look at how it is done in SuperCollider, it is not so complicated.

Or look up specifications of the "event" interface, there are clear examples 
of how to open a device and see what it does.

While SDL is fine for joysticks it doesn't seem to provide access to 
additional mouses / tablets, etc.. I'll add preliminary joystick support 
using SDL though as a first step.

while using the input layer is not very complicated (see
SC_LID.cpp in supercollider for some examples), it's of
course limited to linux. i've had a glance at libggi/libgii
as a cross-platform alternative, but haven't used it yet ...

Some things relate to the tcl-language not much clear :)

This is a code that would work as you want:

#start example
package require snack

snack::sound s

proc Record {} {
s record
after 5000 sstop
}
proc sstop {} {
     s stop
     set filename "tmpwave.wav"
     s write $filename
     s destroy
puts "this goes well"
exit
}
Record
#end example

hope help

Thanks for the hints. Will take a look at libgii and the SC stuff. I also took 
a look at the evdev documentation in the kernel tree, but it left quite a few

Have you try snd-ls? it is an snd version that is easier to use.

Dominique,

Yes, I have. The thing is I don't know how to force snd(-ls) to open 32float PCM
(wav) files.

Have you try snd-ls? it is an snd version that is easier to use.

Hi!

Can anybody point me to theoretical and algorithmic fundamentals
of real-time (JACK-oriented) (pseudo)pink noise generation at
given frequency range?

Message-ID: <451AF83B.3010009@superbug.co.uk>

Hi,

I was wondering if there are any tools out there to test audio
resampling quality. I am particularly interested in 44.1kHz to 48kHz
resampling due to the fact that most sound cards prefer 48kHz.

At least with up sampling (low rate to higher rate) one does not get
aliasing.

I really just want to find some algorithm that I can use to compare
44.1kHz audio signal with an 48kHz audio signal, and to see if there has
been any lose of quality during the up sample.

I'm not sure if it's a good technique, but to test my dithering algorithms
I took high precision FFTs of the input (sine wave IIRC) and output
signals and looked for extranous peaks. You can see the test code in the
tarball: http://plugin.org.uk/libgdither/libgdither-0.6.tar.gz

It is not quite that easy. The buckets for FFTs at 44.1kHz rate might be
different from the buckets at 48kHz rate. Some of the buckets are the
same, but not all. I.e. the 1 Hz and the 2 Hz buckets are the same, but
the buckets above 44.1kHz might be different as the 44.1kHz rate FFT
will not have baskets above 44.1kHz.

Err, sorry, aliasing can also be produced during up sampling; in
particular, aliasing can be created in the fs/2 to fd/2 band where
fs is the source sample rate and fd is the desitination sample rate.

The Secret Rabbit Code test suite has some pretty extensive SRC
test code. YOu can get the Rabbit here:

    http://www.mega-nerd.com/SRC/

and I gave a bit of a talk about this stuff at an LCA minconf in
2005. The slides are here:

I am using the following for testing my resampler code:
 - generate sine signal
 - upsample it
 - generate expected sine signal
 - subtract those two

It only works if you precisely know how much delay the upsampling
introduces, but if you know this, then you can compute the exact maximum
error between these two signals and get a dB error value. If you repeat
the test for many different frequencies, you can plot how your resampler
performs at different frequencies.
