[LAD] Updates of zita-audiotools and zita-jacktools

[Fons Adriaensen]

Hello all,

zita-audiotools-1.3.0 and zita-jacktools-1.6.0 are now available at
.

If you have previous versions, installing these updates will require
some extra work. This is for two reasons:

* The python package names have changed:
audiotools -> zita_audiotools
jacktools  -> zita_jacktools

* The setup.py files now use setuptools instead of the deprecated
  distutils, and will install a python 'egg' directory.

This requires the following actions:

* Before installation, remove all traces of any previous versions
  from your python site-packages directory. Then just make; sudo
  make install; sudo make clean.

* In existing applications, the import statements must be modified
  to refer to the new package names.


Thanks to Marc Lavallée for both suggesting the name change and
testing the new releases.

Nothing has changed in the Aeolus code, and I haven't seen this 
on any on the 20 or so systems it was tested on. Probably some
problem with your desktop / window manager / X11 system.

That is what pkgconf --cflags freetype2 is supposed to do. 
Could you be using an older version of freetype ? It used to have its
own config command which was removed and replaced by using pkgconf 
in recent releases. This was one of the reasons to review all of
the Makefiles.

jack_connect called with a NULL port name

jmeters' input port shows up with jack_lsp as "jmeters:in-1" though.

[LAD] Updates

[Fons Adriaensen]

Updates available now at 
http://kokkinizita.linuxaudio.org/linuxaudio/downloads

zita-alsa-pcmi-0.2.0

* Now includes some dirty hacks (implemented via the debug
  options parameter so they don't clutter the API) to support
  the -L option of

zita-ajbridge-0.2.2

* Fixed the bug that made it fail with Jack period sizes 
  = 1024 (filter coefficients going out of range).

* Added some hacks, activiated by the -L option, to make
  it work with ALSA's loop devices.


The latter requires some clarification.

The two apps provided by zita-ajbridge were never intented to be
used with the ALSA loop devices. They were developed to provide
additional and full quality capture or playback channels to Jack,
using a real soundcard. 

Yet most people trying the first release used them with the
loop devices, to provide a Jack interface to some misbehaving
apps such as flash player or skype. Using the loop device is
required since those apps refuse to work with ALSA's Jack
plugin. It's a dirty hack using an unwanted resampling step,
but it seems there is no working alternative.

The ALSA loop devices presents themselves as hw: devices, but
they don't behave like a real one:

* Timing of period wakeups is quantised to a much too high
  value, and produces lots of jitter, worse than even the
  most crappy USB interface. It also makes using the device
  with small period sizes impossible, as wakeups occur when
  it's almost too late. The next cycle will xrun in that case.

* The loop devices have 32 channels. They allow to be opened
  with a different channel count at both ends, but then make
  a mess of it. For example mplayer's two channels will be
  spread out over the available 32, making it run at 16 times
  normal speed. 


To run zita-a2j or zita-j2a with the ALSA loop device:

* Use the -L option. This forces two things: the sample format
  will be 16-bit, and the device is opened in 2-channel mode.
  This makes it usable to apps at the other end which can't deal
  with floats or more than 2 channels.
  Note that just using -c 2 (which is also the default) still
  opens the ALSA device with all its channels, as must be done
  on a real hw: device, so that won't work.

* Use at least -p 256 -n 3, or -p 512 or higher (on the ALSA
  device - Jack's parameters don't matter).

[LAD] Updates beta testers wanted

[Fons Adriaensen]

Hello all.

Some updates available on
http://kokkinizita.linuxaudio.org/linuxaudio/downloads


Zita-resampler is a C++ library for sample rate conversion of
audio signals. Full documentation is available in HTML format,
see the 'docs' directory.

Release 1.1.0  (26/01/2012)
---

* VResampler class added - provides arbitrary and variable
  resampling ratio, see docs.

* This release is NOT binary compatible with previous ones
  (0.x.x) and requires recompilation of applications using it.

* This release is API compatible with the previous one. But if
  you are using the now deprecated filtlen() function please
  replace this by inpsize() which provides the same information. 

* The inpdist() function has been added, see docs.

* The ratio_a() and ratio_b() calls have been removed, if this
  is a problem (I'd be surprised) they can be added again.

* The include files are now in $PREFIX/include/zita-resampler/.
  Please DO remove any old ones manually after installing this
  version. Compiling using the old includes and linking with
  the new library will create havoc.

* #defines and static functions are added for compile time and
  run time version checking, see resampler-table.h. 


Zita-alsa-pcmi is the successor of clalsadrv. It provides easy access
to ALSA PCM devices, taking care of the many functions required to
open, initialise and use a hw: device in mmap mode, and providing
floating point audio data. 

Release 0.1.1  (26/01/2012)
---

* This release is almost API compatible with clalsadrv-2.x.x.
  The only changes your source code will need are:

  - Change the include file.
  - Change the type of any objects defined by the library.
  - Replace calls to stat() by state(). 
  - If you want error reporting on stderr, add an optional
parameter to the constructor. See include file for details.

* Added support for big-endian PCM formats.

* Added support for reading and writing interleaved user buffers.

* Error messages on stderr can be selectively enabled. If an app
  is compiled without them, they can be re-enabled at runtime by
  defining the environment variable ZITA_ALSA_PCMI_DEBUG, so they
  are now by default off. See source code for details.

* Two simple demo programs are provided, one of them is the ALSA
  version of jack_delay. Complete documentation will follow later.


The clalsadrv lib will remain available for some time, but any
new releases of JAAA and JAPA will switch to the new one. Patches
for AMS are being prepared.


Both libraries have been updated mainly to provide the necessary
functionality for two new apps: zita-a2j and zita-j2a. These allow
to add ALSA hw: devices as a Jack client, same as the alsa-in and
alsa-out clients that come with Jack. To see why I wanted something
to replace those, have a look at
http://kokkinizita.linuxaudio.org/linuxaudio/resample.html

Both apps still need some cosmetics but they are in a working state.
I'd want some more testing before they are released. If interested
drop me a line off-list.

[LAD] Updates from kokkinizita

[fons]

Hello all,

Some updates are available on 
http://www.kokkinizita.net/linuxaudio/downloads

1. libclalsadrv-2.0.0

This the the Alsa interface library used by Aeolus, Jaaa,
Japa and AMS. 

The new release allows to specify separate Alsa device 
names for playback, capture and control, i.e. it allows
the use of 'split' devices that may result from e.g.
combining several soundcards into one device.
The old API is still available but will be removed in
future releases.
Note that 2.0.0 is *not* binary compatible with the
previous release (hence the major version increment),
and may require a recompile of the apps using it.

There are two example programs in the 'apps' directory.
* alsa-loopback: just copies stereo input to output.
* alsa-latency: latency measurement, same algorithm
  as used in jack_delay.

2. jaaa-0.6.0 and japa-0.6.0

* General cleanup, now compile without warnings using
  gcc-4.4.3.
* When using Jack, a new option (-s) allows to specify
  the Jack server to use.
* Require libclalsadrv-2.0.0.
* When using Alsa, two new options (-P, -C, used instead
  of -d) allow to specify a split Alsa device. 
* Added $(DESTDIR) to the Makefiles.

3. Aeolus-0.8.4

* Same changes as for Jaaa and Japa (except for -C, -P).
* Five new temperaments added, provided by Hanno
  Hoffstadt and Adam Sampson.


Note to AMS users: if you have a binary install of AMS
make sure not to remove the current libclalsadrv. If you
have a source install, update libclalsadrv and recompile
AMS.

Hello all,

Some updates on http://www.kokkinizita.net/linuxaudio/downloads:

jmeters-0.2.0   

   - VU-meter scale replaced by a new one which does
 not have the -20dB threshold. Now it will also
 move for low-level sounds, and fall back much
 more naturally.

   - PPM now has the same size as VU. Old one still
 available as ppm2.

   - Added options to set jack client name and update
 rate.

   - Bugfix for Makefile, PNGs now get installed in
 $(PREFIX)/share instead of /usr/share.


aeolus-0.8.1
 
- Aeolus-0.8.0 added Midi over Jack support but was
  announced on the Aeolus list only IIRC. With 0.8.1
  it's official.

- Major cleanup and bugfixes. 

- Replaces 0.6.6. as the supported release.  

ambdec-0.2.0
 
- Bugfixes, new collection of config files.

MCP-plugins-0.4.0

- Major cleanup (after 5 years or so). 
- Added triple chorus. Same as chorus2 but has three
  outputs. Pan L,C,R for a nice stereo effect.

clthreads-2.4.0

- Cleanup.

clxclient-3.6.1

- Cleanup.
- Probably fixes a bug that occurs only when running

Many thanks to all who contributed by providing feedback,
bug reports and patches.

The two libs and ambdec now also have an OSX Makefile and
the necessary #ifdefs to make them compile. This is very
experimental. I will provide *no* support for this except
to OSX developers who can provide the required technical
feedback.

[LAD] Updates and new stuff

[Fons Adriaensen]

Hello all,


Some updates and new things on my webpages.


First official release of jconv.

  Jconv is a command line jack client performing FFT-based
  convolution using a mix of up to five partition sizes,
  small ones at the start of the IR, and building up to
  the optimum size further on. It allows zero-delay 
  convolution with moderate CPU load. Jconv uses the
  multi-threaded convolution engine developed for use
  in Aella, a convolution engine optimised for reverb
  processing that is nearing completion.

  Main features of jconv:

  - Any convolution matrix up 64 by 64, as long as your
CPU(s) can take it.
  - Allows to trade off processing delay to CPU load, and
remains efficient even when configured for zero delay.
  - Reads the same config files as Jace which it will 
eventually replace.

  The beta version released two months ago to some
  volunteers contained a bug discovered and patched
  by Martin Rumori. It did not affect configurations
  using independent 1-to-1 convolutions, only matrix
  operations.


Update of Ambdec

  Some small changes and bugfixes. The configuration
  format now also permits the use of mixed-order de-
  coders (2nd order horizontal, 1st order vertical). 
  Manual updated.


TetraProc / TetraCal.

  Both are ready and have been used for real Ambisonic
  recordings, but release of TetraCal awaits a required
  update of Aliki, and completion of the manual that
  describes the calibration procedure.

  If you want to use Core Sound's TetraMic with 
  TetraProc this is possible today. I signed an NDA
  with Core Sound giving me access to the impulse
  response measurements performed by Core Sound on
  each mic. Given the serial number, I can process
  these using TetraCal and provide a matching config
  file for TetraProc.
 
  You can see some examples of this on the updated
  screenshots page for TetraProc.

Ken's blog http://www.restivo.org/blog/archives/80, mentions the
Lucia IR used in jace's demo configuration. I'll have to temper
Ken's excitement a bit: it is not Santa Lucia Basilica in Siracusa,
but the one in Bologna, now the university's aula magna. See here:

Still a nice place to shake the plaster off the walls :-)
