Hello all,
The first release of pyjacktools is now available at
<http://kokkinizita.linuxaudio.org/linuxaudio/downloads>
Python C++ extensions and classes for audio. I wanted to demo
these during the Audio Measurements workshop at LAC 2014, but
we ran out of time...
AudioFile
Read/write audio files to/from numpy arrays. Reads anything
libsndfile can read, and writes wav, wavex, amb, aiff, caf
and flac, any number of channels.
JackControl
Simple Jack client allowing to connect arbitrary ports and
control Jack transport.
JackPlayer
Multichannel (up to 64) audio file player. The interface is
deliberately kept low level, but it's easy to create derived
classes providing a higher level interface. This is the player
used in the automated systems at La Casa del Suono in Parma.
JackSignals
Generate and capture arbitrary test signals from/to numpy
arrays. Combined with numpy, matplotlib, pyqt, etc. this
can be used to create anything from a simple measurement
to sophisticated automated test systems.
All four classes are documented using Python docstrings (use
Python's help function to read these). Some simple examples
are provided as well.
The C++ extenstions should work with either Python 3.x or
2.7. The Python code is tested using Python 3.4, but will
probably work even with 2.7. If not the required changes
should be minimal.
To install you need the Python setuptools, then just make
and sudo make install. The examples require numpy and for
some also matplotlib.
Enjoy !

Hi,
I recently moved with my Band (www.jimson-drift.de) into a new
rehearsalroom. I'm thinking of building a drum booth especially for
recording. Can someone point me to the right literature? I'm interested the
Physics of room acoustics and would like to first understand the problem
theoretically (that means the math). I want to understand the
distribution of the acoustic modes of a given room in order to
optimize/minimize their amplitude, as well as the
reverberation/reflection aspects of different materials. Just want
deeper insights to plan the booth.
Thanks,
Gerald

I don't know if anyone here has heard about this. I discovered the link quite by
accident.

If you're using 3.17 it might be an idea to step back to 3.16, which so far
seems to be OK. I've been using 3.16 for several months now and not had any
problems.

Say you have a poem and I have a tune.
Exchange them and we can both have a poem, a tune, and a song.
Aw, snap!
Wait, there's no big deal (nor chromium's) cosmic (mis)alignment
being announced here now. Rest calm. Sorry to delude some of you :)
But, there's one (notable) leap on this tiny side and part of the
universe... (or is it a multiverse? move along...) What I really want to
tell is all about this happening and none else's freaking business:
Qtractor 0.6.4 (baryon throne beta) is released!
Release highlights:
* Punch-in/out over loop-recording/take modes (NEW)
* Latch/momentary MIDI Controllers toggle mode (NEW)
* JACK client/port pretty-name (metadata) support (NEW)
* Custom style and color themes (NEW)
* Mixer strip multi-row layout (NEW)
* Muted audio tracks monitoring on playback (FIX)
* Clip fade-in/out resize on time-stretch (FIX)
As for the clueless (as if there's any):
Qtractor is an audio/MIDI multi-track sequencer application written
in C++ with the Qt4 framework. Target platform is Linux, where the Jack
Audio Connection Kit (JACK) for audio and the Advanced Linux Sound
Architecture (ALSA) for MIDI are the main infrastructures to evolve as a
fairly-featured Linux desktop audio workstation GUI, specially dedicated
to the personal home-studio.
Well, although this being yet another milestone--if one may call it
that way--it also makes it official (yes, deeply engraved in stone) and
definitive as a migration to Git can be, as for source-code control and
management (it's a dirty job I know, but someone has to do it, right?).
Nevermind. It's done.
Meanwhile, please, don't ever hesitate to ask whether any of the
above does affect you some way or another. Or maybe anything else, yay?
Indeed, the puzzled you feel, the better :)

Change-log:
- Fixed some old loop-recording clip drawing glitches.
- Current assigned track/channel instrument definition names for MIDI
controllers, note keys, RPN and NRPN, are now in effect on the MIDI clip
editor drop-down lists, whether available.
- Clip/Take/Range... input dialog values are now properly sanitized as
long to prevent invalid take/folding ranges.
- Audio capture/export file type default now set to "wav".
- Extending punch-in/out over loop-recording/takes modes.
- Make audio tracks monitoring always flow while playback is rolling,
independently of their mute/solo state.
- Fixed undo/redo conversion of audio clip offsets under (automatic)
time-stretching eg. due on tempo changes. (ticket by Holger Marzen, thanks).
- Latch/momentary MIDI Controllers toggle mode introduced (a request by
AutoStatic aka. Jeremy Jongepier, thanks).
- JACK client/port pretty-name (metadata) support is being seamlessly
introduced. (EXPERIMENTAL)
- Audio frame/MIDI time drift correction is now an option on
View/Options.../MIDI/Playback/Enable MIDI queue time drift correction.
- Transport auto-backward feature now honoring last position playback
was started.
- Introducing brand new application user preferences on
View/Options.../Display/Options/Custom style and color themes (eg.
"KXStudio", by Filipe Coelho aka. falkTX).
- Mixer widget gets automatic multi-row strip layout.
- Clip fade-in/out now follows time-stretch resizing, via
shift/ctrl+click and drag one of its edges.
- Fixed a typo causing FTBFS when VST plug-in support is explicitly
disabled (./configure --disable-vst).

The Guitarix developers proudly present
Guitarix release 0.32.0
For the uninitiated, Guitarix is a tube amplifier simulation for
jack (Linux), with an additional mono and a stereo effect rack.
Guitarix includes a large list of plugins[*] and support LADSPA / LV2
plugs as well.
The guitarix engine is designed for LIVE usage, and feature ultra fast,
glitch and click free, preset switching, full Midi and/or remote
controllable (Web UI not included in the distributed tar ball).
Here is the " Ultimate Guide to Getting Started With Guitarix
<http://libremusicproduction.com/articles/ultimate-guide-getting-started-gui…>"
This release fix the bug #16 "empty effect menu with clear-skin option",
add new tuning scales (19- and 31-TET) to guitarix and Gxtuner.lv2,
add Midi Clock and Jack Transport support to guitarix and move a couple
of controllers from
unit:ms|hz to unit:bpm, so that they could easy synced with the Midi
Beat Clock.
and introduce a new LV2 plug:
* GxMultiBandReverb

Is there a way to retrieve this info (and others, ideally) from the
host, thus removing the need for a "midi channel" control port?
Also, is there a way to tie the "volume" controller of the host (in
Qtractor's case, the volume fader of the mixer strip) to one "volume"
control port of the plugin, thus removing the need for the "control
mode" control port ?
Yes because you see, here in my Qtractor (latest SVN - but it has always
been that way) I can either edit the plugin (about 50% of my plugins
behave that way) controls but then the mixer's volume is inoperant, or
control the volume w/ said mixer but NOT the plugins controls. How can I
have my cake and eat it?

Hey list,
I'd like to be able to stream DTS-HD Master Audio bits out the HDMI port
in their compressed form - not decompressed to LPCM. I'll let the
receiver handle the decoding.
From what I can gather, this may be possible with the ALSA API,
provided the HDMI port is >= 1.3 and the audio card supports high
bit-rate (HBR).
Is my thinking way off? Is there a more suitable API or approach for
this? If it requires specific hardware, I am less concerned about that
as I am the feasibility of the end goal.
Regards,
