aloop is a audio file looper for Linux using PortAudio as backend (jack,
pulse, alsa), libsndfile to load sound files and zita-resampler to
resample the files when needed. For varispeed, fine tuning and pitch
shifting it use librubberband. The GUI is created with libxputty.
This release add support for varispeed, fine tuning and pitch shifting,
contributed by @rubberplayer <https://github.com/rubberplayer>
<https://github.com/brummer10/aloop/blob/main/alooper.png?raw=true>
aloop comes with the following features:
* support all file formats supported by libsndfile.
* resample files on load to match session Sample Rate
* file loading by drag n' drop
* included file browser
* open file directly in a desktop file browser
* open file on command-line
* create, sort, save and load playlists
* select to loop over a single file or over the play list
* move play-head to mouse position in wave view
* set loop points for start/end loop
* save loop points in play list
* save selected loop as wav file
* play backwards
* volume control
* endless looping
* break playback (keyboard support space bar)
* reset play-head to start position (keyboard support courser left)
* varispeed
* fine tuning
* pitch shifting
To build from source please use aloop-v0.4.tar.xz as only this contain
the needed submodules to build aloop successful.
Dependencies
* libsndfile1-dev
* portaudio19-dev

This is the first release of NeuralRack.
NeuralRack is a Neural Model loader (based on Ratatouille), it allow to
load two model files and run them serial.
The input/output could be controlled separate for each model.
It supports *.nam files <https://tonehunt.org/models?tags%5B0%5D=nam>
with the Neural Amp Modeler
<https://github.com/sdatkinson/NeuralAmpModelerCore> engine, or *.json
or .aidax files <https://tonehunt.org/models?tags%5B0%5D=aida-x> with
the RTNeural <https://github.com/jatinchowdhury18/RTNeural> engine.
For tone sharping a 6 band EQ could be enabled.
NeuralRack provide a mono input and a stereo output.
Additional it allow to load up a separate Impulse Response file for each
output channel (stereo).
Neuralrack provide a buffered Mode which introduce a one frame latency
when enabled.
It moves the complete processing into a background thread. That could
reduce the CPU load when needed.
The resulting latency will be reported to the host so that it could be
compensated.
NeuralRack could be build as LV2 plug or/and as stand alone application.
Stand alone it could be used with JackAudioConnection Kit or with Alsa
(pipewire).

Release Page with pre-build binaries is here:
https://github.com/brummer10/NeuralRack/releases/tag/v0.1.1
Ratatouille is a Neural Model loader and mixer for Linux/Windows.

This release Fix a issue with the lv2 plugin from last 0.9.8 release
which leads to a crash on several hosts.
It also introduce a stand-alone version for Linux and windows.
Stand-alone app will auto save and reload the last used settings.
A prebuild binary of the app is provided here in
Ratatouille.lv2-app-v0.9.9-linux-x86_64.tar.xz/
Ratatouille.lv2-app-v0.9.9-win64.zip
Note that the binary is fully optimized, so when your CPU didn't support
x86-64-v3 the only way to get it is to compile it yourself.
Ratatouille allow to load up to two neural model files and mix there
output. Those models could be [*.nam files](https://tonehunt.org/all) or
[*.json or .aidax files](https://cloud.aida-x.cc/all). So you could
blend from clean to crunch for example, or, go wild and mix different
amp models, or mix a amp with a pedal simulation.
Ratatouille using parallel processing to process the second neural model
and the second IR-File to reduce the dsp load.
Ratatouille allow to compensate phasing issues between the loaded Models.
The "Delay" control could add a small delay to add some color/reverb to
the sound.
To round up the sound it allow to load up to two Impulse Response files
and mix there output as well. You could try the wildest combinations,
or, be conservative and load just your single preferred IR-File.
Each neural model may have a different expected Sample Rate, Ratatouille
will resample the buffer to match that.
Impulse Response Files will be resampled on the fly to match the session
Sample Rate.

have fun
In case you have missed both the original deadline and our announcement
for extending it:
IEM (iem.at) and the SMC network (smcnetwork.org) extends its call for
paper contributions to SMC, which will be held in Graz, consisting of a
summer school between July 7th and 9th, and the conference/concerts as
main event between July 10th and 12th at MUMUTH/Kunstuni Graz, 2025.
The new submission deadline for papers is **March 12th 2025**.
See <https://smc25.iem.at> for details; we chose "Auditory Landscapes"
as a theme.

Hello all,
Anyone familiar with Scala files ?
After reading <https://www.huygens-fokker.org/scala/scl_format.html>
one questions remains.
For scales with 12 notes in an octave, to which note does the
first (implicit ratio 1.0) pitch refer ?
I assume this is C, not A.
That would mean that a software instrument having a control
to set the absolute 'A' pitch should shift the entire scale
so that the 'A' pitch is the one set by that control.
Is this the correct interpretation ?
Ciao,
