We released a new version of our A-SID plugin that fixes a couple of
bugs, making it finally work with Reaper and Bitwig Studio on Linux.
A-SID implements a wah effect as a C64 program and a VST3 plugin. More

We just ported our A-SID VST3 plugin to Linux.
A-SID is our personal and romantic way to celebrate the 40th anniversary
of the debut in 1982 of the most successful computer ever, the C64.
It implements a wah effect as a C64 program and a VST3 plugin.
The C64 program uses the SID chip in the original machine. No hardware
modification is required, but you need to build yourself one or two
adapter cables and copy the program to a cassette.
The VST3 version emulates the original analog filter (the MOS 8580
version) and replicates the C64 program.
Both versions are GPLv3 licensed.

Creating this software has been a fascinating journey that absorbed an
immense quantity of energy and time, as we documented on our blog:
https://www.orastron.com/blog/asid-trip-part-1. We would really
appreciate if you could spread the word about A-SID and Orastron with
friends and on social media, forums, etc. Bluntly put, we'd love to make
innovative premium consumer products, but we first need an audience for
that to be economically viable.

XUiDesigner v0.7 released
A easy to use tool to generator/design X11 based LV2 plugins.
Beside that XUiDesigner allow to generate and install GUI's for existing
LV2 plugins, it support as well to generate LV2 plugins from scratch.
Special support is implemented for FAUST dsp files, which allow you to
generate a LV2 plugin with X11 based UI by just drag'n'drop a FAUST dsp
file into the XUiDesigner interface. This works now as well for MIDI
capable faust modules.
In any way, you don't need to interference with any of the annoying LV2
implementations. XUiDesigner handle that all for you.
The very same is true when you like to implement your own dsp (C or C++)
into a LV2 plugin. You could create the GUI interface, save the plugin
bundle, and implement the needed calls to init, activate and run your dsp.
This release comes with a couple of Bug-fixes and aims to be nearly stable.
Here is a introduction Wiki
<https://github.com/brummer10/XUiDesigner/wiki/XUiDesigner> entry to
show the first steps.
New in this release:
implement interim save format (json)
(Allow to load and rework the generated UI in XUiDesigner at any time)
DrumGizmo 0.9.20 Released!
DrumGizmo is an open source, multichannel, multilayered, cross-platform
drum plugin and stand-alone application. It enables you to compose drums
in midi and mix them with a multichannel approach. It is comparable to
that of mixing a real drumkit that has been recorded with a multimic setup.
This release was originally intended as a bugfix release, but quite a
few features also managed to find their way in.
Noteworthy bugs that has been fixed:
* Software regression error in cymbal choke code has been fixed. So
now choking of cymbals using both directed chokes and after-touch midi
events work again as expected.
* A compilation error due to an update in LV2 API (we used an
obsolete LV2 type) has been fixed, so now compilation should work for
* Code can now properly be compiled with NSL support disabled at
* Compilation with the modern gcc-11 compiler has been fixed.
As usual read the detailed description of all the new shiny features,
see the detailed changelog: .
And now, without further ado, go grab 0.9.20!!! 
Linux-audio-announce mailing list
audiowmark-0.6.1 is now available at https://uplex.de/audiowmark
Overview of Changes in audiowmark-0.6.1:
* improve speed detection/correction
- performance optimizations to make --detect-speed faster
- improve accuracy of speed detection
- make it work properly with short payload
- add second, slower / more accurate algorithm (--detect-speed-patient)
* fix segfaults during hls-prepare (#11)
* read all input if a process provides audio on stdin to avoid SIGPIPE (#19)
* improve infrastructure for testing audiowmark
- run some scripts for 'make check' to ensure everything works correctly
- add CI which builds/tests audiowmark automatically using github actions
- support various sanitizer builds / STL C++ debug builds
- fix some issues triggered by sanitizers
* add --strict option: provide strict and more permissive mode
- "input frames != output frames" is only an error if --strict is used
- enforce payload size if --strict is used
* improve command line parsing error messages
* documentation updates
* minor fixes
audiowmark is an open source solution (GPL3 or later) for watermarking
audio files. It has many features, it is robust, fast, secure and of
course we believe that the watermark is not audible for most users.
The project page provides the documentation and source code as well as
some audio demos, so you can check whether you hear a difference between
original and watermarked files.

This project is a Linux MIDI Synth library based on the Sonivox EAS
Synthesizer published by Google on the Android Open Source Project. It is a
real time MIDI wave table GM synthesizer and SMF player without needing
external soundfonts, using embedded samples instead. It consumes very
little resources, so it may be indicated in Linux projects for small
The library uses ALSA Sequencer MIDI input and PulseAudio output. Complete
compile-time dependencies are:
* Qt5 / Qt6
* Drumstick 2, for ALSA MIDI input.
* PulseAudio, for audio output.
The project contains:
* cmdlnsynth: Command line sample program using the synthesizer library
* guisynth: GUI sample program using the synthesizer library
* libsvoxeas: The Linux synthesizer shared library, using ALSA Sequencer
* sonivox: The AOSP source files as a git submodule, or an external shared
library dependency: https://github.com/pedrolcl/sonivox
* Some general fixes
- fixed guisynth underlinking.
- fixed program icon in KDE+Wayland.
* Fixed tickets: #3 and #4
- allow to build with Qt6 without mixing Qt5 libs.
- errors initializing ALSA, Pulse and Sonivox emit qFatal.
* Fixed ticket #2
- icon.png file was installed in the wrong place.
- added the original SVG icon, and two other icon sizes.
* Linked to the shared sonivox library instead of the static one
