[ANN] Qtractor 1.5.8 - A Late Summer'25 Release

by Rui Nuno Capela

Hi all, Qtractor 1.5.8 (late-summer'25) is released! Change-log: - When selecting an Aux-Send pseudo-plugin, also highlight the respective target output bus mixer strip. - Mitigate and compensate for padding and start-delay/latency to (lib)RubberBand time-stretching and pitch-shifting processing. - Avoid warning when auto-saving an extracted archive/zip session. - Fixed all empty/void audio clips created when aborting an armed recording session; revisited. - Added new Track/Height/Minimize menu item. - Fixed initial Aux-Send audio bus I/O matrix functionality; also when input channel count is greater than output count. - Fixed WSOLA time-stretching crashing on greater-than-2-channels/stereo audio clips. - Fix misaligned LV2 Atoms. Description: Qtractor [1] is an audio/MIDI multi-track sequencer application written in C++ with the Qt framework [2]. Target platform is Linux, where the Jack Audio Connection Kit (JACK [3]) for audio and the Advanced Linux Sound Architecture (ALSA [4]) for MIDI are the main infrastructures to evolve as a fairly-featured Linux desktop audio workstation GUI, specially dedicated to the personal home-studio.

Building Bristol?

by Lorenzo Sutton

Hi LAU/LAD, Anyone had luck compiling Bristol [1] recently? Both the AUR pacakge (seems sami-unmaintained) [2] and trying to compile from source fail with a bunch of errors. Besides an issue with the inclusion of alsa/iatomic.h which can probably just be removed, there seem to be a bunch of warnings (?) I do see that the latest release is 2013 so it's unsurprising that it won't compile on a more 'recent' system (I'm using Manjaro). So I'm wondering if the software is abandoned? Which is a pity because while I mostly use Yoshimi these days for 'synth needs' Bristol could definitely make some cool sounds with its emulated synths.

jack_is_realtime(client) issues

by Hermann Meyer

Hi I running into issues with the jack_is_realtime(client) currently. The issue is, when the user didn't have permission to run real-time tasks, jackd starts with no real-time permission but jack_is_realtime(client) reports true as soon the -R is in the jackd commandline. The same is true for jack_client_real_time_priority(client). This call reports the real-time priority given in the command line, but not the one in use. So, when jackd starts without real-time priority, but -R is given on the command-line, it reports the priority from jackdrc while it runs at SCHED_OTHER without any priority. Now, when I want to start my own threads I cant relay on the values reported by jackd, which render the functions useless. I need to run my own tests in order to check if real-time priority could be set by the user or not. regards hermann

Faust and runtime constant parameters

by Jeanette C.

Hey hey, I'm looking for a quicktip or the right section of the manual. I'm looking at Faust, specifically the oberheim.dsp example. This filter has a frequency given as a normalised frequency in the range of 0 to 1. As far as I have been able to work out: this means that the real frequency is multiplied by ma.SR ot ma.SR / 2. As a parameter range for a plugin or something this is not very useful. So, how can I create a parameter that is rescaled using ma.SR or any of such constants, that cannot be known at compile time? Best wishes and thanks, Jeanette -- * Website: http://juliencoder.de - for summer is a state of sound * Youtube: https://www.youtube.com/channel/UCMS4rfGrTwz8W7jhC1Jnv7g * Audiobombs: https://www.audiobombs.com/users/jeanette_c * GitHub: https://github.com/jeanette-c I'm reaching out to you To find that you're not there <3 (Britney Spears)

NeuralRack v0.2.0 released

by Hermann Meyer

NeuralRack is a Neural Model and Impulse Response File loader for Linux/Windows available as Stand alone application, and in the Clap, LV2 and vst2 plugin format. It supports [*.nam files](https://www.tone3000.com/search?tags=103) and, or [*.json or .aidax files](https://www.tone3000.com/search?tags=23562) by using the [NeuralAudio](https://github.com/mikeoliphant/NeuralAudio) engine. For Impulse Response File Convolution it use [FFTConvolver](https://github.com/HiFi-LoFi/FFTConvolver) Resampling is done by [Libzita-resampler](https://kokkinizita.linuxaudio.org/linuxaudio/zita-resam… New in this release: - implement Mix mode for IR convolver. - implement support for ASIO control panel (Windows) ![NeuralRack](https://github.com/brummer10/NeuralRack/raw/main/NeuralRack.png?raw=true) Neuralrack allow to load up to two model files and run them serial. The input/output could be controlled separate for each model. For tone sharping a 6 band EQ could be enabled. 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 could move one Neural Model, or the complete processing into a background thread. That will reduce the CPU load when needed. The resulting latency will be reported to the host so that it could be compensated.

[ANN] Dynamic Range Destroyer LV2 plugin (DRD.lv2)

by David Flater

Dynamic Range Destroyer (DRD.lv2 or simply DRD) is an audio compressor plugin that aims to remove changes in volume from an audio stream. This effect is also called auto volume levelling, volume normalization, or "stable volume." It supports mono, stereo, 6-channel, and 8-channel streams, and it preserves the balance among channels. https://github.com/DaveFlater/DRD

[ANN] Qtractor 1.5.7 - A Summer'25 Release

by Rui Nuno Capela

Hi all, Qtractor 1.5.7 (summer'25) is out! Change-log: - Give some slack time to stabilize, when updating or changing audio bus channel counts, mitigating the probability to fault when unregistering old and registering new PipeWire/JACK ports in immediate succession. - Transport/Loop Set behavior slightly changed, now toggling the loop range if the edit-head/tail match current loop-start/end. - Introducing Aux-Send audio bus I/O matrix functionality. - Corrected greater-than-2-channel audio clip waveform drawing, while on certain zoom levels, an old bug lurking there since dawn, quite an example to the evil of too-early optimization ;) - Draw all audio clip peaks+rms waveforms slightly compressed, so that low-level signals have improved visibility. - Warn when saving any type of session into an extracted archive directory. Description: Qtractor [1] is an audio/MIDI multi-track sequencer application written in C++ with the Qt framework [2]. Target platform is Linux, where the Jack Audio Connection Kit (JACK [3]) for audio and the Advanced Linux Sound Architecture (ALSA [4]) for MIDI are the main infrastructures to evolve as a fairly-featured Linux desktop audio workstation GUI, specially dedicated to the personal home-studio.
