NeuralRack is a Neural Model and Impulse Response File loader for Linux/Windows. 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… This release introduce a modernised UX. ![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.

Sonivox Synthesizer Library v3.6.16 has been released

by Pedro Lopez-Cabanillas

This project is a fork of the Android Open Source Project 'platform_external_sonivox', including a CMake based build system to be used not on Android, but on any other computer Operating System. Google licensed this work originally named Sonivox EAS (Embedded Audio Synthesis) from the company Sonic Network Inc. under the terms of the Apache License 2.0. Here is the Google source code repository: https://android.googlesource.com/platform/external/sonivox.git This is a "wavetable" synthesizer, not using external soundfont files by default but embedded samples instead. DLS files are also supported. It is also a MIDI file player and a real time GM synthesizer. It consumes very little resources, so it may be indicated in projects for small embedded devices. There is neither MIDI input nor audio output facilities included in the library. You need to provide your own input/output. Changes in v3.6.16 * Fix bswap use on Android by @lephilousophe in #33 * Add templates and guidelines by @pedrolcl in #34 * Improve test dls downloading by @rsp4jack in #37 * Implement a-law/u-law wave format decoding for dls by @SmithGoll in #40 * Fix logic error in loop boundary check by @SmithGoll in #42 * Addition fix of #37: fix SonivoxTestEnvironment getTmp() by @rsp4jack in #44 * Implement WAVE_FORMAT_MPEGLAYER3 decoding for dls by @SmithGoll in #47 * Add new workflow action for android by @pedrolcl in #48 * Rescue commented logging calls by @rsp4jack in #45 * Selectable verbosity level by @pedrolcl in #50 Project page: https://github.com/pedrolcl/sonivox Downloads: https://github.com/pedrolcl/sonivox/releases/tag/v3.6.16 License: Apache 2.0

rtcqs v0.6.6 released

by Jeremy Jongepier

Dear all, rtcqs is a Python utility to analyze your system and detect possible bottlenecks that could have a negative impact on the performance of your system when working with Linux audio. rtcqs v0.6.6 is now available. Latest release that was announced on this list was v0.5.2. Notable changes since v0.5.2 include: - Added SMT check - Replaced audio group check with a group agnostic check - Governor check can now deal with systems that have SMT disabled - Tickless check now deals with all CONFIG_NO_HZ* variants and with nohz being set on the kernel command line - File systems check has been expanded - IRQ check now loops through /sys/kernel/irq instead of parsing /proc/interrupts - rtprio check now checks if a SCHED_FIFO priority can be set instead of a SCHED_RR priority - Improved preempt RT check, check if “preempt=full” is part of the kernel command line For information on getting the latest version see https://codeberg.org/rtcqs/rtcqs. Best, Jeremy

Qtractor 1.5.4 - An Early Spring'25 Release

by Rui Nuno Capela

Hi everyone, Qtractor 1.5.4 (early-spring'25) released! Change-log: - Fixed non-zero clip offset conversion on tempo(BPM) time-scale changes. - MIDI clip step input and overdubbing now aggregated and fully undo/redo-able. - Allow MIDI step input to extend the clip length automatically; also avoid step input event duplicates (eg. playing chords in quick succession) leading to potential double-free segfault or crash. - Fixed MIDI track state when clips under record/overdubbing are simply removed. - Fixed all empty/void audio clips that are created when aborting an armed recording session. - MIDI clip editor (aka. piano-roll): simply allow a MIDI track to be a ghost of itself. - In addition to clips and markers, automation curves and tempo-map nodes now also contribute to the total session length and status. - Fixed command line parsing (QCommandLineParser/Option) to not exiting the application with a segfault when showing help and version information. 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.
