python-pysox is a wrapper around the sox command line tool. The API offers Transformer and Combiner classes that allow the user to incrementally build up effects and audio manipulations. python-pysox also provides methods for querying audio information such as sample rate, determining whether an audio file is silent, and much more.

This package provides a header-only version of the HIIR library by Laurent De Soras, updated to version 1.40. HIIR is a C++ library for changing the sampling rate of a signal by a factor two, in both directions (upsampling and downsampling), obtaining two signals with a π/2 phase difference (Hilbert transform). It is made of a two-path polyphase IIR filter, implemented with FPU, 3DNow!, SSE, SSE2, AVX, AVX-512 and NEON instruction sets.

This package contains the same as the original library, except with the contents of one source file moved into a header file (and set as inline) to make the library header-only, and with the test folder removed.

yabridgectl is a tool to setup and update yabridge.

Dexed is a multi-platform, multi-format plugin synthesizer. The sound engine is closely modeled on the original Yamaha DX7 characteristics. Dexed is also a MIDI cartridge librarian/manager for the DX7. Features include:

1. 144 DAW automatable DX7 parameters available from one single panel;

2. It fully supports DX7 input and output Sysex messages; including controller change. This means that you can use this with a native DX7/TX7 as a patch editor and sysex manager.

3. Every FM operator has a realtime VU meter to know which one is active.

4. It can load/save any DX7/TX7 sysex programs. It is also possible to save a single program into a different sysex file.

Dexed can be configured to use some of the original math limitation of a DX synthesizer. This does not only apply to the DAC, it also involves the bit resolution of the sine waves and the way that the amplitude is applied to each operator. Dexed comes with three engine types:

1. Modern: this is the original 24-bit implementation.

2. Mark I: Based on the OPL Series but at a higher resolution (LUT are 10-bits). The target of this engine is to be closest to the real DX7.

3. OPL Series: this is an experimental 8-bit implementation of the reversed engineered OPL family chips.

libmt32emu is a C/C++ library which approximately emulates the Roland MT-32, CM-32L and LAPC-I synthesizer modules. It is part of the Munt project.

The SoX Resampler library (libsoxr) performs one-dimensional sample-rate conversion. It may be used, for example, to resample PCM-encoded audio.

midicomp can manipulate SMF (Standard MIDI File) files. It can both read and write SMF files in 0 or format 1 and also read and write its own plain text format. This means a SMF file can be turned into easily parseable text, edited with any text editor or filtered through any script language, and recompiled back into a binary SMF file.

TinyALSA is a small library to interface with ALSA in the Linux kernel.

This package provides a barebones, fast LV2 bass enhancement plugin.

DRC is a program used to generate correction filters for acoustic compensation of HiFi and audio systems in general, including listening room compensation. DRC generates just the FIR correction filters, which can be used with a real time or offline convolver to provide real time or offline correction. DRC doesn't provide convolution features, and provides only some simplified, although really accurate, measuring tools.

Libzita-resampler is a C++ library for resampling audio signals. It is designed to be used within a real-time processing context, to be fast, and to provide high-quality sample rate conversion.

Python API for Spatially Oriented Format for Acoustics files as specified in SOFA conventions.

Sratom is a library for serialising LV2 atoms to/from RDF, particularly the Turtle syntax.

LV2 port of CAPS, a collection of audio plugins comprising basic virtual guitar amplification and a small range of classic effects, signal processors and generators of mostly elementary and occasionally exotic nature.

The Bauer stereophonic-to-binaural DSP (bs2b) library and plugins is designed to improve headphone listening of stereo audio records. Recommended for headphone prolonged listening to disable superstereo fatigue without essential distortions. This package contains a LADSPA plugin for use with applications that support them (e.g. PulseAudio).

RtMidi is a set of C++ classes (RtMidiIn, RtMidiOut, and API specific classes) that provide a common cross-platform API for realtime MIDI input/output.

RaySession is a session manager for audio programs such as Ardour, Carla, QTractor, Guitarix, Patroneo, Jack Mixer, etc. The principle is to load together audio programs, then be able to save or close all documents together. Its main purpose is to manage NSM compatible programs, but it also helps for other programs. It offers a patchbay for visualizing and editing connections.

shntool is a multi-purpose WAVE data processing and reporting utility. File formats are abstracted from its core, so it can process any file that contains WAVE data, compressed or not---provided there exists a format module to handle that particular file type. It can also generate CUE files, and use them split WAVE data into multiple files.

QJackRcd is a simple graphical stereo recorder for JACK supporting silence processing for automatic pause, file splitting, and background file post-processing.

liblo is a lightweight library that provides an easy to use implementation of the Open Sound Control (OSC) protocol.

LADSPA is a standard that allows software audio processors and effects to be plugged into a wide range of audio synthesis and recording packages.

This C library provides an encoder and a decoder for the GSM 06.10 RPE-LTP lossy speech compression algorithm.

XJackFreak is an audio analysis and equalizing tool for the Jack Audio Connection Kit. It can display the FFT of any input, modify it and output the result.

The Odio SACD shared library is a decoding engine which takes a Super Audio CD source and extracts a 24-bit high resolution WAV file. It handles both DST and DSD streams.
