Pulsemixer is a PulseAudio mixer with command-line and curses-style interfaces.

paprefs is a simple GTK based configuration dialog for the PulseAudio sound server. Note that this program can only configure local servers, and requires that a special module module-gsettings is loaded in the sound server.

Libsndfile is a C library for reading and writing files containing sampled sound (such as MS Windows WAV and the Apple/SGI AIFF format) through one standard library interface.

It was designed to handle both little-endian (such as WAV) and big-endian (such as AIFF) data, and to compile and run correctly on little-endian (such as Intel and DEC/Compaq Alpha) processor systems as well as big-endian processor systems such as Motorola 68k, Power PC, MIPS and SPARC. Hopefully the design of the library will also make it easy to extend for reading and writing new sound file formats.

Secret Rabbit Code (aka. libsamplerate) is a Sample Rate Converter for audio. One example of where such a thing would be useful is converting audio from the CD sample rate of 44.1kHz to the 48kHz sample rate used by DAT players.

SRC is capable of arbitrary and time varying conversions; from downsampling by a factor of 256 to upsampling by the same factor. Arbitrary in this case means that the ratio of input and output sample rates can be an irrational number. The conversion ratio can also vary with time for speeding up and slowing down effects.

SRC provides a small set of converters to allow quality to be traded off against computation cost. The current best converter provides a signal-to-noise ratio of 145dB with -3dB passband extending from DC to 96% of the theoretical best bandwidth for a given pair of input and output sample rates.

PulseAudio is a sound server. It is basically a proxy for your sound applications. It allows you to do advanced operations on your sound data as it passes between your application and your hardware. Things like transferring the audio to a different machine, changing the sample format or channel count and mixing several sounds into one are easily achieved using a sound server.

NoiseTorch creates a virtual PulseAudio microphone that suppresses noise, in any application. Use whichever conferencing or VOIP application you like and simply select the NoiseTorch Virtual Microphone as input to torch the sound of your mechanical keyboard, computer fans, trains and the likes.

PulseAudio Volume Control (pavucontrol) provides a GTK+ graphical user interface to connect to a PulseAudio server and easily control the volume of all clients, sinks, etc.

Ponymix is a PulseAudio mixer and volume controller with a command-line interface. In addition, it is possible to use named sources and sinks.

pamixer is like amixer but for PulseAudio, allowing easy control of the volume levels of the sinks (get, set, decrease, increase, toggle mute, etc).

pasystray enables control of various PulseAudio server settings from the X11 system tray. See the project README.md for a detailed list of features.

Apulse provides an alternative partial implementation of the PulseAudio API. It consists of a loader script and a number of shared libraries with the same names as from original PulseAudio, so applications could dynamically load them and think they are talking to PulseAudio.

Internally, no separate sound mixing daemon is used. Instead, apulse relies on ALSA's dmix, dsnoop, and plug plugins to handle multiple sound sources and capture streams running at the same time. dmix plugin muxes multiple playback streams; dsnoop plugin allow multiple applications to capture from a single microphone; and plug plugin transparently converts audio between various sample formats, sample rates and channel numbers.

This plug-in is meant to suppress a wide range of noise origins: computer fans, offices, crowds, airplanes, cars, trains, construction, and more.

Mild background noise is always suppressed, loud sounds, like clicking of mechanical keyboard, are suppressed while there is no voice however they are only reduced in volume when voice is present.

The plug-in is made to work with 1 or 2 channels (LADSPA plugin), 16 bit, 48000 Hz audio input.

Pumpa is a simple pump.io client written in C++ and Qt.

Purescript is a small strongly, statically typed programming language with expressive types, inspired by Haskell and compiling to JavaScript.

pv is a terminal tool for monitoring the progress of data through a pipeline. It can be inserted into any normal pipeline between two processes. It gives a visual indication of how quickly data is passing through, how much has been transferred and how near to completion it is (with a progress bar), how long it has taken, and an estimate of the remaining time before completion.

PyPy is a faster, alternative implementation of the Python programming language employing a just-in-time compiler. It supports most Python code natively, including C extensions.

This package provides a PEP 518 build backend that uses setuptools_scm to generate a version file from your version control system, then flit_core to build the package.

Setuptools is a fully-featured, stable library designed to facilitate packaging Python projects, where packaging includes:

• Python package and module definitions

• distribution package metadata

• test hooks

• project installation

• platform-specific details.

Setuptools_scm handles managing your Python package versions in software configuration management (SCM) metadata instead of declaring them as the version argument or in a SCM managed file.

Hatch is a modern, extensible Python project manager. It has features such as:

• Standardized build system with reproducible builds by default

• Robust environment management with support for custom scripts

• Easy publishing to PyPI or other indexes

• Version management

• Configurable project generation with sane defaults

• Responsive CLI, ~2-3x faster than equivalent tools.

The build command invokes the PEP 517 hooks to build a distribution package. It is a simple build tool and does not perform any dependency management. It aims to keep dependencies to a minimum, in order to make bootstrapping easier.

Python Build Reasonableness (PBR) is a library that injects some useful and sensible default behaviors into your setuptools run. It will set versions, process requirements files and generate AUTHORS and ChangeLog file from git information.
