Debian Multimedia Mixing packages

Ardour is a multichannel hard disk recorder (HDR) and digital audio workstation (DAW). It can be used to control, record, edit and run complex audio setups.

Ardour supports pro-audio interfaces through the ALSA project, which provides high quality, well designed device drivers and API's for audio I/O under Linux. Any interface supported by ALSA can be used with Ardour. This includes the all-digital 26 channel RME Hammerfall, the Midiman Delta 1010 and many others.

Ardour has support for 24 bit samples using floating point internally, non-linear editing with unlimited undo, a user-configurable mixer, MTC master/slave capabilities, MIDI hardware control surface compatibility.

It supports MIDI Machine Control, and so can be controlled from any MMC controller and many modern digital mixers.

Ardour contains a powerful multitrack audio editor/arranger that is completely non-destructive and capable of all standard non-linear editing operations (insert, replace, delete, move, trim, select, cut/copy/paste). The editor has unlimited undo/redo capabilities and can save independent "versions" of a track or an entire piece

Ardour's editor supports the community-developed LADSPA plugin standard. Arbitrary chains of plugins can be attached to any portion of a track. Every mixer strip can have any number of inputs and outputs, not just mono, stereo or 5.1. An N-way panner is included, with support for various panning models. Pre- and post-fader sends exist, each with their own gain and pan controls. Every mixer strip acts as its own bus, and thus the bus count in Ardour is unlimited. You can submix any number of strips into another strip.

Ardour's channel capacity is limited only by the number on your audio interface and the ability of your disk subsystem to stream the data back and forth.

JACK (the JACK Audio Connection Kit) is used for all audio I/O, permitting data to be exchanged in perfect samplesync with other applications and/or hardware audio interfaces.

Ardour is sample rate and size neutral - any hardware formats from 8 to 32 bits, and rates from 8kHz to 192kHz. Internal processing in 32/64 bit IEEE floating point format.

aubio gathers a set of functions for audio signal segmentation and labelling. The library contains a phase vocoder, onset and pitch detection functions, a beat tracking algorithm and other sound processing utilities.

This package provides command line tools to run the different algorithms.

Audacity 是一个针对 Linux/Unix、 MacOS 及 Windows 平台的多音轨音频编辑器。 它是为方便用户录制、播放和编辑数字音频而设计的。Audacity 带有数码特效和频谱分析 工具。操作便捷并支持无限次撤消和重做。

它支持的文件格式包括 Ogg、Vorbis、MP2、MP3、WAV、AIFF 和 AU 等。

These tools help controlling loudness of audio material aimed primarily for broadcasting, but they can be useful in other situation.

ebumeter and ebur128 allow users to measure Momentary (400 ms), Short term (3s) and Integrated Loudness (from start to stop). They can be used on audio files and signals through JACK.

This package contains two programs:

• ebumeter - interactive meter working via jackd
• ebur128 - the command line app to measure sound files

The Gtk Wave Cleaner (gwc) is an application that helps you in getting rid of noise and clicks in audio files. This is most commonly used when translating your old vinyl or old tapes to a digital format, but it can be applied to every soundfile that has a more or less constant noise level.

Jaaa (JACK and ALSA Audio Analyser) is an audio signal generator and spectrum analyser designed to make accurate measurements.

Jaaa allows you select on of the four inputs, 'Min' and 'Max' the min and max displayed frequencies. There can be up to two markers which helps accurately read off values in the display.

Jack Audio Mixer provides a GTK+ GUI to mix JACK audio streams. It maintains the appearance of a hardware audio mixing desk. It can set levels, balance, mute, etc through the interface or via MIDI.

This package installs the application for Python 3.

Japa, is a 'perceptual' or 'psychoacoustic' audio spectrum analyser. Possible uses include spectrum monitoring while mixing or mastering, evaluation of ambient noise, and (using pink noise) equalisation of PA systems.

It supports up to four audio inputs of which two can graphically be compared. Additionally a pink noise and white noise generator is running after starting japa.

A jkmeter displays both the true RMS level and the digital peak level. But can display stereo correlation too.

Jkmeter is based on the ideas of mastering guru Bob Katz. See https://www.digido.com/bob-katz/index.php and follow the links on 'level practices'. This is the type of meter you want for live recording, mixing and mastering

A jmeters is multichannel audio level meter for Jack Audio Connection Kit. It uses the same pixmaps as meterbridge. The main difference to meterbridge is that jmeters has the correct ballistics for both the VU and the PPM.

A jnoisemeter is a small app designed to measure audio test signals and in particular noise signals.

The simplest use is to measure the S/N ratio of your sound card. If you can calibrate the input levels of your soundcard it can also be used (with some external hardware) to measure noise levels of any type of audio equipment, including preamps and microphones.

SoX is the swiss army knife of sound processing.

This is a metapackage depending on all free SoX format libraries.

Meterbridge implements various meters for the JACK Audio Connection Kit. Examples of the available types are:

• PPM Peak Program level Meter
• VU Volume Unit Meter
• DPM Digital Peak Meter
• JF Jellyfish Meter
• SCO Scope

VLevel keeps your music from making you jump out of your seat, and it keeps you from having to fiddle with the volume constantly. It's different from other dynamic compressors because it looks ahead. You can think of VLevel as someone who knows your music by heart, and turns the volume up during quiet passages, but smoothly turns it back down when he knows a loud part is coming. It's great for making CDs to listen to in your car, or to play background music on your computer.

VLevel is currently a LADSPA plugin, a JACK plugin and a command-line filter. You can use it with many Linux audio programs including XMMS, GStreamer, GLAME, GDAM, and others, and you can use it in shell scripts to level your music before burning a CD.

The commandline filter is also useful for levelling podcasts before (encoding and) publishing.

Allows toggling record source, muting individual channels, adjusting volume and balance, all in a compact dockapp size, with TV-like on-screen-display for volume levels.

Supports mousewheel to adjust current channelvolume and can be controlled remotely with SIGUSR1 / SIGUSR2 to adjust the volume. Keeps a simple configuration file for user-defined settings.

Brp-pacu compares the output of the system to the input of the system and allows you to use this data to perform final equalization by matching the results with actual DSP/EQ.

JAM is a tool for producing audio masters from a mixed down multitrack source. It runs in the JACK Audio Connection Kit, and uses LADSPA for its backend DSP work, specifically the swh plugins created by Steve Harris, JAM's main author.

• Linear filters
• JACK I/O
• 30 band graphic EQ
• 1023 band hand drawn EQ with parametric controls
• Spectrum analyser
• 3 band peak compressor
• Lookahead brickwall limiter
• Multiband stereo processing
• Presets and scenes
• Loudness maximiser

mhWaveEdit is a graphical program for editing sound files. It is intended to be user-friendly and robust. It does not require a fast computer.

Supports JACK, ALSA, OSS and PulseAudio.

Nama is a text-based application for multitrack recording, mixing and mastering using the Ecasound audio engine developed by Kai Vehmanen.

Features include tracks, buses, effects, presets, sends, inserts, marks and regions. Nama runs under JACK and ALSA audio frameworks, automatically detects LADSPA plugins, and supports Ladish Level 1 session handling.

All editing under Nama is non-destructive. Effects are generally applied in realtime. A track caching (track freezing) function is also available.

The command prompt accepts Nama commands, Ecasound interactive-mode commands, shell commands and perl code, providing command history and autocompletion. The help system covers internal commands and LADSPA effects and includes keyword search.

By default, Nama displays a simple graphic interface while the command processor runs in a terminal window. The -t option provides a text-only interface for console users.

PNMixer is a simple mixer application designed to run in your system tray. It integrates nicely into desktop environments that don't have a panel that supports applets and therefore can't run a mixer applet. In particular it's been used quite a lot with fbpanel and tint2, but should run fine in any system tray.

PNMixer is designed to work on systems that use ALSA for sound management. Any other sound driver like OSS or FFADO, or sound server like PulseAudio or Jack, are currently not supported (patches welcome).

Silan is a standalone application to analyze audio files for silence and print ranges of detected signals.

It supports a variety of audio-formats and codecs by making use of libsndfile and ffmpeg/libav for reading audio-data.

Signal threshold and hold-off time can be freely configured. The output can be formatted with samples or seconds as unit or printed as audacity label file.

The aim of Sonic Visualiser is to be the first program you reach for when want to study a musical recording rather than simply listen to it.

Sonic Visualiser could be of particular interest to musicologists, archivists, signal-processing researchers and anyone else looking for a friendly way to take a look at what lies inside the audio file.

SoundConverter 是一个 GNOME 应用程序。它可以读取各种 GStreamer 支持的音频格式，然后转换成 Ogg Vorbis、FLAC、WAV 等格式。如果您安 装了 LAME 插件，还可以转换成 MP3 格式。

SoX is a command line utility that can convert various formats of computer audio files in to other formats. It can also apply various effects to these sound files during the conversion. As an added bonus, SoX can play and record audio files on several unix-style platforms.

SoX is able to handle formats like Ogg Vorbis, MP3, WAV, AIFF, VOC, SND, AU, GSM and several more. Any format support requires at least libsox-fmt-base. Some formats have their own package e.g. mp3 read and write support is provided by libsox-fmt-mp3.

SoX supports most common sound architectures i.e. Alsa, Libao, OSS and Pulse (respectively provided by libsox-fmt-alsa, libsox-fmt-ao, libsox-fmt-oss and libsox-fmt-pulse). It also supports LADSPA plugins.

pyMapperGUI is a Graphical User Interface for libmapper

libmapper is a cross-platform software library for declaring data signals on a shared network and enabling arbitrary connections to be made between them. It creates a distributed mapping system/network, with no central points of failure, the potential for tight collaboration and easy parallelization of media synthesis.

The Non DAW Studio is a modular system composed of four main parts consisting of the Non Timeline, the Non Mixer, the Non Sequencer, and the Non Session Manager.

The No DAW Studio is a complete studio that is fast and light enough to run on low-end hardware.

This is the Non Mixer package.

Your workflow becomes easy to manage, robust and fast by leveraging the full potential of cooperative applications.

It is a community version of the "NON Session Manager" and free in every sense of the word.

You can create a session, or project, add programs to it and then use commands to save, start/stop, hide/show all programs at once, or individually. At a later date you can then re-open the session and continue where you left off.

RaySession is a GNU/Linux session manager for audio programs such as Ardour, Carla, QTractor, Patroneo etc... The principle is to load together audio programs, then be able to save or close all documents together. It communicates with programs using the Non Session Manager API, so programs compatible with NSM are also compatible with RaySession.

An integrated client can save and restore JACK connections. Except this, RaySession doesn't deals with JACK, the recommended user behavior is to use it when JACK is already started.
