- Think of a radio station. Airtime is software that allows multiple people to run it over the internet. Airtime helps them manage the audio archive, upload files, create shows, manage staff, edit the programme calendar and cue playout. Designed specifically for independent media, it's free software.
- Ardour is a professional multitrack/multichannel audio recorder and DAW for GNU/Linux, using ALSA-supported audio interfaces. It supports up to 32 bit samples, 24+ channels at up to 96kHz, full MMC control, a non-destructive, non-linear editor, and LADSPA plugins.
- Audacity is a cross-platform multitrack audio editor that lets you record sounds directly or import Ogg, WAV, AIFF, AU, IRCAM, or MP3 files. It features a few simple effects, all of the editing features you should need, and unlimited undo. The GUI is built with wxWidgets and the audio I/O currently uses PortAudio.
- CYTHAR is multi-platform, pattern-oriented, polyphonic MIDI step-sequencer, which makes its own path. 16 parallel patterns with six tracks and 16 bars -- equating to 256 bars and 96 tracks. The six pattern tracks imitate the strings of a guitar and will be tuned e.g. to “EAdgbe”. For example, you can set a guitar chord to a pattern tune and then by enabling a few events or triggers the sequencer will start a solo or plays with the chords. You can program drum sets, melodies, arpeggios and complete songs.
- Command-line tools for audio playback, processing, and whatever else related to audio. dtas follows the worse-is-better philosophy and acts as duct tape to combine existing command-line tools for flexibility and ease-of-development. dtas is currently implemented in Ruby (and some embedded shell), but may use other languages in the future. Currently, primarily wraps sox commands but may also use ecasound (or any command-line driven audio processing tools).
- Ecasound is a software package designed for multitrack audio processing. It can be used for simple tasks like audio playback, recording and format conversions, as well as for multitrack effect processing, mixing, recording and signal recycling. Ecasound supports a wide range of audio inputs, outputs and effect algorithms. Effects and audio objects can be combined in various ways, and their parameters can be controlled by operator objects like oscillators and MIDI-CCs. A versatile console mode user-interface is included in the package.
- FFmpeg is a complete solution to record, convert and stream audio and video.
Its components include:
- ffmpeg – Converts one video file format to another and supports grabbing and encoding in real time from a TV card.
- ffserver – HTTP (RTSP is being developed) multimedia streaming server for live broadcasts that supports time shifting.
- ffplay – simple media player based on SDL and the ffmpeg libraries
- ffprobe – a media file prober
- libavcodec – library containing all FFmpeg audio/video encoders and decoders (most developed from scratch for best performances and high reusability)
- libavfilter – video and audio filtering library
- libavformat – library of parsers and generators for all common audio/video formats
- libavutil – utility library containing functions used by all FFmpeg components
- libswscale – video scaler and pixel format converter
- libswresample – audio resampler and sample format converter
- libpostproc – video post-processing library
- Advanced GTK+ Sequencer (AGS) is intended to use for music composition. It features a piano roll, as well a synth, matrix editor, drum machine, soundfont2 player, mixer and an output panel. Further it has LADSPA, DSSI and Lv2 plugin support. It's designed to be highly configurable. You may add effects to its effect chain; and add or remove audio channels/pads. You may set up a fully functional network of engines, thus there is a link editor for linking audio lines. AGS requires a realtime kernel and ALSA support. AGS uses conditional locks to keep several threads in sync that's why you need at least a preemptable kernel. LADSPA support has been added to version 0.4.2 as well export to WAV. Version 0.5.x brings you first concurrent audio tree processing support. Version 0.6.x is dedicated to accessibility. You might control GSequencer by keyboard. As you move to a note it provides you an audible feedback. Version 0.7.x gives you the benefit of providing the libraries libags, libags-thread, libags-server, libags-audio and libgsequencer. It contains for now an automation editor. Open Sound System (OSS4) and JACK Audio Connection Kit support has been added recently. Now you may configure multiple soundcards. Since 0.7.111 there is MIDI input available. Let you record your MIDI instrument and doing live performance. Version 0.8.x extended MIDI support to import/export SMF. A built-in envelope editor and additional editing functionality like move/crop selected notes. Version 0.9.x added automation editor. Version 1.0.x released implemented sticky controls. Version 1.1.x segmented AgsNotation and AgsAutomation. Version 1.2.x improved audio backend support and improved accessibility by using Atk+ interfaces. Migrated to segmented AgsNotation , Version 1.3.x migrated to segmented AgsAutomation. Version 1.4.x AgsWave and AgsBuffer have arrived in libags_audio.so Version 2.0.x provides new machines AgsEqualizer10, AgsSpectrometer and AgsAudiorec. Wave form manipulation and recording capabilities. Version 2.1.x has got initial OSC content model support. The provided OSC server allows you to do remote control. Version 2.2.x support for GCC builtin vector functions and added complex data type support. Version 2.3.x added new machines AgsFMSynth, AgsFMSyncsynth and AgsPitchSampler. Support for WASAPI. Version 3.0.x added GObject-Introspection annotations. Implemented AgsServer providing basic HTTP authentication using XMLRPC library libsoup-2.4. Added online help browser to view the user manual within UI by using WebKit2Gtk-4.0. Further providing support for AGS-OSC-OVER-XMLRPC and migrated to Gtk-3. Allow the user to perform fast export to audio file with AgsAudiorec. Version 3.3.x provides a new effect processors, the ags-fx engine. All recalls have got a replacement in order to operate with one single iteration per tic. Further the staging program is modifiable. Version 3.4.x implemented AgsSFZSynthGenerator and AgsSF2SynthGenerator allowing you to pitch missing samples. Version 3.6.x implemented AgsGstreamerFile capable of reading common media files using gstreamer. Version 3.12.x implemented composite editor. Version 4.0.x migrated to Gtk4 and libsoup-3.0. Version 4.1.x implemented zoom in PDF manual. Version 5.0.x improved vst3 api reference manual. Version 5.2.x implemented tremolo, vibrato and wah-wah of SFZ and Soundfont2 synths. Version 5.4.x fixed automation editor.
