jack-tuner is a musical instrument tuner that uses the JACK audio connection kit. It is a command line program, and it accepts many commands. The important ones are the tone and volume commands, which can produce any audible tone from 20hz to 20khz at a volume from 0 (silence) to 1 (loudest). It can also produce notes (for example, "tone D#" produces the note D#) over several octaves (for example, "tone C octave -1" produces the note C an octave below middle-C). It can also transpose notes (for example, "tone C > 5" produces G). There are commands to do microtonal tuning too. With multiple jack-tuner instances, you can tune chords. jack-tuner does not measure the note that an instrument is playing; instead you play the desired note with jack-tuner and tune your instrument by ear.
Khronosphere is an audio recording tool. Its special feature is a buffer that keeps capturing audio even before the actual recording is started. This enables the user to prospectively catch any interesting sound that normally would have been lost. The buffer size is freely definable by the user. The software itself places no restrictions; the only limits are the resources of the host system. Khronosphere is very similar to and inspired by Jack Time Machine. They both have the same basic concept, but Khronosphere supports larger buffer sizes.
din is a software musical instrument and audio synthesizer. Bezier curves are used to draw and sculpt waveforms, create gating and modulation (FM and AM) patterns, and create delay feedback and volume patterns. You can also create an unlimited number of drones and sculpt their waveforms. It uses JACK to output audio, and supports MIDI, OSC and IRC bot for input. din can be extended and customized with Tcl scripts.
QJackRcd is a simple Qt application that records JACK server outputs. It was designed to record audio from tape, with an automatic split/pause feature. It aims to provide for simple stereo recording needs with a minimum of configuration. It natively manages silence by threshold and activation time. Silence events can be used to pause the recording or to split files. It can optionally post-process each file after recording is complete.
LinuxBand is a GUI front-end for MMA (Musical MIDI Accompaniment). Type in the chords, choose the groove, and LinuxBand will play a musical accompaniment for you. It’s an open source alternative to Band-in-a-Box featuring: an easy to use graphical interface, an open and well-documented data format, and output to JACK MIDI to facilitate co-operation with other audio applications.
