Microtones Library
Microtonal Music Notation and Playback for Sibelius, Kontakt, UVI, Max
This open-source plugin suite aims at extending Sibelius to allow it to handle microtonal music (up to the eighth-tone) and play it back with various synthesizers (currently Kontakt 5, UVI station and Max/MSP). This library offers among others the following features: − insertion of microtones in the music − transposition using microtonal intervals − precise polyphonic playback of microtonal music with Kontakt and Max/MSP, without the requirement for pitch bends (the standard playback system of Sibelius is limited to monodies, and its use of pitch bends entails undesired pitch glitches in the rendering) − handling of microtonal scales, build scales, check if the music material belongs to a given scale, warping from one scale to another one, transpose notes to the closest member of a microtonal scale, etc. − handling of microtonal artificial harmonics and microtonal glissandi The development of this library has been commissioned by the CIRM studios, Nice, France -

livemix
A tool for automated downmixing of live multitrack sound recordings
Livemix will search directory tree for audio files, assuming each of them is a separate track, then group them into sessions based on file size, and then create a downmix for each session. Silent tracks are ignored, the others are processed by applying some effects such as compand, then normalized and then combined into downmix with equal volume. Sessions are named by the time of recording in YYYYMMDD-HHMMSS format. Intended use is to quickly generate mp3 previews of live multitrack music recordings (such as rehearsals or live performances), created by some sound recording software (Avid ProTools or Audacity for example). Livemix uses SoX sound processing utity to do all the work with tracks preprocessing and mixing, and LAME mp3 encoder to produce final mp3 file. Therefore, livemix needs sox and lame executables to be in search path or in the same dir as livemix executable. -
