MASS is Music and Audio in Sample Sequences
This project delivers routines for music oriented sound synthesis in a sample based system. MASS can be though of as a sample level DAW system, in which the objects manipulated are in fact the array of samples describing the sound wave that will reach a listener ear.
$ pip3 install music
(sorry, mass package was already take :O2)
Real time is possible but not the emphasis: all parameters are updated sample by sample and calculations are made in 64 bit floating point. All operations are described by equations that directly relates audio samples to musical aspects. Detailed descriptions can be found in:
- the article “Psychophysics of musical elements in the discrete-time representation of sound”: http://arxiv.org/abs/1412.6853
- the msc dissertation “Música no áudio digital: descrição psicofísica e caixa de ferramentas”: https://github.com/ttm/dissertacao/blob/master/dissertacaoCorrigida.pdf?raw=true
