“Paraphrasis is an Open Source spectral resynthesis synthesizer which can model any sound with only one sonic sample. It is based on modified Loris – an Open Source sound modeling and processing software package – and JUCE.
Only two parameters are needed:
- frequency pitch of a sample.
- frequency resolution of spectral analysis.
Paraphrasis has a 16 voice polyphony and has a “Reverse” option to analyse the sample backward so it is synthesised reversed as well.
Note: Currently only mono sounds can be handled – the stereo input is automatically converted into mono.”
