“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. It was developed as entry for KVRAudio developer challenge 2014.
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. You can check sources at github or current and previous releases at archive.”
