Hi, I'm porting Forme d'Onde Formantique (FOF) to faust. [1] [2]
It's based on [3], but can be used with dynamic parameters. [3] creates a single enveloped sine, and feeds it into a delay with full feedback, so it never changes. My version has everything synced to a master lf_rawsaw, so it continuously creates new enveloped sines. It has multiple parallel sine-envelope pairs, so the envelopes can overlap without being cut off, and you get an octaviation coefficient parameter almost 'for free' [4]. A demo song: [5]. The synth making most of the above sounds has a few problems: - It takes too much CPU when compiled with -scal, -vec or -omp. - When compiling with -sch, cc1plus eats about 13Gb of RAM/swap, and takes 7 hours. (faust 0.9.73 or faust 1 git) - Faust 2 with -sch produces a silent program. Granted, those are 256 sine-envelope pairs, so it's a miracle it runs at all! Steps to reproduce: git clone https://github.com/magnetophon/VoiceOfFaust cd VoiceOfFaust git checkout a44c5784e55f48ef44b76bac2e628e7a941e2474 time /home/bart/.nix-profile/bin/faust2jack -t 99999 -time -osc -sch FOFvocoder.dsp ./FOFvocoder & sleep 2 && jack_connect system:capture_1 FOFvocoder:in_0 & jack_connect FOFvocoder:out_0 system:playback_1 & jack_connect FOFvocoder:out_1 system:playback_2 To use it as intended, you also have to run: pd PureData/OscSendVoc.pd Cheers, Bart.
