Can't set "audio-bufsize" #41

Closed frans-fuerst closed 1 year ago

frans-fuerst commented 1 year ago

Via fluidsynth command line you can set the audio buffer size via -z or --audio-bufsize. For some strage reason I need to set it on Fedora 36+ to get non-chopped output. However there seems to be no way to set this value using Synth.settings. Despite those look somehow generic, there was no way to set it the setting() function I tried: audio.bufsize, audio.buffer-size audio.buf-size, synth.bufsize, synth.buf-size, synth.audio-bufsize and some more without success. Is there a way to workaround this?

I'm using pyFluidSynth v1.3.1 fluidsynth v2.3.1 on Python 3.10

Ok, found it - was just bad naming inside fluidsynth itself - while the command line option is called --audio-bufsize the actual internal parameter is called audio.period-size. Setting this works for me.

Hi, just briefly looking into this, I was not able to find the audio buffer size anywhere in the libfluidsynth docs page: https://www.fluidsynth.org/api/settings_synth.html Maybe there's a difference between synthesizer and audio settings? Chris
