Hangs on autopeakfilter (FFT Peak-Following Filter)

[AnClark]

Hi, Jean.

I'm testing ysfx in REAPER on Linux, however it may hang on several JSFX files. For example, FFT Peak-Following Filter (autopeakfilter) shipped with REAPER (~/.config/REAPER/effects/filters/autopeakfilter).

How to reproduce this issue:

1. Add a track, load ysfx, then load "autopeakfilter"
2. Bypass ysfx
3. Load a media file into the track (WavPack, 44100Hz, 24bit integer)
4. Play
5. De-bypass ysfx, then REAPER will hang right now

My environment:

• OS: Manjaro Linux
• REAPER version: v6.66
• REAPER sound config: PulseAudio 44100Hz

I think ysfx will hang/choke eventually on all JSFX which use FFT. Including my own FFT FX & included FFT FX like "schwa/fft_splitter" . MDCT doesn't hang, but it doesn't seem to effect the audio.

It would be nice to have FFT & MDCT working in YSFX as all the interesting FX are FFT/MDCT.

Tested on:

• Windows
• Host: REAPER 6 & Studio 1 6
