Question:
I'm trying to understand basic DSP stuff like changing audio playback speed. How the Playback Rate (without Preserve Pitch) works in REAPER, i.e. real-time sample rate conversion? Do you use polyphase filters or something like that? Thanks!

For that you change the samplerate, you can use anything from point sampling (very low quality), linear interpolation (slightly better but still horrible quality), to sinc interpolation (better quality). WDL has resampler.cpp which implements this.
