🧵 So, on my journey to live #PitchShift on #Linux with an #audio #plugin, I found #SpectralShift. This one is very good I think. However, it has too much latency for live use, so it's more for mixdown.
The old #MaPitchshift serves as an example for one of the reasons why #LinuxProAudio had a bad reputation in the past: It's practically useless. It does pitch shifting, but it only shifts by some magic floating point number which has no easy-to-handle relation to musical terms such as semitones or cents. The latency depends on the window setting, yet it is possible to sabotage the thing completely by nonsensical settings.
So I asked ChatGPT and it said the ratio is 2^(Semitones/12) – keep this in mind and your calculator ready. 🤪 This is actually sort of correct.
Turns out that the shifting of #MaPitchshift is too inacurate for musical use with a window size suitable for live use. So, giving up for now, back to outboard, my 21-year-old #Lexicon #MX200 is way better.
