I found another interesting audio #plugin for #Linux: #reTuner claims to do good pitch-shifting for instruments generally too low or too high. Like 440Hz to 432Hz shifting.

There is a .deb package, yet unfortunately, the plugin installs to a non-standard place.

I decided to symlink /usr/lib/x86_64-linux-gnu/vst3/KV-reTuner.vst3 to /usr/lib/vst3 instead of adjusting plugin paths in all my plugin hosts.

I don't have an urgent need for it, but I'm sure I will use this at some point.

(Actually I am looking for a possible replacement of the pitch shifter in my Lexicon MX200, which I still do love… yet the ADCs of the Lexicon are a sad story, and the old Boss compressor sitting in that rack together with a cheap Alesis tube preamp isn't that reliable any more.)

🧵 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.

@nielso I'm looking for decent (monophonic) pitchshifting on linux as well. I found this to sound very good in a musical context, but quite CPU intensive.
