Is there any software out there to add subtle realistic pitch variation to bounced audio files? Most of synthesizers and audio plugins let you do something like this. Unfortunately they don't sound realistic and they're linear somehow. Things like adding LFOs even with incompatible phase would not help that much in creating subtle realistic pitch variations.

  • May I enquire as to why you are doing this? Sounds like you are going to be adding wow-and-flutter etc which is a vinyl artifact. Generally at the mix/bounce level this is something you want to remove, not add. Can you clarify what you are trying to achieve? – Mark Nov 11 at 6:59
  • @Mark Because it adds interest, texture and realness to the raw, dull synthesized sound or sample. It adds variation to a sample if used several times. – FreeMind Nov 11 at 10:03
  • ....but also introduces issues with intonation and harmonization. If you are intending to add texture then I would recommend you look at effects such as modulation, delay, reverb and convolution rather than altering pitch. If you are looking for organic ways to modify some effect parameters generally, then you can use a midi controller to generate automation tracks that will allow you to automatically modify these parameters across the length of the mix. – Mark Nov 11 at 10:11
  • @Mark Well it still will lack something if you automate stuff like that. Pitch variation is unavoidable and happens in real instruments. The most important thing is that resonant pitch variation at the tail of instruments notes which does not happen on Synthesizers(At least most of them) like that ringing tail which varies in pitch and makes your composition sound authentic. – FreeMind Nov 11 at 10:14
  • There's no component of reverberation that changes the pitch of a sound as far as I am aware. Do you have an example you can share? – Mark Nov 11 at 10:48
