I have a piece of music, and whenever it is converted (f.ex. from .ogg to .mp3) or played back by certain software, it changes to a higher pitch, and also seems to have its frequencies distorted.

What properties, or possible damage, to the sound file could be causing this to happen? How can I fix it?

  • What do you want to do with it? What file type are you starting with and what program are you converting with?

The file headers may be 1) wrong, or 2) at an uncommon bitrate/frequency that some software cannot handle.
If you can get it to transcode to wav, aif, etc at the correct pitch, I'd use that as your new 'master' version.

MediaInfo (Freeware, multi-platform) might help to figure out what the headers say - though if they are corrupted, that info in itself might not help.
Edit - I just checked, Mac v1.0 is no longer freeware, $2.99 from Mac App Store, older & other platform versions are still available, still free)

Header Investigator (Freeware, Win only) can change WAV file headers
