I'm looking for a way to modify tempo or pitch of a MP3 file. Obviously i'm trying first with android clases (SoundPool, MediaPLayer, etc...) but we haven't find anything. I have tested Navigation Audio sample from NDK (using OpenSSL), but not goes in my phone. It runs but donesn't implement any effect. Any ideas?
