Pitching MP3 (Not PitchShift!) is possible since Flash10s new Sound API. Today I saw Lee Brimelow’s post about doing so, providing some source code. Cause we spend a lot of time to keep things running more smoothly in the AudioTool, I created another version which has some advantages.
- No objects are created in runtime (memory usage)
- The SampleDataEvent is receiving a static blocksize (steady latency)
- Linear interpolation (sound quality)
- Speed can go down to zero
