Lee Brimelow and Andre Michelle got together this week to actually do something we've only hypothesized about: enabling pitch-shift in Flash. We talked about it - they did it. I'm completely in awe... THANK YOU!!

(theflashblog.com) This is an extension of the example that can be found in the documentation for the Sound.extract method. Now this example does adjust the pitch but it also speeds the song up as well. This is because you need to skip some samples in order to increase the pitch. Now there are ways to increase the pitch of sounds without speeding them up but I have no idea how to do it. Do you?

(blog.andre-michelle.com) 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 with 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
