  <p>you know where to begin to change the audio stream with different filters? as Voices2 app. I can store and play audio files, but I have no idea how to filter the sound. I know that I have to start from Core Audio, but I do not know exactly where to direct me. Do you know if there are tutorials, or mac app that help?
  Thank you!</p>
