I'm searching for delphi firemonkey expert in audio-video programming, to optimize my software for MAC OS X. The software is a karaoke player/recorder that works with several audio and video formats.
But now I need to implement these new features:
1. Option to change in real time the "pitch" of MP4 files. (At the moment the pitch editor works only with audio files)
2. Record voice over MP4 file. (At the moment the voice recording works only with audio files)
