Re: Pixelgrabber equivalent for Music(MIDI/MP3)

MP3 files are fancy compressed frequency domain representation of the audio time domain waveform (periodic amplitude measurements of the sound waves). The good thing is that because it is based in the frequency domain it would possible to get approximate 'notes' without too much processing.. although that would still be a complex task.

I don't know enough about MIDI, but I was under the impression that it stored 'note' information in a much more direct manner.

But the two formats are completely different in almost every possible way... so if your program intends to perform the same analysis on either format you will likely need some sort of intermediate representation to convert to. The conversion could be more difficult than your core analysis.

You can google for specifications and existing decoders for both formats.

Greg,
If I cannot retrieve a note value from a MIDI/MP3 file, what values can I get? I am trying to do music/audio analysis of MIDI/MP3 files.
Thanks again.
