I would like to read a sound file and determine the frequency of each note. What do I need with Lazarus 2.0.2 in Windows 10?
Hello.
With
uos (
https://github.com/fredvs/uos), you may get the spectrum frequency of mp3, ogg, wav, flac, m4a, opus, cda sound files.
In
StrumPract project (
https://github.com/fredvs/strumpract), there is the Pascal/fpc code to do the spectrogram using
uos.
[EDIT] If you are talking about note recognition from a piece of music (writing the partition), like voice recognition does from a discussion (writing it to text), huh, at the moment I did not find anything working.
I get some result for monophonic music but once there are chords it does not work ok.
