[HELP] Change audio frequency #408

Closed FilipeOS closed 3 years ago

FilipeOS commented 4 years ago

Hi there,

Basically I'm trying to listen/play at same time to frequency between 2.35Hz and 2.5Hz.

How it would be possible to archive this?

I learned mainly Java but I'm trying to do both platforms that's why I'm using Flutter. Thank you!

Does someone can answer to @FilipeOS ? This is too technical for me 👎

+1: I am trying to achieve someting similar, but I don't know how to reach that. All the libraries for sound on flutter are about save audio to file and play audio from file, I think I'd need sometime on-the-fly, some open stream giving back constantly the byte arrays (maybe?), in order to be able to apply some manipulation (fft, maybe again)..

I just found something at least near to my problem: https://github.com/dooboolab/flutter_sound/issues/90 I'd say that the only thing is to access to the audio data itself while passing from the recorder to the player, in order to apply some filtering in the middle

I am not to understand fully your needs, but you could look to this notice

Please re-open this issue if you have still problems. Actually I do not really understand your needs. Probably it duplicates [#479]
