Hi all! Apologies for the slightly vague subject line.
Basically, as part of forensics coursework I have created an audio stream of an image using Coagula.
I then mixed this with audacity to produce a secondary , combined audio stream having changed the rate of the image stream so when they are listened to together the image is not perceptible. ( Hope this is making sense!)
So, I now have the original audio stream which is a song. And the modified stream of the image ‘noise’ and the song.
I’m looking for a way to provide both stream to Audacity and subtract the original stream from modified leaving the image noise.
So, (Modified Stream - Original Song) = Image Noise which I can then run through something like Sonic Visualiser to see the image again.
Is this possible in Audacity at all?
