Quick question with.. hopefully not that long of an answer.

I'm trying to play a sound file, store the FFT samples from the file somehow (most likely in text format), and then I want to be able to play back any individual FFT sample (looping it I guess).

Would anyone be able to explain how to do this to an absolute beginner? The more details the better!

Thanks to you all for trying to help me :)

Basically, you want to make a phase vocoder.

In the Max Examples, fft-fun section, you'll find a phase-vocoder-sampler patch. Open it, and you'll see in the patch the indication you are looking for: "Scrub through FFT analysis data". In this example, the FFT data is stored not in text format, but as float numbers, in a stereo [buffer~].

Thanks a lot for the response. That's very helpful, but I would still like to know if storing it in a text format is possible. Do you know?

That, or playing back through the samples in random order, which is the end goal I have anyway.

Sure. You can pretty much take anything in Max and store it in a text format. Just use the [text] object. To convert samples in a [buffer~] to text, you could [peek~] them into a [text], then write the text file to disk.

Thanks a lot! I will give that a try. I'm pretty new to max, but hopefully I won't find that too difficult! lol
