Minim: manipulating a float buffer
Feb 13^th, 2009, 10:55pm

So, I want to open a sound file, manipulate the buffer in non-realtime and save it as a new file using Minim. Like in a simple sound editor.

AudioPlayer has three AudioBuffer fields (inherrited from AudioSource); left, mix and right.
AudioSource has methods for getting the samples as float values, but as far I can see it is not possible to set them or to create a new AudioSource from a float array /multiple float arrays.

Is there any way of manipulating a float buffer in Minim?

I'd need to manipulate audiofloats, too.
not in realtime and just for the output.
Tell me once you found something, I'll do the same!
edit: maybe there is a simple a simple file type we could read and write with getbits?

in detail: I need to combine one sample with a random offset into a loop-like samples I can merge to the following: Something like an endless echo I can feed with the sample until I have noise only and even further.
Needs to be quite accurate and merged to a single array because there will be thousands of repetitions of the sample and I need to control the volume in very small steps (1/6000 volume e.g.).

It kind of works, but it is way too messy to share.
