What is the format of the files? Raw audio, WAV, etc? What is the rough content - if the signal is constant than sample insertion is not easy since you may not have periods of silence. If the signal does have silent periods then the solution may be a noise gate that inserts samples - this would be all but inaudible. There is no reason why this should not work from file to file with 'cat oldfile | <program> > newfile so should not need to have the lot in memory.
Sounds cool. It also sounds simple enough for me to put together on my own. The files are in mono wav. I could pipe them through sox to get them to raw if that's easier to manipulate. But I think I need to read up a bit on audio formats. I need to know how many bytes to read to get one sample, given a specific sample rate. And if I convert them to raw I need to find out how to get them back to wav with the right header attached. What are the best places to read up on that? alex -- Alex Polite http://flosspick.org - finding the right open source
