Re: [LAU] (Auto-)Tune a wave file

Hello, I have samples here, single-note recordings from instruments, that need tuning. I am looking for a permanent/destructive way to do that. I can do the batch processing part myself so I only need a hint how to do it for one file. The file(s) are nearly correctly tuned and I already know what it is supposed to be, if that helps. Example: I have a file resembling the midi a4 which should be 440hz, but maybe it is 430 to 450. So the optimal input would be: "Tune this file to a4" where the analysis of the actual frequency is done by a program. Quality is the top priority. Since the tuning is very fine I don't care if the speed of the recording changes or not. I take what sounds best. So, any command line tool available for that? If not a GUI tool is fine as well.
