Custom sample rate for recording?

[Guest]

Is there a way to enter a custom sampling rate (i.e., not from the pull-down list available in CS6)? For example, can I set the sampling rate to be a particular value (e.g., 15.625 KHz or even 7.8125 KHz).

The reason is I don't want to down-sample and up-sample the WAV files. I want to reduce conversions and transcoders as much as possible in the recording path to match the audio signature with what is being sent between hardware devices I'm working with.

Yes you can manually type in a required sample rate, rather than selecting from the normal drop down list, when you go to File/New/Audio File. However I am rather intrigued as to what devices you have that require these strange non standard audio sample rates? But Audition has one of the best sample rate conversion algorithms around which shouldn't compromise your audio quality, especially if you start by recording at a higher standard rate.

Whilst you can certainly do this in Audition, you may find that you are somewhat more limited with your sound device, as most of them are optimised to work at standard rates, and are unlikely to tolerate being asked to run at non-standard speeds. But as ryclark says, Audition's resampling has been measured independently as being pretty much the best there is. So what are these sound devices? I'm also intrigued...

Thanks. It isn't immediately obvious that one can simply type in what sampling rate they want; it looks as if the pull-down options are the only selections available.

This sample rate has to do with speech recognition in a particular environment.

No it wasn't obvious to me either as normally most people just use one of the standard listed sample rates. However knowing Audition from experience the Sample Rate box looked as if it could be typed into. So a little trial, and no error, proved that it could.
