I'm in search of a program, that can convert/decompress 48.000 khz sound&wave files to 44.100 khz

Any ideas??

if this is for a live gig, be sure to resample the gig as a whole (if necessary join the audio-files). because if you resample track by track you will get bad track transitions

Might as well make sure he's splitting tracks properly while you're at it.

A fast and high quality sampling rate converter SSRC
written by Naoki Shibata


Homepage : http://shibatch.sourceforge.net/

This program converts sampling rate of PCM wav file. Also, this program has a function to apply dither to its output and extend perceived dynamic range.
Sampling rates of 44.1kHz and 48kHz are populary used, but ratio of these two frequency is 147:160, and it's not a small numbers. Therefore, samplingrate conversion without degradation of sound quality requires filter with very
large order, and it's difficult to achive both quality and speed. This programachived relatively fast and high quality with two different kinds of filters combined skillfully.




------------------

A question. Is dithering worth applying in these conversions?

Nah... it's not for a live gig. I think Dead knows, what it's for, but I've been bugging him enough, so I thought I'd ask around here
Anyway, I have solved the problem otherwise, but thanks, guys
