If you care about sound quality, you should always use a dithering algorithm when truncating. Its trivial as well, just add an eight bit random number to the 24 bit value, and then shift right. There are better algorithms, but in an embedded system, adding is nearly as trivial as shifting. Again, I don't know what Sox is doing. Proper conversion from 96 to 44.1 is more complex, but there is a chance that the Classic/SB3 can process 48kHz natively. So there is no need to bother going to 44.1 Obviously if you are doing FFTs to try to use digital transformation, then you will use a ton of CPU power -- Pat Farrell http://www.pfarrell.com/ _______________________________________________ discuss mailing list discuss@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/discuss
