I would appreciate advice on the best way to reduce the size of .wav files for archiving using lossless compression.
eg, is AIFF better than FLAC?
I have read this question: A compression tip, and SNR of version1.1 vs. 1.2?
but there is no answer to it.
My units are 1.00 and 1.1.0
The easiest way is just to zip the folders containing the WAV files. We typically only see about a 2/3 compression ratio which is probably typical what is possible. We did some experiments with simple on-board compression algorithms in the past and acheived something close to this on the device as well.
