Near-lossless / lossy FLAC Reply #25 – 2007-06-13 18:59:41 SebG,Ah, I see. Well, it might be interesting to try. It sounds like you're tempted to do it! Josh PM'd me to point out that the FLAC frame/block size can be set from the command line using the -b command. I've just tried it, and it works as expected: with the MATLAB code changed to use 1024 sample blocks, it seems I get better compression, but I need to try more samples. On the one I tried (41_30sec) this shaved another 20% off, though that sample encodes 3% more efficiently in 1024 sample blocks than 4096 blocks anyway.Cheers,David.
