AW: AW: Incomplete format description?
...ption, the coding method has to be 0. > >I've been using libFLAC 1.0.4 to encode the stream. I've checked my interpretation against "flac -a" and it seems to read 17 bits for each warmup sample. Here is its output: frame=168 blocksize=4608 sample_rate=44100 channels=2 channel_assignment=RIGHT_SIDE subframe=0 wasted_bits=0 type=LPC order=5 partition_order=4 qlp_coeff_precision=12 quantization_level=9 warmup[0]=-993 warmup[1]=-476 warmup[2]=171 warmup[3]=115 warmup[4]=-766 Tor =================================================================== EASY and FR...

Getting subframe type=verbatim on 16 bit files
...I think that I'm using the calls in the typical order (see code below). But every monoe or stereo file that I send thru I get files that are the same sze as the orginal wave files. Doing a flac -a on the flac files I see that I get: frame=9 blocksize=4608 sample_rate=8000 channels=1 channel_assignment=INDEPENDENT subframe=0 wasted_bits=0 type=VERBATIM ....... Any idea why/ where I have goofed? Thanks, James Code snippet: =================================================== FlacEncoder flacCompressor; bool setValue = false; // set up regular...

rice format
...: -2, and with the Fixed predictor, I got the decoded sample: 2*1-1 +(-2) = -1, but the real number is 3.I can not figure out what is the problem. Is it the problem of the rice format? or the predictor? thanks this is what i got by: flac -a frame=0 blocksize=16 sample_rate=22050 channels=1 channel_assignment=INDEPENDENT subframe=0 wasted_bits=0 type=FIXED order=2 partition_order=2 warmup[0]=1 warmup[1]=1 -------------- next part -------------- An HTML attachment was scrubbed...
