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

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

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

is it 8 bits-per-sample? if so, then the problem is this:
