I'd like to know your point of view on the "Free format" that lame generates.
I've created a free format file with 'lame --freeformat -b 62 file.au". I'm using lame
3.86beta on Win32 compiled locally using MinGW32 with Libsndfile and full speed
optimization (all I found usefull in the GCC doc). And it usually works fine.
But with free format, it sometimes generate half frames. The file seems to have the
following characteristics :
MPEG_VERSION MPEG_2
MPEG_LAYER LAYER_III
PROT_BIT 0
BIT_RATE 1
SAMPLE_FREQ 22050
SAMPLES_PER_FRAME 1152
PAD_BIT 0
PRIV_BIT 0
CHANNEL JOINT_STEREO
MODE_EXTENSION Intensity OFF / MS ON
ID3V2 0
FRAME_LENGTH 405
COPYRIGHT 0
ORIGINAL 1
EMPHASIS NONE
CHECK_STATE 1
BIN_STRING 11111111111100110000000001100100
BIT_RATE = 1 means free format.
I've checked the file in hexadecimal, and sometimes I get frame header at 202 bytes
from the previous instead of 405. So I was wondering if this is not a bug of lame or
if the free format allow this (but I don't think so).
The other possibility is that the real frame size is 202 bytes, but then would some of
the frames would be separated by 405 bytes ?
any opinions welcomed (I can make the files available if necessary)
thx
