Hello
We do have the problem to encode a ripped .wav file into a .mp3 file.
Ok, seems to be no problem, but we just want a 30sec piece of the
audiofile
and this after the first minute. (encode 1:01 to 1:31)
A solution would be a wave-editor, but it should be running in a batch,
no interactive program. I grabed the lame source, open main.c and :
int makeframe(void)
{
int iread;
static short int Buffer[2][1152];
iread=lame_readframe(Buffer);
/* even if iread=0, get_audio hit EOF and returned Buffer=all 0's.
call
* makeframe() one last time to flush all buffers */
lame_encode(Buffer,mp3buffer);
return iread;
}
So, its seems to be that easy, just count a few lame_readframe
without invoking lame_encode, ...
Ok, searched a bit and what is done is reading PCM-frames.
They use 2x1152 bytes,
BUT: how long is a PCM-Frame in seconds?
Answers are welcome, and thanx in advance
