[MP3 ENCODER] Bug with -q1 (win32)

2000-05-23 Thread Ross Levis
I'm using new Win32 compiles from Dmitry. There appears to be a bug in LAME 3.84 CVS where it won't start encoding some WAV files (LAME -q1 file.wav). It just sits there doing nothing probably in an infinite loop. -q2 works fine. I managed to encode an entire album but for another album there

[MP3 ENCODER] Looking for educated guess or explanation

Hello, After a few dozen of those frequency analysis graphs, I noticed something that made me curious: The 16+kHz region of a VBR encoded file vs the 256S cbr. http://users.belgacom.net/gc247244/extra/why_oh_why.png [8KB] is a _very_ striking illustration, and I started thinking about this.

Okay, I isolated a 3 second clip from that track: http://home.hiwaay.net/~stephena/near-silence.wav http://home.hiwaay.net/~stephena/near-silence.mp3 I was wrong, earlier lame's encode the same way as the newer alphas. I am still surprised however at the bitrate selected for this piece. VBR

[MP3 ENCODER] Lame: Use for 320 JS frames in vbr mode?

2000-05-23 Thread Roel VdB
Hello, Is there use for 320kbit/s frames in JS mode? Lame -V1 -mj -h -b128 gives them regulary, and I remember someone told me that the max for each channel is 160kbit/s anyways, so there would be no quality improvement? or - are the saved bits used for bit reservoir? - to avoid switching too

[MP3 ENCODER] Fixed silly mp3input bug with libsndfile...

2000-05-23 Thread Sigbjørn Skjæret
Right, just committed a fix for a silly little bug which prevented mp3input to work together with libsndfile... I also noted that the --decode feature doesn't care about endianess, thus ending up with a big endian wav (read; garbage. ;) ) on big endian machines. Couldn't think up a quick fix
