Title: LAME/MP3 Encoder VBR Sample Rate Problem
Post by: zurn on March 03, 2003, 06:18:02 am

I accidentally recorded some .wav files from a source with 48 Khz sample rate, then encoded using MP3 VBR with a custom setting:
--alt-preset fast standard

The resulting mp3's were a bit longer and slower.  I found the way using LAME at the command line to encode the wav's correctly:
-s 48 --alt-preset fast standard

But when i insert that same string into the Custom line in MJ8, it actually comes out shorter and faster sounding!

Seems like it's doing something different there.   Just wanted to ask if it's me or MJ doing something wrong!
;)

thanks, Steve

is there an -s 44

?

maybe you should use that.

There is, but my understanding from LAME help was that that flag specified the sample rate of the input file...which was 48, but i see what you're saying:  if it's fast on 48, maybe specifying 44.1 will correct it--but it still seems like there's a problem with the implementation of the "Custom" option.

I'll try it, though (which will probably be tonight).

thanks.

44 is kind of a standard for wave files.

there has always been a problem with the change in the Khz.

If there was an analog conversion i would think this would not be a problem.
