[MP3 ENCODER] Some observations of vbrtest problem

2000-07-16 Thread Naoki Shibata
I think it is certain that this problem is caused by noises concentrated on pure tones. A noise on a single MDCT coefficient increases as it's amplitude increases. This is because quantized values are actually values powered by 3/4. According to the theory of psychoacoustic, it is a wonder why

[MP3 ENCODER] MP3 decoder comparison

2000-07-16 Thread Alberto García
In http://privatewww.essex.ac.uk/~djmrob/mp3decoders/index.html there's a comparison of mp3 decoders. Lame is one of the three that passed the test (the other two are Winamp 2.22 and Ultra Player). But mpg123 is not tested. What about it? Does anyone know any decoding problem with it?

Hi Chris! Christopher Wise schrieb am Mon, 17 Jul 2000: I want to encode a number of wave files into a single mp3 file. Since lame doesn't appear to be able to do this, the obvious solution woudl be to concatenate the wave files first. Are there any utilites under linux or windows
