LAME Quality settings in Amadeus II

Post by ben »

I'm wondering what the Amadeus II LAME "Quality" settings correspond to exactly in terms of LAME commands. Is quality "Best" equivalent to -q 0 or -q 2 (-h)?

Also, the way I interpret it, when the VBR box is not checked, the VBR settings in the Expert tab don't apply (I assume that CBR is used instead). Is that true?

Thanks.

more on LAME commands

Post by ben »

While I'm at it, what are the actual LAME commands used? For example:

In Amadeus II, I converted a file from WAV to MP3 with the following settings:
  • Bit Rate: 24 kbps
    Quality: Best
    Resample: 22.05 kHz
    Variable bitrate: unchecked
    Force mono encoding: checked
Then in iTunes-LAME (the application by Blacktree) I converted the same WAV file to MP3 with the following arguments:
  • -m m --resample 22.05 -b 24 -q 0
When I compared the two output files, I detected a slight difference in the audio quality--the Amadeus MP3 was a little less distorted. So I'm wondering what those settings in Amadeus II would produce as far as LAME arguments. Does it automatically add something like a lowpass filter at low bit rates? Or could it be that iTunes-LAME's v3.97 LAME encoder produces a different output than Amadeus II's v3.96?

But I guess most importantly, my question is could you tell me the exact LAME arguments that Amadeus II uses in the above example.

Thanks.
