[Gnump3d-devel] Downsample suggestion

[Aaron Longson]

     Whenever I upgrade gnump3d, I change the medium downsample command
from:

downsample_medium_mp3 = /usr/bin/lame  --mp3input -b 32 $FILENAME -

to:

downsample_medium_mp3 = /usr/bin/lame  --mp3input -m m -b 32 --resample
22.05 $FILENAME -

    This resamples the file to 22.05Khz(from the usual 44Khz or 48Khz)
and converts it from stereo to mono.
    Before the change, some songs suffered from extremely poor quality.
 I figured the drop in sampling rate and loss of stereo are a worthy
exchange for good listening quality on all songs.  At 32kbps, its a
game of losses anyway.

    In the past, I had a patch to convert mp3 to ogg, so I could send
at a lower bitrate with better quality.  I've since stopped maintaining
it because the above command provides an acceptable compromise with
better compatibility with various players, and doing the ogg conversion
elegantly in step with the rest of the code became more difficult. 
Someone who knows the flow of the program might have an easier time of
it.  I think my ogg stream was down to 12kbps for equivalent quality,
well under my employer's radar.

    Sorry if this has been mentioned before, I didn't check the Archives.
