Basic command line switch reference
Only the most usual switches are described here. However those should be sufficient
for the vast majority of users.
switch
parameter
#-abr
--abr
average bitrate encoding
#b
-b
bitrate (8...320)
#-decode
--decode
decoding only
#f
-f
fast mode
#h
-h
high quality
#-help

#m
-m m

#V
-V
VBR quality setting (0...9)
*
--abr n
average
bitrate encoding
Turns on encoding with a targeted average bitrate of n kbits, allowing to
use frames of different sizes. The allowed range of n is 8-320, you can use
any integer value within that range.
*
-b n
bitrate
For MPEG1 (sampling frequencies of 32, 44.1 and 48 kHz)
n = 32,40,48,56,64,80,96,112,128,160,192,224,256,320
For MPEG2 (sampling frequencies of 16, 22.05 and 24 kHz)
n = 8,16,24,32,40,48,56,64,80,96,112,128,144,160
Default is 128 kbs for MPEG1 and 80 kbs for MPEG2.
*
--decode
decoding
only
Uses LAME for decoding to a wav file. The input file can be any input type
supported by encoding, including layer I,II,III (MP3).
*
-f
fast mode
This switch forces the encoder to use a faster encoding mode, but with
a lower quality.
*
-h
high quality
Use some quality improvements. Encoding will be slower, but the result
will be of higher quality.
This switch is always enabled when using VBR.
*
--help
help
Display a list of all available options.
*
-m m
mono
mode
The input will be encoded as a mono signal.
*
-V 0...9
VBR quality
setting
Enable VBR (Variable BitRate) and specifies the value of VBR quality.
default=4
0=highest quality.
