Subsections
Many of the following features override the encoder's
idea of best-quality settings. You should be aware that overriding the encoder
default settings is something for experts. You might wreck the encoding quality
in a number of ways without first noticing it. Also, the encoder is not guaranteed
to run at all parameter combinations. Proceed at your own risk!
- -k
- Tell the encoder to use full bandwidth. By default,
the encoder uses a 16kHz bandwidth up to 64kbps per channel, and full bandwidth
at higher bitrates Increasing the bandwidth from the default setting might
produces ringing artefacts at low bitrates. Use with care!
- -e
- For transmission over serial lines with bit errors, parts of the bitstream
can be protected by calculating a CRC checksum. If you are just producing
for harddisk storage, there is no need to set this switch. This feature is
not yet working.
- -a
- This switch tells the encoder to autoconvert a stereo input signal into
one channel, producing mono output. The downmix is calculated as the sum of
the left and right channel, attenuated by 6 dB.
- -f
- This switch forces the encoder to use the
"extra fast" encoding mode. It will reduce the quality
of the output. This might be useful for real-time processing on slowest computers.
