FFDCAENC --- experimental 'Coherent Acoustics' compressor.
Usage:
ffdcaenc -i <input.wav> -o <output.dts> -b <bitrate_kbps>
Optional:
-l Ignore input length, can be useful when reading from stdin
-e Switch output endianess to Little Endian (default is: Big-Endian)
-r Reduced Bit Depth for DTS CD format (default is: Full Bit-Depth)
-h Print this help screen
-c Overwrite the channel configuration (default is: auto-selection)
-f Add an additional LFE channel (default: used for 6-channel input)
-m Multiple Mono input files (default: -i for multi-channel input file)
Use -0 <input.wav> -1 <input.wav> etc. (up to -5) Channels are in ITU order:
0,1,2,3,4,5 --> LF, RF, C, LFE, LS, RS
The following mono input file combinations are supported:
1.0 -2 center.wav
1.1 -2 center.wav -3 lfe-wav
2.0 -0 left.wav -1 right.wav
2.1 -0 left.wav -1 right.wav -3 lfe.wav
3.0 -0 left.wav -1 right.wav -2 center.wav
3.1 -0 left.wav -1 right.wav -2 center.wav -3 lfe.wav
4.0 -0 left.wav -1 right.wav -4 ls.wav -5 rs.wav
4.1 -0 left.wav -1 right.wav -4 ls.wav -5 rs.wav -3 lfe.wav
5.0 -0 left.wav -1 right.wav -2 center.wav -4 ls.wav -5 rs.wav
5.1 -0 left.wav -1 right.wav -2 center.wav -4 ls.wav -5 rs.wav -3 lfe.wav

REMARKS:
The input or output filename can be "-" for stdin/stdout.
The bitrate is specified in kilobits per second and may be rounded up
-- use floating-point values for bitrates that are not a multiple of 1 kbps.
Because the encoder uses a 4-byte granularity, i.e., 32 bits per audio frame
(with 512 samples/frame), the ACTUAL bitrate will always be a multiple of:
3 kbps for 48 kHz
2.75625 kbps for 44.1 kHz
2 kbps for 32 kHz
1.5 kbps for 24 kHz
1.378125 kbps for 22.05 kHz
1 kbps for 16 kHz
0.75 kbps for 12 kHz
0.6890625 kbps for 11.025 kHz
0.5 kbps for 8 kHz
-- NOTICE: the values 377.25, 503.25, 754.5 and 1509.75 AT _48kHz_ are exceptions.
