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

  -v  Show version info

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 754.5 and 1509.75 AT _48kHz_ are an exception.
