* Shows how to explicitly specify output file signal and encoding attributes.
*
* The example converts a given input file of any type to mono mu-law at 8kHz
* sampling-rate (providing that this is supported by the given output file
* type).
*
* For example:
*
* sox -r 16k -n input.wav synth 8 sin 0:8k sin 8k:0 gain -1
* ./example6 input.wav output.wav
* soxi input.wav output.wav
*
* gives:
*
* Input File : 'input.wav'
* Channels : 2
* Sample Rate : 16000
* Precision : 32-bit
* Duration : 00:00:08.00 = 128000 samples ~ 600 CDDA sectors
* File Size : 1.02M
* Bit Rate : 1.02M
* Sample Encoding: 32-bit Signed Integer PCM
*
* Input File : 'output.wav'
* Channels : 1
* Sample Rate : 8000
* Precision : 14-bit
* Duration : 00:00:08.00 = 64000 samples ~ 600 CDDA sectors
* File Size : 64.1k
* Bit Rate : 64.1k
* Sample Encoding: 8-bit u-law
