These programs are designed to access an AMBE3000 vocoder connected to a serial port or a USB port and to allow for the encoding and decoding of WAV files to and from different AMBE formats.

There are two programs, AMBE2WAV and WAV2AMBE and their purposes are obvious from their names. The usage of them is:

ambe2wav [-v] [-a amplitude] [-g ] [-m dstar|dmr|ysf|p25] [-f 0|1] [-p ] [-s ] [-r] [-d]

wav2ambe [-v] [-a amplitude] [-g ] [-m dstar|dmr|ysf|p25] [-f 0|1] [-p ] [-s ] [-r] [-d]

where

[-v] print the version and exit.

[-a amplitude] is the gain applied to the WAV file data, the default is 1.0

[-g signature] is an optional prefix at the beginning of the AMBE file

[-m dstar|dmr|ysf|p25] is the mode for which the AMBE will be generated. Note that P25 requires special hardware.

[-f 0|1] is whether FEC should be applied.

[-p ] is the serial port where the AMBE chip is attached, default is /dev/ttyUSB0

[-s ] is the speed of the AMBE chip interface, default is 460800 baud

[-r] issue a reset at startup

[-d] print debugging information
