Audio from the WAV file is transmitted on all frequencies. However if the "-A" option is given, program content for the second DMR time slot is instead taken live from the sound card audio input port ("-I" option). <h3>GENERAL</h3> Input audio may come either from WAV files (8000/S16_LE/mono) or from the PC microphone / line input connector. If <code>-f <em>filename</em></code> (or <code>-F <em>filename</em></code> in DMR mode) is selected the input is read from file(s); otherwise the GR audio source is selected. Likewise output is sent to the soundcard unless <code>-o</code> is given. When using files the <code>-r</code> option can be specified to replay the input file(s) in a continuous loop. Without this option the program exits at EOF. The <code>-p <em>protocol</em></code> option is used to select which of the four DV standards (dmr, dstar, p25 or ysf) is to be used. The dmr and ysf modes also utilize a configuration file, specified using the <code>-c <em>filename</em></code> parameter. See the specific section (below) for more details on the configuration file. <p> |
