WavePlayer-2 Commands
OTHER SIMULATION TOOLS
The WavePlayer-2 is a Huron application that can play .WAV
format audio files. WavePlayer-2 does not use any Huron DSP
resources, and it is not constrained to the 2Mb memory limit of
the original WavePlayer application.
The SNAPWP2LoadWave function blocks and returns only
after the load has succeeded or failed. The return code reflects
whether WavePlayer-2 was able to successfully load the wave
file. All other WavePlayer-2 functions are non-blocking.
Their return codes indicate whether each command was
successfully sent to the Huron.
Valid wave IDs are 1 to 256 inclusive. Valid voice IDs are 1 to
128 inclusive.
The sample code shown below provides an example of how to
control WavePlayer-2 using the SNAP API.
if (SNAPConnect("127.0.0.1"))
{
/* Load sample.wav as wave 1 */
if (!SNAPWP2LoadWave(1, "C:\\wavs\\sample.wav"))
printf("Could not load wave file.\n");
else
{
/* Bind voice 5 to wave 1, outputting on channels 3 and 4 */
long lChans[2] = {3, 4};
SNAPWP2BindVoice(1, 5, 2, lChans);
}
/* Start voice 5 playing */
SNAPWP2PlayVoice(5);
/* Wait for voice to finish playing */
...
/* Release the voice */
SNAPWP2ReleaseVoice(5);
/* Remove the wave */
SNAPWP2RemoveWave(1);
}
SNAPDisconnect();
