WavePlayer Commands Parameter Description OTHER SIMULATION TOOLS The WavePlayer is a Huron application that can play 24 bit audio data in .Sim file format only. Data is played out of Huron DSP memory. Multiple voices can be played at varying pitches and amplitudes. It can load a large number of different audio waves and play any wave on any voice. Up to 2 Mb of audio data can be loaded into the WavePlayer. When wave data is downloaded to the Huron from the remote computer a wave name and checksum must be passed in the SNAPSetWaveHeader command, followed by the data in the SNAPSetWaveSamples command. When SNAPSaveTransferWave is issued the data is saved onto the Server (Huron’s) hard disk drive and downloaded into the WavePlayer. The SNAPLoadWave command requires that a wave name and a checksum is sent. The Huron checks these parameters against the waves stored on its hard disk drive, and will load the wave directly from its own disk, if it can. The WavePlayer plays voices. To attach a wave to a voice use the SNAPUpdateVoice command, and then use SNAPTriggerVoice and SNAPReleaseVoice to play and stop the voice playing. While the voice is playing it is possible to send further SNAPUpdateVoice commands to change the pitch and the level of the voice. SNAPGetWaveProp This command is received by the WavePlayer application which sends a SNAPGetWaveProp packet back to the remote computer with the variables of the SNAPGetWaveProp structure filled in as follows. The WavePlayer application must be running in the VRack for this command to return. out long* plVersion Version of WavePlayer TCP/IP Interface out long* plFlag Currently unused out long* plVoices Number of voices currently selected in the WavePlayer out long* plWaves Maximum number of waves that can be loaded out long* plTotalSamples Maximum number of 16 bit samples that Huron can store out long* plFreeSamples Number of free samples not used for storage HURON TECHNICAL MANUAL PAGE 174
OTHER SIMULATION TOOLS SNAPSetWaveHeader When downloading fresh wave data to the Huron from the remote computer this command must be sent prior to the sending the data for the wave. in long lWaveID The waveID that you want to assign to this wave. If the waveID is already taken by another wave, that wave has the ID removed from it. A single wave can be assigned multiple waveIDs. It is removed from the WavePlayer’s memory when its last ID is removed. in long lFrames Number of frames in the waveform. A frame contains a sample for each channel. in long lSRate Sample rate of the wave. in long lLoopType Currently ignored. If loopStart is less than loopEnd then the wave will loop forward, otherwise the wave will only play once when triggered in long lLoopStart Start sample of loop in long lLoopEnd End sample of loop in const char* szWaveName Name of the wave in long lChecksum Checksum SNAPSetWaveSamples Once the header has been sent the data can be sent using the SNAPSetWaveSamples command. in long lWaveID The waveID that you sent in the SNAPSetWaveHeader command in long lChannel Channel number. As only mono waves are supported this field is ignored. in long lOffset Offset in samples from the start of the waveform that this data is for. in long lLength Number of samples that is being set. in short* psSamples The data. Only HURONTCP_MAX_SAMPLES (defined in HuronTCP.h) may be transferred with one command. If your wave is bigger then you must split the wave into chunks and send it piece by piece. SNAPSaveTransferWave Once all the data has been sent to Huron the SNAPSaveTransferWave command must be sent. This command will cause the data to be saved to Huron’s disk and transferred to the WavePlayer’s memory. in long lWaveID The waveID that you sent in the SNAPSetWaveHeader command SNAPLoadWave If the wave required is already stored locally on the Huron, this command may be sent. The Huron will attempt to find the wave at the specified path. The Huron stores wave data in SIM files. See the SIM Tools section in this manual for an explanation of the SIM file format. If the load message is not received, a -1 is returned in the data field. HURON TECHNICAL MANUAL PAGE 175
