In Members

format: Contains the format constant - MSS supported values are WAVE_FORMAT_PCM for standard, uncompressed wave files and WAVE_FORMAT_IMA_ADPCM for IMA ADPCM compressed wave files.
data_ptr: Contains a pointer to the beginning of the sound data in the wave file.
data_len: Contains the length of the sound data in the wave file.
rate: Contains the playback rate of the wave file.
bits: Contains the bit depth of the sound data (usually 4, 8, or 16).
channels: Contains the number of channels in the wave file (1 is mono, 2 is stereo).
channel_mask: Specifies the Microsoft WDM-compatible 32-bit channel mask for multichannel samples, or ~0U for traditional mono or stereo samples. See the How do I use multi-channel sound output in Miles? FAQ for more information on channel masks and multichannel content authoring.
samples: Contains the total number of samples in the wave file (used with ADPCM).
block_size: Contains the IMA ADPCM block size.
