}

Specifies the format of data in a sound buffer.

Fields

avgBytesPerSec

Required average data-transfer rate, in bytes per second, for the format tag.

bitsPerSample

Bits per sample for the formatTag format type. If a compression scheme cannot define a bits-per-sample value, this field is zero.

blockAlign

Block alignment, in bytes. The block alignment is the minimum atomic unit of data for the formatTag format type. Playback and record software must process a multiple of blockAlign bytes of data at a time. Data written and read from a device must always start at the beginning of a block. For example, it is illegal to start playback of PCM data in the middle of a sample (that is, on a non-block-aligned boundary).

channels

Number of channels in the waveform-audio data. Monaural data uses one channel and stereo data uses two channels.

extra

Array variable that contains extra format information.

formatTag

Waveform-audio format type. Format tags are registered with Microsoft Corporation for many compression algorithms.

samplesPerSec

Sample rate, in samples per second (hertz), that each channel should be played or recorded.

size

Size, in bytes, of extra format information.
