AvgBytesPerSec Property

The AvgBytesPerSec property gets and sets the required average data-transfer rate for the format tag in bytes per second.

If the FormatTag property is WAVE_FORMAT_PCM, AvgBytesPerSec should be equal to the product of SamplesPerSec and BlockAlign. For non-PCM formats, this member must be computed according to the manufacturer's specification of the format tag.

Playback and record software can estimate buffer sizes using the AvgBytesPerSec member.
