Detailed Description

Converts 8, 16, 24 and 32 bit samples in any combination.

Todo:

Optimize for speed.

This class offers only one static function that is able to convert a buffer of 8, 16, 24 or 32 bit samples to a buffer of 8, 16, 24 or 32 bit samples.

Member Function Documentation

void ac3::CBitResConverter::ConvertBitResolution (  UINT32    nSampleCount, void *    pSource, UINT16    nSourceResolution, void *    pDest, UINT16    nDestResolution )  [static]

Converts 8, 16, 24 and 32 bit samples in any combination. Parameters: nSampleCount  Number of samples in pSource buffer. pSource  Buffer containing source samples. nSourceResolution  Resolution of samples in source buffer (8, 16, 24 or 32) pDest  Buffer to store the converted samples to. nDestResolution  Resolution to convert to. Converts nSampleCount samples from pSource with nSourceResolution to pDest with nDestResolution. Allowed values for nSourceResolution and nDestResolution are 8, 16, 24 and 32 in any combination. If nDestResolution is equal or higher nSourceResolution the conversion is not lossy. Note that 8 bit data is unsigned and a "silent" sample (-inf db) has value 0x80. 16, 24 and 32 bit data is signed and a "silent" sample has value 0.
