Windows Media Audio Lossless (WMA Lossless) is a lossless audio codec from Microsoft that compresses audio signals without loss of quality from original using VBR. When decompressed, the audio signal is an exact replica of the original. Windows Media Audio 9 Lossless codec also offers dynamic range control using the maximum and average audio amplitudes that are calculated during the encoding process. WMA Lossless also supports down-mix when the capable audio hardware isn't present.
VINJEY has ported and optimized WMA Lossless codec on popular DSP platforms based on the implementation provided by Microsoft to its licensees. VINJEY's WMAL implementation is an interim product, hence using VINJEY's port requires license from Microsoft.
