The audio quality of content that is compressed using this codec is the best of all Windows Media Audio codecs. It creates a bit-for-bit duplicate of the original audio file so that no data is lost, which makes it ideal for archiving content masters. Depending on the complexity of the original, content will be compressed at a or ratio. Although this is lower than the ratio achieved with other Windows Media Audio 9 Series codecs, it provides the same benefits of compression while leaving the data intact.
Like Windows Media Audio 9 Professional, the 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.
Using the Quiet Mode feature in Windows Media Player 9 and later, users can hear the full dynamic range, a medium difference range up to 12 dB above the average, or a little difference range up to 6 dB above the average. This low-bit-rate codec is primarily targeted for speech content, but performs very well with mixed-mode content that includes both voice and music.
In voice mode, the codec takes advantage of the relatively less complicated and narrower frequency range of the human voice to maximize compression. In music mode, the codec operates like the standard Windows Media Audio 9 codec. Encoded content can be configured to switch between voice and music modes automatically. The Windows Media Audio 9 Voice codec offers superior quality for low-bit-rate streaming scenarios less than 20 Kbps , such as radio broadcasts, advertising, e-books, podcasts, and voiceovers.
The voice codec can also compress content to as low as 4 Kbps at 8 kHz. The following table outlines what your audience will experience when playing Windows Media Audio 9 Series content on earlier Microsoft Windows operating systems than Windows XP or with earlier versions of Windows Media Player. Formal standardization of VC-1 represents the culmination of years of technical scrutiny by over 75 companies, leading to a codec that is well-documented, extremely stable, easily licensable, and accepted by the industry.
VC-1 supports three profiles: Simple, Main, and Advanced. Was this information helpful? Yes No. Thank you! Any more feedback? The more you tell us the more we can help. Can you help us improve? Resolved my issue. Clear instructions. Easy to follow.
