Low-Delay Audio
Low-Delay Audio
Low-delay audio is an encoding mode that produces compressed audio with a smaller buffer-window setting than other modes. This is useful for streams that need to be switched quickly during playback. The typical scenario for this feature is a streamed presentation that includes the ability to arbitrarily switch content, like changing the channel of a television.
When you use a low-delay audio format, the latency for switching content is drastically reduced compared to other audio formats. Latency is also reduced for live broadcasts when you use low-delay formats.
This feature is supported by the Windows Media Audio 9.1 and Windows Media Audio 9.1 Professional codecs. Low-delay formats are available only for constant bit rate encoding (both one-pass and two-pass).
