Value Description
MP3 MP3 provides a common audio format for audio storage.
Supported values are 22 kHz, 44 kHz and 48 kHz. Most digital signals (HDMI
or SDI sources) use 48 kHz audio. Matching the encoded level with the source
level provides the best sound quality by avoiding audio resampling. For analog
signals, 44 kHz provides higher sampling.
Flash (FLV) doesn't support 48 kHz MP3 audio. When selecting this
value you'll need to use a media player (or install ASF browser
plugins) to preview your channel.
PCM Pulse Code Modulation (PCM) is a standard for digital audio in computer and
other devices such as, digital telephone systems.
Most digital signals (HDMI or SDI sources) use 48 kHz audio. Matching the
encoded level with the source level provides the best sound quality by avoiding
audio resampling. For analog signals, 44 kHz provides higher sampling.
Flash (FLV) doesn't support 48 kHz PCM audio. When selecting this
value you'll need to use a media player (or install ASF browser
plugins) to preview your channel.
AAC AAC is the default audio codec.
This codec is comparable with MP3, and may have better sound quality with a
similar bit rate. Supported values are 16, 22, 44 and 48K kHz. Most digital
signals (HDMI or SDI sources) use 48 kHz audio.
Matching the encoded level with the source level provides the best sound
quality by avoiding audio resampling. For analog signals, 44 kHz provides
higher sampling.
The maximum bitrate for mono encoding of a 44 kHz signal is 264 kbps. For
stereo, 320 kbps is supported.
G.711 8KHz (a-Law) Used primarily in North America for streaming and recording voice. This codec
uses only 64 kbps of bandwidth.
G.711 8KHz (µ-Law) Used in counties outside North America.
