Configure audio encoding
Value
Description
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. Note that lower bitrates (e.g. 32 kbps) with a 44
kHz signal may result in distorted audio.
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 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.
Flash (FLV) doesn't support 48 kHz PCM audio. When selecting this
value you'll need to use a media player to preview your channel.
