Supported audio codecs and bitrate guidance
Value
Description
AAC
AAC is comparable to MP3 and may even provide better sound quality at a similar
sample bitrate. Supported sampling bitrate values are: 16, 22, 44 and 48K kHz.
Setting the channel bitrate to match the audio source's bitrate provides the best
sound quality and avoids audio resampling. Most digital signals (HDMI
or SDI sources) use 48 kHz. Most digital signals (HDMI or SDI sources) use 48 kHz
audio. For analog signals, 44 kHz provides a good quality audio sample.
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
