Audio encoders
There are 3 audio encoders: one G.7xx encoder, one AAC encoder and one Linear PCM encoder.
Up to 3 encoders can be used providing that they are requiring the same sampling rate. This is
tested and enforced by the web service layer, that will not allow simultaneous use of two
encoders requiring conflicting sampling rates.
WARNING: important side-effect: producing G.711 out of de-embedded audio might thus be
available only when embedded audio is sampled by the source at 8kHz.
Audio outputs set
The audio stream can feed:
n
Two digital audio channels of the HDMI Output
n
Left and Right channels of the analog audio output through a stereo DAC converter.
Note: HDMI audio output is not available in firmware version 1.0
