Clear-Com has many products that can support AES-67, and this note only applies to the E-Dante card.
When receiving L24 encoded streams over AES67, it is possible for some channels to exhibit digital noise and to have a flatter waveform than expected.
Via Dante card (note the jagged high-end peaks):
Via LAWO R3LAY VSC:
The resolution is to set the E-Dante card’s preferred Sample Rate to match the incoming audio. Find the encoding setting from the SDP, 24 bit in this case:
o=- 53333 0 IN IP4 192.168.9.9
m=audio 5004 RTP/AVP 96
i=RAVENNA Audio-strm0/40,RAVENNA Audio-strm0/41,RAVENNA Audio-strm0/42,RAVENNA Audio-strm0/43,RAVENNA Audio-strm0/44,RAVENNA Audio-strm0/45,RAVENNA Audio-strm0/46,RAVENNA Audio-strm0/47
c=IN IP4 220.127.116.11/32
Then in Dante Controller or Domain Manager, set up the Preferred Encoding card-wide to match PCM 24:
