Echo cancellation does not fully work, even after the basic fixes
AEC is not magic, it needs a reference signal and a reasonable acoustic environment. Too much reverb, too close to the speaker or wrong routing and cancellation fails.
Try this first
- 1Check that the room system receives the speaker output as reference, in a DSP setup you must route this explicitly.
- 2Lower speaker volume to 65 to 75 dB at listening position, loud speakers create more than AEC can absorb.
- 3Do not place an external speaker at or in line with the mic, a speaker directly under a ceiling array invites trouble.
- 4A DIY DSP needs a short room tune, most DSPs like Shure IntelliMix, Q-Sys, Biamp do a room measurement at install.
- 5Test with a dynamic conversation not isolated phrases, AEC needs longer references to learn.
- 6Update mic and DSP firmware, AEC algorithms improve with updates.
When to bring us in
If it keeps stuttering, an acoustic fix or on-site DSP tuning is needed. Vectel can do that on location.
