To use the Optimize workflow:
Place all relevant devices in a location.
Select Optimize. Designer optimizes microphone and DSP settings for your equipment combination.
If you remove or add devices, select Optimize again.
IntelliMix DSP
This device contains IntelliMix digital signal processing blocks that can be applied to the automix channel output. The DSP
blocks include:
Acoustic echo cancellation (AEC)
Automatic gain control (AGC)
Noise reduction
Compressor
Delay
To access the DSP blocks, select the IntelliMix tab. When enabled, each DSP block will be colored.
Selecting Bypass IntelliMix will bypass the following DSP blocks: AEC, AGC, noise reduction, compressor, and delay.
DSP Best Practices
Apply DSP blocks only as needed. Run a test of your system without DSP, and then add processing as needed to fix any
issues that you hear in the audio signal.
Unless you encounter video that lags behind audio, set Delay to off.
DSP blocks do not affect whether the automixer gates a channel on or off.
Acoustic Echo Cancellation
In audio conferencing, a far-end talker may hear their voice echo as a result of a near-end microphone capturing audio from
loudspeakers. Acoustic echo cancellation (AEC) is a DSP algorithm which identifies the far-end signal and stops it from being
captured by the microphone to deliver clear, uninterrupted speech. During a conference call, the AEC works constantly to opti
mize processing as long as far-end audio is present.
When possible, optimize the acoustic environment using the following tips:
Reduce speaker volume
Position speakers farther from microphones
Avoid pointing speakers directly at microphone coverage areas
Selecting a Reference Signal for AEC
To apply AEC, provide a far end reference signal. For best results, use the signal that also feeds your local reinforcement sys
tem.
