Dirac Live Active Room Treatment

If you're seeing a warning about "imprecise measurements", or that the microphone is picking up a very low gain, here is a list of general tips and tricks which has helped other end users in the same situation. Try these tips in the following order:

• Make sure the microphone has been granted permission to be used by Dirac Live (this is the first and most important thing to check for Mac users). macOS System Preferences => Security & Privacy => Microphone => Dirac Live => ON

• Make sure the computer is not running any other heavy tasks while using Dirac Live.

• Insert the laptop charger cable before doing the measurement process.

• Check power / energy saving settings. Make sure the computer is not in any power saving mode.

• Turn off "enhanced sound" (any kind of spatial experience enhancing etc) in Win/Mac sound/audio settings.

• Mac users should turn off "Voice Isolation" and select "Standard" instead. This option can be found in the top right row of icons whenever Dirac Live is being used. More info about this feature: https://support.apple.com/en-gb/guide/mac-help/mchle82b42f0/mac

• Retry a measurement point a few times.

• If applicable, use another USB port for the microphone (some USB ports handle audio better than others). Always connect the microphone through a powered USB extension cable (not a USB hub).

• Change USB cables, they can be broken. An active/powered USB cable is recommended if longer than 5 meters.

• Try to go through the calibration/measurement process without loading the calibration file of the microphone.

• If your AVR comes with a bundled microphone, please try to perform the measurements with that one (not applicable with Denon & Marantz since their mic is only for Audyssey).

• Try another microphone or other audio cables for the microphone connection.

• Try another computer.
