So now I double check even the distances and levels for each speaker with REW after calibration. I was quite satisfied with Audyssey calibration for years but the more I understand and utilize REW the less satisfied I have become with MultEQ-32. I wouldn’t know without measuring myself. They may also use a weighted pink noise that gives an artificial response shape. They might bypass the Audyssey eq filters for example. This may or may not work depending on the kind of pink noise built in and how it’s piped through the processing chain. That makes measuring through ATMOS nearly impossible.Ī better solution might be to see if the receiver has built in pink noise that can be sent to discrete atmos channels and using the RTA mode. The processor then decides which set of speakers get the sound with what level and eq. You send it to a geometric position in hemispherical space. They told me it is not possible to send discrete test tones to specific atmos speakers. The company I talked to specializes in ATMOS and DYS:X authoring and has the software needed. I looked at having a custom test disc authored with specific test tones and sweeps. For a contract I have with a manufacturer I actually looked into this. In addition, my understanding of how ATMOS works would make it hard to do.

There is not a way to send a test tone to those signals through something like Mulcahy can confirm, but it is my understanding that no software can send a signal with the meta-data to go to an atmos channel without purchasing a license through Dolby. Do you like it?Īs for measuring the eq filters of the atmos channels with Audyssey enabled, unless I’ve missed something big, you can’t measure that right now. That should be judged based on sound alone. They change the eq based on the level of the content. You really don’t want to measure through dynamic eq modes.
