Title: Room Correction: Bass Management for routing bass from speakers to subwoofer
Post by: stewart_pk on February 25, 2023, 09:25:34 pm

Hi, I'm using this feature and have a question.
The LFE [.1] subwoofer channel is typically mixed -10dB in content compared to the other speaker channels and must be boosted by 10dB to compensate and I do this is JRiver.
If one is using the Room Correction, Bass Management feature should speakers be reduced by -10dB before Room Correction in DSP Studio as to avoid the bass that is about to be Moved or Copied to the subwoofer channel being 10dB too high?
Or does JRiver do this automatically i.e. reduce all speaker channels (Non LFE [.1]) by -10dB before Room Correction, Bass Management and then increase all speaker channels (Non LFE [.1]) by -10dB after Room Correction, Bass Management?

the measured behaviour is described in https://wiki.jriver.com/index.php/Room_Correction#Bass_Management (NB: this is from a few versions ago so theoretically things can have changed since then)

Thanks, so from you first link I take it that's a YES, JRiver does lower the speaker levels by 10dB.
