Neumi BS5 with/without EQ "tilt" is incorrect #244

Open Plompudu opened 1 year ago

Plompudu commented 1 year ago

Describe the bug When looking at the Neumi BS5 in-room-Target "tilt" it's -10db@20kHz instead of the normal tilt

To Reproduce Steps to reproduce the behavior:

  1. Go to https://www.spinorama.org/speakers/Neumi%20BS5/ErinsAudioCorner/index_eac-v2-20211212-ported.html
  2. Click on Ref vs EQ
  3. Scroll down to Estimated in room
  4. See error

Expected behavior The Target Should be identical for with and without EQ

Desktop (please complete the following information):

Thanks. One of the autoEQ version didn't control the slope enough.

I am not sure the target should be the same. This one is likely bright in room. I ran the current optimiser and I got this:

filters_eq

Sounds better to me. WDYT?

If you are listening near field, then flat on axis is likely better.

filters_eq

Which one do you want?

Thanks!

I would prefer the flat on-axis. Could you do the same for the Sealed Measurement?
