Perfect, thank you.

HI @John Mulcahy

My TRINNOV ALTITUDE CI has these filter settings at 192/24:

Filter Type:

• The peak notch: Parametric equalizers are multi-band variable equalizers which allow users to control the three prima-
ry parameters: amplitude, center frequency and bandwidth.

• The shelving high (1st or 2nd order): High shelving filters cut or boost all frequencies equally above a desired cutoff
point.

• The shelving low (1st or 2nd order):Low shelving filters cut or boost all frequencies equally below a desired cutoff point.

• Frequency: the center of the frequency range to be cut or boosted

• Gain: the amount of boost or cut (in dB)

• Q: the «sharpness» of the boost or cut. Higher Q meaning a narrower filter (not available for shelving second order)

• Order (Only available for High and Low shelving filters): The order of a shelving filter is changing the shape of the curve.

What REW EQ type matches the CI closest in REW? (from the dropdown), and if there is an easy way to import an EQ made via REW to flatten the speakers before calibration to the ALTITUDE besides manually input??
Also, any way I can import a house curve designed in REW into the ALTITUDE CI easily?

Thanks, you are appreciated!

I don't know what Q configuration Trinnov uses, you can find out by measuring the filter shapes it produces with different settings on a line output and seeing what configurable equaliser setting produces the same shapes. You might find answers to the other questions on threads about the Ci, such as this one.

This may have been brought up previously, although a quick search didn't show it. My apologies if I'm being redundant.

Have you considered activating "hog mode" for the macOS version? This is roughly the equivalent of Exclusive Access mode in Windows. It bypasses a lot of the macOS audio system so that the app can change various interface settings like Sample Rate from within the app without using Audio MIDI Setup, and it avoids the resampling that macOS will perform if sample rates don't match. The other benefits of Exclusive Access generally apply, too.

I am *NOT* a software guy, so I don't have a clue about how much effort this would take. But, from a user perspective I think that the same options in Preferences as found in the Windows version with Exclusive Access on the external sound devices would be really helpful.

Once again, thank you for a very valuable and useful application.

That's outside the scope of REW. Low level access to interfaces is handled by code the Java runtime loads, it is possible to substitute that as @phofman did for WASAPI Exclusive and Linux ALSA PCM using his csjsound-provider project, something similar would be needed to improve the macOS interface access.

Understood - thank you.

John, hello. In the 'All SPL' tab, I want to move one graph a few dB without touching the second. I selected the first one by double clicking. It is marked with a thick vertical line. I right-clicked the action window and changed the SPL offset (dB). Both graphs are moving. Is this how it should be?

 

[dcibel]

Right click on the measurement itself in the left pane and adjust the offset there. Right clicking on the graph will adjust level for everything actively shown on the graph.

Thank you. It worked.

Builds updated today (beta 133) with these changes:

• Added: AirDSP by Acoustas equaliser entries
• Changed: siggen.properties has an entry for the signal generator frequency tooltip
• Fixed: dBFS data of minimum phase response could be 3 dB lower than the source
