REW first scan - mystery

[SashaR]

All of AutoEQ's frequency response files

As for now - before your very helpful message - I was able to make PEQs for Android's ToneBoosters by using the AutoEQ and the REW's Configurable PEQ only. The following is an explanation from ToneBoosters of the correspondence of those REW filters that can be used to create 10-band PEQS.

... our filters are different from the ones in REW's table. The RBJ bandwidth/Q definition In this REW table [Configurable PEQ filters] is probably the best match that will work at low frequencies and mid frequencies, or in your implementations when using oversampling.

In Equalizer v3 of the ToneBoosters in the UAPP the 'Analog bell' is probably your best match for that peaking filter. In addition, Toneboosters equalizer v3 also supports a range of shelving, low cut, high cut filters but it seems you're only looking for the PEQ translation.

This note is true - but only because of restrictions of REW's Configurable PEQ .
Whether there are a ways to change the number of bands which REW will made in the GENERIC model EQ to be able use these filters in UAPP (and not be restricted to only the RBJ filters)?

Sweep length - is REW faulty on intel macbook?
My aim was to make a couple of PEQ settings to correct my room response in Wiim software.

At the beginning of this thread I was getting strange measurement drop-off going:

Mac > Airplay > Wiim mini optical out > SMSL M8 dac > Nord ICE 1200 > Revel 206 *1

I have tried changing the sweep length and it is giving quite different results.
I do also get some fails on the sweeps too.


1. Which of these setting for sweep can I trust?
2. Why is this difference occurring?
3. Will REW calculate PEQ settings, or do I have to rough estimate?
4. How would I verify the Wiim software PEQ is creating a more neutral response, do I save a sweep file and play it somehow from my iPhone Wiim app?


Very much appreciate if anyone has any ideas of best next step forward.

*1 I will also create a set not using Airplay and outputting from the headphone jack of the laptop straight into the Nord ICE 1200 amp which previously gave more believable result but have run out of time tonight.
