Here's what I did in my first attempt of using the Ratbuddyssey UI with the MultEQ Editor App:
1) Run Audyssey auto setup using the MultEQ Editor App.
2) Select the Ref curve, use REW to plot FR from you MMP for the range 15 to 120 Hz (as example only)
3) Set up an Excel, Google sheet, or the IOS equivalent spreadsheet to calculate boosts/cuts required quickly.
4) Pick a convenient target SPL based on the worse dips may have to ignore the sharp narrow room mode dips).
5) Select your anchor points for manual entries into Ratbuddyssey*
6) Enter the SPL values on the Y-axis that corresponds to each of the selected anchor point frequency.
7) Enter the calculated boosts/cuts required to bring the selected "anchor" points to the targeted levels.
* In picking your anchor points, try pick at least 30 points to cover the range 15 to 120 Hz (in this example)
You could try equal spacing (between frequencies) first and see how good the result look, or you can try picking about equal spacing, say every 3 Hz or even 5 Hz but always include the +/- peaks or near the peaks.
In your subsequent trials for fine tuning, always go back to the same REW reference FR graph, do NOT go by the new REW graph after your first trial adjustments have been made.
Below is an example of my reference REW FR plot (no smoothing!! for accuracy), and the Excel table shows the calculated (the "Adjustments" column) values for entering into the Ratbuddssey table.
I did not save the table that shows the 30 or so entries that got me within +/- 2 dB and the tabulated values I showed here were to be taken as an example just to show you how it looks.
Same for the Ratbuddyssey table, don't try to correlate them as I didn't do a good job in documented my many trial versions so they don't necessarily corresponds to each other.
Reference REW FR graph for picking the frequency points and the corresponding SPLs on the Y-Axis:
Enter the values to a spreadsheet table as show below, or you can do it manually but spreadsheets are much quicker.
|New target SPL||68|
|Freq on ref curve||SPL on ref curve||Distance from target||Adjustments|
Enter the necessary manual adjustments from the above spreadsheet table into Ratbuddyssey:
