I ordered the UMIK mic. A few questions on this. I can take all the measurements (maybe with some guidance!), but can the Audessey editor app make changes not being a PEQ? I feel like I'm better off letting a professional do the calibration, is this something that can be done remotely? If so, any recommendations?
In my opinion the Editor App approach is better than PEQ, because with PEQ, such as with Yamaha's YPAO, you have to know what you are doing, like figuring out the best "Q" values and the number of filters you can create are very limited.
With the Audyssey App, you are basically giving Audyssey feedback as to what the actual results are after the Audyssey run so that Audyssey can re-do the filters for results closer to the original target. If you repeat the process (using REW) enough times, you will end up with a non flat target curve but a much flatter actual curve as measured by REW. So using the App, Audyssey is still in charge of creating the FIR filters, based on your input. FIR filters are inherently "better" (in relative term, and can't really generalize) than the IIR filters that YPAO and AARC (Anthem ARC) are based on. Anthem does have a new version so may be they are now "better" in some way.
In addition, my understanding of how the App work is (or could be just my imagination, or educate guess at best):
- Audyssey uses an ideal, flat target curve to create a set of filters.
- The filters created failed to achieve the goal, so the actual curve (not what the App, or the AVR show you, but the one you measured with REW and the Umik-1 mic. There are various reason outside the scope of this thread I guess.
- With the App, you can customize your own curve, so now you have the following 2 choices but not limited to just those two:
1) Just edit the curve to you taste and hope Audyssey will follow that curve, and you reached you goal, but you won't know until you measure it with REW, or
2) Don't just trust Audyssey 100% but use REW to verify the actual results and then use the App for improvements. If that's what you wish to do then you can basically try the following summarized steps:
a) Compare the original results after the Audyssey run as shown in the REW FR graph, with the flat curve (I would suggest choose the range from 20 Hz to about 200 Hz, but its your choice). Calculate the different offsets required, to bring the post Audyssey actual results.
b) Enter the required offsets (the theoretical numbers, by calculations) for say at least 20 frequency points for the 20-200 Hz range.
c) Save the file back to the App and then send it to the AVR.
d) Measure with REW again and compare the actual FR to the flat curve.
e) If the improvement is not good enough to you, then repeat the steps until you are happy or give up and accept the results as the best you can do, given the time you are willing to spend on this.
f) Now that you have a reasonably near flat curve, you can enter a few frequency points to increase the low bass gradually from say 120 Hz to 20 Hz if it is the so called "Harman" curve you prefer.
For steps b) and the subsequent repeats of the same, you should use the freeware Ratbuddyssey unless you are really good in drawing the curve directly on the screen with you fingers or touch pen.
If you are willing to follow the steps above, there is an Audyssey Editor App user's thread already:
