I'm curious, did you make a comparison if the tone match was able to be as precise as the original IRs?
Good question! Perhaps Cliff will chime in to clarify some probobly wrong assumptions i did: I only ABed by ear using mid-price In-Ears. Perhaps you want do that for yourself.
If i remember correct, TMA Hires = 1024 points. The other question is: What resolution will have the UR-IR export of that tonematch? In my understanding the measurment based on the RAW8k samples (like IR capture also) to be capable to export TMA as (reasonable) UR-IR. So, export function will support UR-resolution, as long the measurment data is in the 8KRAW cache?! Because after saving TMA, switch Axe-Fx off and on again, the cache should be deleted and a preset is not large enough to contain the 8KRAW data?! That assumed, audition the TMA should be less accurate than audition the UR export from the TMA measurment in comparison to the primary IR-Mix ... hmm ...
Another thing is perhaps the accuracy of my TMA measuring method. I did use synth-block 3rd voice sine, frequency to LFO with slow rate and TMA time to PeakHold. While the Synth Sine from voice 3 can be 20Hz - 20kHz it should be fine. But viewing the plot, something weird seems happen below 40Hz:
NOTE: The purple frequency response shows (logical) NOT UR, but HiRes conversion to .wav (via JoJo`s converter). First assumption refering to the weird 40Hz and lower department: Converter works not accurate. Validation that the conversion is correct:
Green line = Capture of a simple speaker emulation with Voxengo Deconvoler
Blue Line = Voxengo IR via CabLab converted to -> HiRes.syx -> via JoJo converter re-converted to .wav
Result: JoJos converter works like a charm.
Red line: UltraRes conversion from original Voxengo IR, re-captured with TMA, exported as HiRes, reconvert via JoJo to .wav.
Result: Here it happens! Two theorys why: 1) My measuring method lacks (TMA settings, sine sweep from synth lacks, whatever) 2) IR export or TMA Block trims "to much". Some offset thingy... If i remember correct, Cliff refine the trim-algorithm to prevent some issues, when tonematching outboard gear or so....
Anyhow: From judgement with my ears i would say: Super accurate! And that`s what counts to me at the end....
PS.: After tonematching your two CabIRs into one i thought i`ve done something wrong looking to the TMA plot. Cliff stated earlier: Window shows +/- 20db, vertical dots represent 2db. I tried to find a similiar window in RoomEQ Wizard and ask me:
Did the TMA screen shows not bandwidth 20Hz to 20kHz, but something like 100Hz to 10kHz?:
Cliff, hopefully you will bring some light into the dark ... ?
Sorry for getting a bit OT :roll
[EDIT] Meanwhile i believe the TMA window bandwidth is scaling depending on the frequency response... would make sense... i don`t know ...
