i am looking for some digital room correction.
i already own a calibrated microphone and have set the equalizer with that, but i would like to use some digital room correction on top of that to further flatten my frequency response.
now i have seen some of the offerings.. so i really dont know what i am going to accomplish with this post.
coneq - $675 for the p8 version of the plugin and comes with the basic version of measurement software.
the basic measurement software doesnt allow for microphone calibration files.. a very huge problem.
the measurement software doesnt mention anything about a soundcard calibration file either.. which is apparently needed if you want FLAT (maybe the analog to digital convertor ruins the results of the digital to analog convertor.. i am not one to test each one in the circuit individually)
the basic measurement software samples at 48khz.. and that means your noise floor is gonna be higher, among other things you lose from having the DAC in a lower sampling frequency.
(all of my results show the DAC performance as far superior in higher sampling rates)
on top of all that, the cost is super expensive.
another option i was looking at: (((acourate)))
cost - $381.54 (340 euros)
i got an email explaining how to use a microphone filter file...
'Hi,
thanks for your interest in Acourate.
Please note that the demo version is just to get some feeling for Acourate but not to compute real filters.
But anyway you can import a microphone calibration file (*.txt format) with File - Read Amplitude - minphase and use it directly in the first step (macro1) of the room correction. The text file simply needs pairs of frequency (Hz) and amplitude (dB).

havent used to demo yet.. but the price is acceptable and you can use a microphone calibration file for that price.
a relatively high positive - acourate works in 24bit resolution / 96khz sampling rate
(havent opened up the software to see if there is a soundcard calibration file allowable)
another option i have read about: ARC system
this one costs $600 and comes with a microphone.
the website says the software works in 32bit with 96khz sampling rate.. but the microphone frequency response is only 20hz - 16,000hz
however.. when used with ARC, the calibrated frequency response is said to be 16hz - 20,000hz
some might see the condensor microphone as a downside since the mic preamp would have an affect on the final result.
the last one i have read about (and tried) is: Audiolense
the program allows for 32bit resolution / 96khz sampling rate
it supports ASIO
allows you to select the frequency correction width
you can change the time alignment.. i guess the filter adds whatever delay you specify.
and it also allows you to use a microphone calibration file (you can even view the microphone calibration in a frequency graph)
you can calibrate one speaker at a time or both speakers at once.
you can create whatever target curve you are capable of drawing.
its a pretty easy to use program.. cute and simple.
BUT.. i didnt notice any difference when using it.
i havent tried using the program without an already calibrated equalizer.. but will give it another go when i decide to try acourate.
i would really like to see an option that allows for soundcard calibration.
i mean, if we can have a microphone calibration file.. why stop there?
does anybody know of some cheaper options?
does anybody care to share how to add the soundcard calibration file to the mic calibration file so the entire input is calibrated before doing an analysis?
or maybe there is a digital room correction program that allows a specific place for soundcard calibration?
currently i am using foobar with the resampler at 96khz
i used the convolver plugin to load the generated correction file.
maybe some options or suggestions about using foobar with the convolver plugin?
