Adjusting the equalizer from an external device

Question

Audio

There is a PC with Win7 and an ASUS Xonar DX audio card, as well as a player with a well-tuned equalizer. It is necessary to programmatically analyze the sound from the player and set up the equalizer on the PC (for example, in AIMP3) so that the PC produces exactly the same sound. What program can do this?

Answer 1

RMAA
This program will generate an audio file to be played on the player and on the computer. You connect your player/computer's audio output to your computer's line-in input, and run RMAA in analysis mode. The program listens attentively to the test audio file and produces several graphs and numerical values. You need a single frequency response graph.

Answer 2

I have not seen such software, but as an option, you can try to record white noise (it has a flat frequency response), pass the output from the player through a spectrum analyzer. In theory, the equalizer will change the frequency response of white noise, which will be visible in the spectrum analyzer. And then already in the equalizer of the aimp, adjust the desired frequencies, reproducing white noise already on it.
Only headphones and computer speakers will still give a different sound. In general, such things are much easier to tune by ear, there are not so many bands in household equalizers.

Answer 3

In theory, you need to take a set of samples that have known frequencies, and then record with maximum quality in what form the player gives out, then you need to analyze how the sound produced by the computer differs from this and make adjustments.
However, it is not only and not so much the sound card that influences here, but the audio system and room acoustics.
IMHO, too specific task => if there is software, then a professional combine, and even more likely it is done by a separate hardware and software complex.
