AutoEq is a project for automatically equalizing headphones. While this project is now familiar to many people engaged in headphone hobby, it has always been a bit of a pain to use if you want anything else than the pre-computed presets. autoeq.app is a web app using AutoEq but now with a...

I present to you abxtests.com, a browser based app for double blind AB and ABX listening tests. This is effectively Listening Tests as a Service, meaning you'll be able to create your own listening tests easily and share it with other people. The primary target user would be an audio scientist...

Speakers can be virtualized (simulated) with headphones very convincingly with impulse responses and convolution software. This however requires the impulse responses to be measured for the individual listener and headphones. I'm trying to achieve this. I made impulse response recordings by...

I started looking into headphones about a year ago and got pretty soon excited about possibilities of using equalizer to improve headphones. Then I got very disappointed of the lack of existing headphone eq settings. Disappointment turned into resolution and this was my reaction. Now I'm exited...

I've been working on equalizing headphones based on frequency responses. So far I am compensating the response for harman target, inverting the response, limiting maximum gain and smoothing out sharp edges introduced by gain clipping. What should I take into consideration when producing the...

There seem to be popping up new headphone manufacturers doing hearing test based equalization. As far as I know these are divided into two groups: ones that are using hearing test with user input while testing for hearing thresholds and the ones that are using otoacoustic emission test. The...
