AutoEQ ~ Automatic Headphone Equalization


AutoEQ is a project for equalizing headphone frequency responses automatically and it achieves this by parsing frequency response measurements and producing a equalization settings which correct the headphone to a neutral sound. This project currently has almost 2000 headphones covered in the results folder. See Usage for instructions how to use the results with different equalizer softwares and Results section for details about parameters and how the results were obtained.

AutoEQ is not just a collection of automatically produced headphone equalization settings but also a tool for equalizing headphones for yourself. frequency_response.py provides methods for reading data, equalizing it to a given target response and saving the results for usage with EqualizerAPO. It’s possible to use different compensation (target) curves, apply tilt for making the headphones brighter/darker and adding a bass boost. It’s even possible to make one headphone sound (roughly) like another headphone.

Third major contribution of this project is the measurement data and compensation curves all in a numerical format except for Crinacle’s raw data. Everything is stored as CSV files so they are easy to process with any programming language or even Microsoft Excel.

foo_dsp_dolbyhp ~ Foobar Virtual 5.1 Headphones


Dolby Headphone technology gives you the sound of a 5.1 surround system through any pair of headphones.

It accurately models the surround sound listening experience of a properly set up and calibrated 5.1-channel speaker system, making it ideal for personal and portable surround listening.

This component wraps the functionality of a Dolby Headphone engine DLL (typically DOLBYHPH.DLL bundled with some software DVD players) to be used under Foobar2000. After installation you must configure the plugin pointing out the location of that DLL in your system and restart foobar2000. Amplification is provided by the Dolby Headphone engine itself.

bs2b ~ Bauer Stereophonic-To-Binaural Headphone DSP


A typical stereo records are being made to listen by speakers. That is a sound engineer makes the stereo mix to the adaptation of sound for listening of one channel by both ears. Therefore, you will be tired during a long time headphone listening more by a super-stereo effect than by a poor design of headphones. What’s missing in headphones is the sound going from each channel to the opposite ear, arriving a short time later for the extra distance traveled, and with a bit of high frequency roll-off for the shadowing effect of the head. And the time delay to the far ear is somewhat longer at low frequencies than at high frequencies. The Bauer stereophonic-to-binaural DSP (bs2b) is designed to improve headphone listening of stereo audio records…

M.R.O.: Headphone equalization


If a tonal linearity, natural head-phonic imaging, and Hi-Fidelity are what you’re looking for, search for headphones matching the above reference DF curve the most.
… BTW, the most accurate DF equalized headphones in the market is ER-4 from Etymotic Research …
