Equalizer Buddy is a 20-band equalizer designed for earphones with multiple drivers. It offers two methods to calibrate your earphones - by frequency response curve and by tone generator.

Calibration with ease:

By FR Curve - You calibrate the earphones with a single image of your earphones' Frequency Response curve (raw or compensated). The process takes only a few steps and the interface is user-friendly. You can even customize your own Target Response curve if standard human target does not satisfy your need.

By Tone Generator - You listen to tones of different sound frequencies and balance their volume to create a "flat" response.

Designed for multiple driver earphones:

In Equalizer Buddy, band frequencies are customizable such that equalizer bands can be assigned to where they are needed the most. In Equalizer Buddy's Multi-driver-earphone Frequency mode, more bands are assigned to upper midrange and treble (i.e. frequency > 2kHz), where uneven frequency response peaks and valleys often occur in earphones with multiple drivers.

Say no to sibilance:

Unlike standard equalizers, Equalizer Buddy's treble band frequencies can be selected in a way such that frequency above 10kHz can be raised to create an airy feeling while sibilance / piercing sound at around 8kHz to 10kHz can be suppressed at the same time.

What music players does Equalizer Buddy support?

Equalizer Buddy only supports music players which "start audio sessions in android system" like Google Play Music, Musicolet, etc. If you can't see your music player being detected, please try removing the player app from recent history first. (Press the phone's square button once and then swipe.)
