System Equalizer Pro is not an equalizer buried inside one music player — it attaches to the audio output of the device itself. Streaming music, YouTube, games, radio, podcasts and audiobooks are all shaped by the same settings. No root required: switch it on once and it keeps working.

Phone speakers are thin on bass and cheap earbuds bury the vocals. A 10-band equalizer and a full set of effects close those gaps.


【Perfect for】
• Improving music, video and game audio all at once
• Earbuds or headphones that lack bass
• Bringing speech and lead vocals to the front
• Punchy bass at low night-time volume
• Anyone tired of readjusting between speaker and Bluetooth


【Main features】

►10-band graphic equalizer
31Hz to 16kHz, every band over ±12dB, with a live curve and a ±12dB preamp.

►19 built-in presets
Flat, Rock, Pop, Jazz, Classical, Hip-Hop, Electronic, Dance, Metal, R&B, Acoustic, Vocal, Podcast, Movie, Game, Night, Bass Boost, Treble Boost, Loudness. An edited preset is marked, so you can always go back. Save your own curves by name (one free, unlimited with Premium).

►Bass boost and treble boost
One knob each for the low and the high end.

►3D surround (virtualizer)
Widens the stereo image for a more spacious sound.

►Volume boost, limiter and balance
Pushes quiet videos past the system maximum (50% free, 100% with Premium) while the limiter catches clipping. The left-right balance is adjustable too.

►Dynamic bass and loudness compensation (Premium)
Eases the bass lift as the volume rises, and restores bass and treble that thin out at low volume.

►Vocal boost (Premium)
Brings speech and lead vocals forward for films and podcasts.

►Tilt and compressor (Premium)
Lean the balance toward bass or treble, and narrow the gap between loud and quiet passages.

►AutoEQ headphone optimisation (Premium)
Measured curves from the AutoEq project (MIT licence) for 8,853 models, converted to 10 bands and searchable offline.

►Hearing test and personal EQ (Premium)
Lower each tone until you can only just hear it; the result becomes a curve for your ears.

►Spectrum analyser (Premium)
A live frequency display of whatever is playing.

►Automatic profile switching (Premium)
By output (speaker / wired / Bluetooth), by the playing app and by time of day; your manual choice returns afterwards.

►Automatic bypass during calls
Effects step aside for calls, including VoIP.

►See and control what is playing
Title, artist and artwork, with play, pause and track skip.

►Widget, quick settings tile, notification
Two widget sizes with the EQ curve and preset skip; the notification can be minimal or hidden.

►Diagnostics and test tone
Checks that the effects reach the output and that no other app has taken control.

►Six skins
Aurora, Ember, Nebula, Verdant, Mono and Sakura (Aurora free).


【Free, with no time limit】
Equalizer, preamp, 19 presets, one of your own, bass and treble boost, 3D surround, balance, limiter, 50% volume boost, call bypass, player control, widgets, tile and diagnostics.


【Premium is a one-time purchase】
Not a subscription. Buy once, nothing to renew or cancel; it carries over to your next phone on the same Google account.


【About permissions】
• Microphone: only if you turn the spectrum display on. Android requires it to read the output level; microphone audio is never used
• Notification access: only to show and control what is playing, never to read notifications
• Usage access: only for optional per-app switching
Nothing is recorded and nothing leaves your device.


【If you cannot hear a difference】
Some devices limit how effects apply to the whole output. Change "Connection mode" in Settings and run the diagnostics and test tone. Contact us before buying if it still does not work. ## Rankings - #991,737 — Overall ## Permissions and access ### Permissions - `android.permission.ACCESS_ADSERVICES_AD_ID` - `android.permission.ACCESS_ADSERVICES_ATTRIBUTION` - `android.permission.ACCESS_NETWORK_STATE` - `android.permission.FOREGROUND_SERVICE` - `android.permission.FOREGROUND_SERVICE_SPECIAL_USE` - `android.permission.INTERNET` - `android.permission.MODIFY_AUDIO_SETTINGS` - `android.permission.PACKAGE_USAGE_STATS` - `android.permission.POST_NOTIFICATIONS` - `android.permission.RECEIVE_BOOT_COMPLETED` - `android.permission.RECORD_AUDIO` - `android.permission.REQUEST_IGNORE_BATTERY_OPTIMIZATIONS` - `android.permission.WAKE_LOCK` - `biz.cloudex.android.equalizerpro.DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION` - `com.android.vending.BILLING` - `com.android.vending.CHECK_LICENSE` - `com.google.android.finsky.permission.BIND_GET_INSTALL_REFERRER_SERVICE` - `com.google.android.gms.permission.AD_ID` ## Similar extensions and apps - [Equalizer: Bass & Volume Boost](https://chrome-stats.com/d/com.equalizerapp.equalizer_app) — 25,975 users, 4.39 / 5 - [Bass Booster & Equalizer](https://chrome-stats.com/d/com.dakshdeveloper.bassbooster) — 33,209 users, 4.00 / 5 - [Sound Equalizer: Bass Booster](https://chrome-stats.com/d/droid.ninja.dheeraj.soundequalizer) — 29,787 users, 4.71 / 5 - [Echo Equalizer: Bass Booster](https://chrome-stats.com/d/com.hapibits.soundlift) — 708,913 users, 4.87 / 5 - [EQ Pro - Equalizer & Volume](https://chrome-stats.com/d/com.equalizer.music.mp3.player.musicplayer) — 1,534,521 users, 4.61 / 5 - [Equalizer & Volume Boost PRO](https://chrome-stats.com/d/equalizer.bass.volume.pro) — 49,975 users, 4.38 / 5 - [Bass Booster & Equalizer](https://chrome-stats.com/d/com.dakshdeveloper.equalizer) — 65,556 users, 4.18 / 5 - [Equalizer - Bass Booster Music](https://chrome-stats.com/d/com.bassboostermusic.soundspeaker.equalizer) — 2,131 users - [Smart Equalizer](https://chrome-stats.com/d/com.shotex.smartequalizer) — 1,045 users - [EQ Pro](https://chrome-stats.com/d/com.equalizer.music.mp3.player.booster) — 3,098 users, 4.75 / 5 - [Equalizer Pro](https://chrome-stats.com/d/com.zpp.music.equalizer) — 24,183,339 users, 4.53 / 5 - [Equalizer FX Pro](https://chrome-stats.com/d/equalizer.bassbooster.musicplayer.theme.pro) — 514,266 users, 4.27 / 5 --- Source: [Chrome-Stats](https://chrome-stats.com/d/biz.cloudex.android.equalizerpro)
