Everything you need to get the most out of Echo Equalizer. From first launch to advanced tuning.
Last updated: March 13, 2026
Getting Started
Five steps to your best sound in under a minute.
Enable an audio effect
Open Echo Equalizer and turn on at least one effect — Equalizer, Bass Boost, or Virtualizer — before opening your music player.
Play your music
Open your favourite music player. Echo automatically connects to the currently playing audio session. Most players work seamlessly out of the box.
Fine-tune your sound
Return to Echo Equalizer to adjust EQ bands, Bass Boost intensity, 3D Virtualizer width, or any other setting to your liking.
Use headphones for best results
While Echo works with speakers, headphones let you hear the full detail of your adjustments — especially the Virtualizer and stereo effects.
Close the app to turn off effects
When you're done, closing Echo will stop all audio processing and free up system resources.
Echo automatically connects to the currently playing music player. While most players work seamlessly, some might need additional configuration or may not support external equalizers. Check the Troubleshooting Guide for supported apps.

The Equalizer lets you customise sound frequencies with precision. Choose from 5, 7, 10, or 12 frequency bands — each slider corresponds to a specific frequency range covering bass, mid-range, and treble.
- Raise sliders on the left side to boost bass frequencies for genres like Hip-Hop or EDM.
- Raise sliders on the right to bring out treble and vocal clarity.
- Use the middle sliders to shape the mid-range — great for making vocals stand out.
- Includes preloaded genre presets like Folk, Dance, EDM, Heavy Metal, and more.
- Create and save your own custom presets for instant recall.
Tip: Start with a preset close to your taste, then fine-tune individual bands. Small adjustments often make the biggest difference.
Also known as the Sound Amplifier, the Volume Booster safely increases overall audio loudness beyond your device's standard maximum without compromising quality.
- Ideal for quieter audio recordings or podcasts that need a volume bump.
- Great for noisy environments where your device volume isn't enough.
- Works alongside the Equalizer for combined shaping and amplification.
Tip: Pair the Volume Booster with the Limiter to push volume higher while preventing distortion.
The Bass Booster specifically targets and amplifies bass frequencies, giving your music a deeper, richer, and more powerful feel. Ideal for EDM, Hip-Hop, and Rock.
- A single slider to control bass intensity — simple and effective.
- Works independently or alongside the Equalizer for layered bass control.
- Be careful with high settings — too much bass can cause clipping on some devices.
Tip: If you hear distortion at high bass levels, lower the Bass Boost slightly and use the Equalizer's low-frequency bands for finer control instead.
The 3D Virtualizer creates an immersive, surround-sound-like experience from any standard stereo audio source. It uses advanced audio processing to produce a broader, more spacious soundstage.
- Perfect for movies and gaming to feel more immersed in the action.
- Widens the stereo image so audio feels like it's coming from around you.
- Subtle settings often work best — high values can sound unnatural with some audio.
Tip: Use headphones for the best Virtualizer experience. Speaker output varies by device hardware.
The Advanced Limiter gives you professional-grade control over your audio's dynamics. It prevents distortion (clipping) while maximising volume, so your audio stays clean even at higher levels.
- Attack & Release Time: Control how quickly the limiter reacts to loud sounds and how fast it lets go.
- Ratio & Threshold: Fine-tune how aggressively the limiter kicks in and at what volume level.
- Post Gain: Apply a final volume boost after limiting to recover perceived loudness.
Tip: For casual listening, leave the Limiter on default settings. It quietly prevents distortion in the background.
The Compressor reduces the dynamic range of your audio — it brings louder parts down and quieter parts up, creating a more consistent listening experience.
- Great for podcasts or audiobooks where volume can fluctuate between speakers.
- Smooths out sudden loud peaks in music for a more relaxed listen.
- Works alongside the Limiter for a complete dynamics processing chain.
Channel Balance adjusts the volume distribution between left and right audio channels. Moving it to the left makes the left channel louder, and moving it to the right makes the right channel louder.
- Correct hardware imbalances in earbuds or headphones where one side is louder.
- Adjust for your environment — shift balance toward the ear facing away from noise.
- Accessibility support for users with hearing differences between ears.
Profiles are customised sound settings you can save and switch between. Create profiles for different headphones, moods, or genres — and even auto-apply them when connecting specific Bluetooth devices.
- Tap "Current Profile" or select "Save As Profile" from the menu to save your setup.
- When a profile is applied (manually or automatically), it remains active even after you disconnect.
- Auto-apply profiles to specific devices like car Bluetooth, gym headphones, or home speakers.
Tip: Create a profile where only the Bass Boost is enabled but set to 0% to keep the background service active without changing the sound.
important tips.
Keep these in mind for the best experience.
Disable Battery Optimisation
Go to Echo Equalizer Settings and tap "Disable Battery Optimisation". This ensures the app runs smoothly in the background without being killed by your device's battery saver.
Effects Must Be Active
Disabling all effects will stop Echo's background service to save battery. At least one effect must be enabled for audio processing to work.
Backup & Restore
Echo supports backing up your profiles and settings so you can restore them after a device reset or when switching to a new phone.
The key? Experiment.
The best audio experience comes from trying different settings and combinations. There's no single “perfect” setup — it's all about what sounds best to you.
