Flat Equalizer - Bass Booster

What it does

Flat Equalizer - Bass Booster is an Android audio tool for adjusting how music and video sound on a device. It suits listeners who want more control than their phone’s built-in audio settings provide, whether that means shaping individual frequencies, adding bass, or applying a wider sound effect.

Controls and effects

• A 10-band equalizer lets you raise or reduce separate parts of the frequency range.
• A bass booster increases low-frequency emphasis, while the virtualizer adds a spacious, 3D-style effect.
• Reverb options simulate the character of different acoustic spaces.
• Genre presets, including Classical, Dance and Hip Hop, provide starting points for listeners who do not want to tune every band manually.

Day-to-day use

The interface uses a flat, uncluttered layout with slider-based controls. Light and dark themes are available, and the app is intended to process audio from music and video players across the device rather than serving as a player of its own. The result can depend on the phone, Android version and the app producing the audio, so playback behaviour is not necessarily identical on every device.

What to consider

More adjustment also means more opportunity to overdo it. Heavy bass or overall boosting can cause clipping or distortion, particularly when the source is already loud; modest changes are a safer starting point. Built-in equalizers from a phone manufacturer or another audio app may also interfere with the result.
