Audio Enhancer & Editor

Make every recording sound clear, loud and professional. Fexo brings you a complete audio enhancer app: a voice enhancer, noise remover and full audio editor and music editor in one. Everything is processed on your phone, it works offline, and your files are never uploaded, so your audio stays private.
✨ ONE TAP MAGIC ENHANCE
Tap once and the AI audio enhancer analyzes your file, repairs problems and delivers instant sound enhancement. Choose smart presets or save your own, set the strength with a slider, then hear the result with before and after compare. It is the simplest audio enhancer for android when you want to enhance audio quality in voice notes, interviews, lectures and songs.
🎙️ AI VOICE ENHANCER AND BACKGROUND NOISE REMOVER
The on-device AI (DeepFilterNet 3) is a true voice enhancer for recorded audio and a deep noise reducer that can remove noise from audio recording in seconds. Use it as a one tap background noise remover for speech, or take manual control: hiss and hum removal, de-click, de-ess, de-reverb, clarity, EQ, compressor, stereo width, pitch and loudness normalize give you studio grade noise reduction and complete background noise removal from audio and video.
🎬 ENHANCE AUDIO QUALITY IN VIDEO
Fexo is also an audio enhancer for video. The built-in audio extractor pulls the soundtrack out, the voice enhancer for video cleans it, and the app puts it back without changing resolution or frame rate. Use it for noise removal in video, to remove noise from video lectures and vlogs, or simply as a quick video to mp3 convert app when you only need the sound.
🎚️ AUDIO EDITOR AND VOICE EDITOR
A complete audio editing app with a multi-clip waveform timeline: trim, cut, split, copy, paste, merge, fades, gain, insert silence, shorten pauses, undo and redo with autosaved drafts. The audio cutter and merger handles podcasts, songs and voice notes, and one step podcast prep applies noise cleanup, leveling, voice EQ and compression to a podcast ready loudness target.
🎵 VOCAL REMOVER AND ISOLATION
Need a vocal remover for karaoke nights or covers? Remove or isolate centered vocals in stereo music in a couple of taps.
