AudioFuse: MP3 Merger & Cutter

Merge, cut, mix, split and convert audio — with results that sound right the first time.

AudioFuse is a fast, offline audio editor built around one promise: what you hear in the preview is exactly what you get in the file. Join tracks with no gaps, trim to the millisecond, blend voice over music, and export to MP3, M4A or WAV. Everything runs on your phone. Nothing is uploaded.

JOIN AUDIO — MP3 MERGER & AUDIO JOINER
• Combine two or more audio files into one
• Gapless by default: no added silence, no clicks between songs
• Optional gap or crossfade between tracks
• Mix formats freely — MP3, M4A/AAC, WAV, FLAC, OGG and more in one project
• Drag to reorder, trim each track before joining, preview every seam

CUT AUDIO — MP3 CUTTER & AUDIO TRIMMER
• Zoomable waveform with precise start/end handles
• Nudge by ±100 ms or ±1 s, or type the exact timestamp
• Fade in / fade out
• Make ringtones, alarm tones, voice clips and podcast segments

MIX AUDIO — VOICE OVER MUSIC
• Layer a voice recording over a music bed
• Per-track volume, start offset, fades and mute
• Preview the blend before you export

SPLIT AUDIO
• Split at positions you choose, into equal parts, or into fixed lengths
• Every part exported as its own file

CONVERT & EXTRACT
• Convert audio to MP3, M4A or WAV, at the bitrate and sample rate you pick
• Extract the audio track from a video as a standalone file

EXPORT YOU CAN TRUST
• Choose format, quality (128 / 192 / 320 kbps), sample rate and stereo/mono
• Every export is verified before you see "Success" — no half-written files
• Saved to Music/AudioFuse, ready for any player or file manager
• Large files are processed in streaming mode, so long recordings won't run out of memory
• Keep editing while the export runs in the background

PRIVATE & OFFLINE
• Works with no internet connection
• No account, no sign-up
• Your audio never leaves your device
• Original files are never modified — every edit creates a new file

MY CREATIONS
• Everything you've exported in one place
• Play, share, rename, or send a file straight back into the editor

Whether you're merging lecture recordings, cutting a ringtone, joining chapters of an audiobook, or laying a voiceover on a track, AudioFuse gets it done in a few taps — and the output is clean.
