Join songs, voice notes and recordings into one file — trim each part, crossfade, even out volume and save MP3, M4A or WAV. Free, no signup, and your audio never leaves your device.
MP3, WAV, M4A, OGG, FLAC or voice notes — up to 20, mixed freely.
🎵 Drop 2–20 audio files here, or tap to choose
MP3, WAV, M4A, OGG and more · drag the waveform edges to trim
Crossfade blends each clip into the next; the clean-up options are made for voice recordings.
MP3 plays everywhere; M4A is smaller at the same quality; WAV is lossless for editing.
Drop MP3, WAV, M4A or voice-note files onto the box — they appear with a waveform each.
Use ▲ ▼ to set the order and ✕ to remove one. Drag a waveform’s edges (or type Start and End) to trim; set each track’s volume, or mute part of it.
Choose crossfade, gaps and fades, and switch on Even out volume or Remove silence if you need them.
Pick MP3, M4A or WAV and a quality, press 🔀 Merge audio, listen to the result and download.
💡 Tip: Mixing songs? A 2–3 second crossfade makes the join seamless. Joining speech? Leave crossfade off and turn on Even out volume.
Combining audio used to mean downloading an editor, learning its timeline and exporting through three menus. For the common case — put these recordings together in one file — that is overkill. Drop your files above, arrange them, trim what you do not need and merge.
Like every free AIMerger tool, the audio joiner runs in your browser: your voice notes, interviews and demos are decoded, edited and encoded by your own device. Nothing is uploaded, which matters when the recording is a private memo, a client call or an unreleased track.
Just joining MP3s? The MP3 Merger starts with MP3 settings. Voice notes? The Voice Recording Merger has the clean-up switched on.
Drop both files into the tool above, set the order and click Merge audio. Choose MP3 as the format and download one combined MP3 — free, no signup, nothing uploaded.
Anything your browser can decode: MP3, WAV, M4A/AAC, OGG/Opus, FLAC and more, mixed freely. Save as MP3, M4A or WAV.
Yes — switch on “Even out volume” and quiet and loud tracks are brought to a similar level without clipping. You can also set each track’s volume by hand.
Yes. Drag the edges of any waveform to trim, and choose a crossfade of up to 5 seconds between tracks.
Up to 20 files per merge; the only length limit is your device’s memory.
No. Decoding, editing and encoding all run in your browser on your own device — your audio is never sent anywhere.
Everything on AIMerger brings things together — here is what pairs with this one.
