Layer and overlap audio tracks so they play together, and balance each one with its own volume — a real audio mixer that runs in your browser. Mix songs, beats and voice, then export one file. No upload, no software, 100% private.
Layer unlimited tracks
Stack as many tracks as you need so they all play at the same time — the core of any audio mixer.
Per-track volume
Each track gets its own volume slider to balance the mix — bring one up, push another back.
Voice + music
Put music behind a voiceover or a vocal over a beat, with the levels set exactly how you want.
Mix any format
Combine MP3, WAV, FLAC, OGG, M4A and AAC in one mix and export to your chosen format.
Open the mixer in Mix mode
Launch the Audio Joiner and switch to Mix mode so tracks are layered instead of played end-to-end.
Add your tracks
Drop in the songs, beats or voice recordings you want to combine. Different formats mix together fine.
Set each track's level
Use the per-track volume sliders to balance the mix — the heart of mixing audio.
Preview and export
Listen to the blend, fine-tune, then download a single mixed file — processed locally, no upload.
An online audio mixer lets you layer several audio tracks so they play at the same time and balance their levels — like a mixing console, but in your browser. DefyAudio's mixer overlays your tracks, gives each one its own volume slider, and exports a single combined file.
Open the DefyAudio mixer in Mix mode, add your tracks, and they're layered so they play simultaneously. Adjust each track's volume, preview the blend, then export — free, private and entirely in your browser.
To overlap two audio files so they play at the same time, open the DefyAudio mixer in Mix mode and add both files. They're overlapped automatically — set each track's volume to balance them, preview, and export a single combined file. It's free, and nothing is uploaded.
Yes. Every track in the mix has an independent volume slider, so you can duck the music under a vocal, lift a quiet part, or balance tracks recorded at different levels before you export.
Yes — the DefyAudio audio mixer is free with a free account and adds no watermark to your mix. It runs on any modern browser.
No. All mixing happens locally in your browser, so your audio files never leave your device.
MP3, WAV, FLAC, OGG, M4A and AAC — you can mix different formats in the same session and pick your output format when you export.
