How to Use
- 1Add your tracks — drag a few audio files onto the mixer or click to choose them. Each is decoded in your browser and added as a layered track (up to 6).
- 2Balance and shape each track — set its volume and stereo pan, shape its tone with the 3-band EQ, and add reverb for space. Use the master volume for the whole mix.
- 3Line up the timing — drag a track's waveform left or right (or type a Start offset) so each part comes in where you want, and mute or solo tracks while you check the balance.
- 4Preview from any point — press Preview mix to hear everything play together, and click or drag the timeline bar to skip straight to the spot you want to start from.
- 5Mix down and download — choose MP3 or WAV and press Mix & download to save the finished mix. Nothing is uploaded; it all happens on your device.
About This Online Audio Mixer
Guitar Tool Hub's free audio mixer layers several audio files so they play at the same time, right in your browser. Upload a few MP3, WAV, M4A, OGG, or FLAC tracks, then set each one's volume and stereo pan, shape its tone with a 3-band EQ, add reverb for space, drag it along the timeline so the parts line up, and mute or solo tracks while you balance the mix. Preview everything playing together, then mix down and download the result as a single MP3 or WAV. It's a focused mixer, not a full DAW — perfect for guitarists who want to put a vocal or second guitar over a backing track, double a rhythm part, add a bass line under a riff, or balance a quick demo. Because all decoding, mixing, and exporting happen locally on your device, nothing is ever uploaded. This is the layering counterpart to the Audio Joiner: the mixer stacks tracks to play together, while the joiner stitches clips end-to-end.

Frequently Asked Questions
Upload two or more audio files to the mixer, then set each track's volume and pan and nudge its start offset so the parts line up. Press Preview mix to hear them play together. When the balance sounds right, choose MP3 or WAV and press Mix & download. Everything happens in your browser — no upload.
The mixer layers tracks so they play at the same time (for example, vocals over a guitar take). The audio joiner stitches clips end-to-end so they play one after another. Use the mixer to combine simultaneous parts into one balanced track; use the joiner to chain clips in sequence.
Layer a vocal or a second guitar over a backing track, double your rhythm part for a thicker sound, drop a bass line under a riff, or balance a quick demo. Set each part's level and pan (e.g. pan two rhythm guitars left and right), nudge a take's start time so it lines up, then mix down to a single file to share.
Yes. Drag a track's waveform left or right to set when it comes in — for example, let an intro play before a guitar layer enters — or type an exact Start offset in seconds for precise placement. The waveform lane shows where each track sits on the shared timeline.
Yes. Each track has a 3-band EQ (low, mid, high) so you can carve space — for example, dip a guitar's mids so vocals sit on top — plus a reverb send to add ambience. Both update live while you preview and are baked into the downloaded mix. It's still a focused mixer, not a full DAW.
Mute silences a track in the mix; solo plays only the soloed track(s) and silences the rest, which is handy for checking one part on its own. Muted (or non-soloed) tracks are also left out of the final mixdown.
No. Decoding, mixing, and exporting all run locally in your browser using the Web Audio API. Your files are never sent anywhere, which keeps them private and means the tool works even on large files without an upload wait.
You can load MP3, WAV, M4A, OGG, FLAC, and most common audio your browser can decode (you can mix formats), and export the finished mix as a 192 kbps MP3 or a lossless WAV file.
Yes — completely free. No account, no download to install, and no payment required.
