What the TuneBad DAW is
A DAW is the software musicians arrange audio in. This is a free one that runs in a browser tab: put up to 12 songs on a single timeline, see every waveform, drag one so it overlaps another, cut and split anywhere, then export as MP3 or WAV. Nothing is uploaded — the audio is decoded and mixed on your own machine.
It exists for beat switches. Two songs playing over each other for a few bars is the whole trick, and it needs a timeline you can see — which is the one thing a single-file editor cannot give you.
How to make a beat switch
- Drop two songs in. They land one after the other, and each draws its own waveform.
- Drag the second one left until it sits over the end of the first. Both keep playing through the overlap — that is the switch.
- Press Crossfade to fade one out as the other comes in, or type your own fade lengths. If the two tempos disagree, Match stretches the second clip onto the project grid.
- Ride the speed, reverb and phone effects while it plays if you want the performance recorded, then export as MP3 or WAV. The file is the mix you just heard.
Which tool do you actually need?
| Tool | Use it when |
|---|---|
| TuneBad DAW | Songs need to overlap, or you want to hear the transition before you export it. |
| Audio Joiner | Files just go one after another, with no overlap. |
| MP3 Cutter | One file, and you only want to keep one region of it. |
| Slowed+Reverb | One file, and the whole thing gets the same slowed or nightcore treatment. |
Frequently asked questions
How do I make a beat switch?
Drag the second song so it starts before the first one ends — both play through the overlap. Give the first song a fade-out (or cut it with S) right where the switch lands, and hit Record moves if you want to slow it down live at the moment it flips.
Do the live effects end up in the export?
Yes. Press Record moves, perform your speed, reverb, and effect changes while it plays, and the take is replayed into the file when you export. Without a take, the export uses the current knob positions.
Is anything uploaded?
No. Decoding, playback, mixing, and export all run in your browser. Your songs never leave your device.
The two songs are different tempos — now what?
Every clip gets its tempo detected and shown. When it does not match the project, a Match button appears: it stretches that clip to the project tempo without changing its pitch, then slides it so its downbeat lands on the grid. The BPM is editable, with one-click halve and double, because tempo detection is an estimate and gets the octave wrong on fast tracks.
Will I lose my work if I close the tab?
No. The arrangement and the songs themselves are saved in this browser as you work, and the timeline comes back when you return. Clear session wipes it whenever you want. Nothing is uploaded — the files never leave your device.
