Auto-level
One click measures the mix and lifts it to −1 dBFS peak level — studio loudness without doing the maths.
Audio Stem Mixer · im Browser
Your track.
Your edit.
Cut to picture.
For Ashfallmusic tracks that ship with stems, you mix in the ASM fully cleared stems yourself: balance them, cut clips with automatic crossfade, lay your own video over the top as a reference — and license the finished mix as WAV lizenzieren, with no collecting-society fees.
No software · video stays local · preview sounds like the purchase
The Ashfallmusic ASM is a browser-based stem mixer that tailors a track's individual stems to the length and pacing of your project. Instead of taking a track as it is, you decide: drums down, vocals out, intro shortened, the drop right on the scene change — with your own video running as a reference above the tracks. What you hear in the preview is exactly the file you license.
Stems
Every stem is yours to shape
Tracks with stems ship as Einzelspuren — for example drums, bass, melody and vocals. Every track has volume, mute and solo.
- Instrumental for voice-over: mute the vocals, done
- Drums back when the voice carries
- Solo for a quick listen to one stem
Schnitt
Cutting without clicks
Split clips at the playhead, move and overlap them — every cut automatically gets an inaudible crossfade, just like in a proper DAW. You drag fades in and out using the handles at the clip corners.
- Shorten the intro, put the drop on the scene change
- Loop passages with Ctrl+C/V
- Every step undoable with Ctrl+Z
Video reference
Your video above the tracks
Load your video as a Filmstrip track with a preview window — frame-accurate to the playhead. That way you cut the music straight to picture.
- No upload: the video stays local on your machine
- No storage, no waiting — even for large files
- Movable, with an original-audio switch
And the studio side? It runs itself.
Levels, curves and limiting are handled by the ASM in the background — you look after the edit.
Safety-Limiter
Protects against clipping — in the preview just as in the file you buy.
Detail-Zoom
The timeline zooms down to milliseconds and the waveform stays razor sharp.
60 steps of history
Ctrl+Z undoes any action — from a cut to a fader move.

Questions about the ASM
Is my video uploaded?
No. The video stays entirely on your machine and is only displayed locally in the browser — nothing is uploaded, stored or processed. That is why even large files start instantly. After closing the mixer you simply pick it again next time.
Does the purchased file really sound like the preview?
Yes, because both run through the same audio chain: the same levels, the same fade curves, the same limiter. The WAV export is not a rebuild of your mix, it is the same mix — simply rendered at full quality.
Do I have to budget for collecting-society fees?
No. The entire Ashfallmusic repertoire is fully cleared — it is not registered with any collecting society, neither for authors' rights nor for neighbouring rights. So no society fees apply to your licensed mix.
Is the finished ASM mix free of neighbouring-rights fees too?
Yes. The mix is built from the stems of a fully cleared track and stays that way. Ashfallmusic has the clearance confirmed contractually by the performers and rights holders involved. On request you receive written confirmation of that clearance for your records.
Do I need prior experience with a DAW?
No. Anyone who has edited a video before will find their way immediately: timeline, playhead, dragging clips. The studio side — crossfade curves, levels, limiting — is handled by the ASM automatically in the background.
What do I need to get started?
Just an up-to-date browser. You can try it without signing in; the video reference track and buying the mix require a free account.
