v5.1.2 Free — unlimited single-song exports code LAUNCH30 = 30% off any tier

Any song. A Dead as Disco track. In 20 seconds.

Drag in a file — or a whole folder — and DiscoForge writes finished, game-ready tracks straight into Dead as Disco. It locks the downbeat, handles songs that change tempo, and skips the in-game Advanced Editor entirely.

The BPM is the easy part.

Looking up one song's BPM takes 30 seconds. Aligning the downbeat by ear, fixing half/double-time guesses, handling tempo changes, and doing it for every song in your library — that's the part that eats your afternoon. DiscoForge automates all of it.

Without DiscoForge

  • Press "Add My Music" and select your audio file
  • Look up the BPM — quick when Tunebat has the song, slow when it doesn't
  • If BPM is below 100, double it (game requires 100+)
  • Enter the Advanced Editor and find the first downbeat by ear
  • Nudge the offset slider until the metronome clicks on-beat
  • Test in-game — if the importer guessed half/double time, it drifts
  • Re-align, re-test, then repeat for the next song
  • Fine for one easy track — a grind across a library, and tempo-change songs fight you the whole way
~20 sec per song

With DiscoForge

  • Step 1: Drag the audio file onto DiscoForge
  • Step 2: Wait ~20 seconds while it analyzes
  • Step 3: Click Export
  • Step 4: Song is in the game, synced to the beat
  • ~20s per song

Unlimited exports free. No key. No commitment. If it saves you time, pick a tier that fits.

Start Free Trial — No Card Required

Built from in-game testing.

Librosa-based analysis with octave-error correction. Built by testing against the game's actual import engine to match the format the game expects.

Octave-error correction

Librosa's beat tracker loves to return half or double the real BPM. DiscoForge scores three candidates against onset alignment and picks the right one. In testing, ~70-85% of songs detect correctly on the first pass — electronic/dance with strong kicks perform best.

First-downbeat detection

Onset detection finds the first strong hit and back-calculates the signed millisecond offset. Clamped to the game's ±250 ms range automatically.

Smart tempo sections

Sliding-window BPM analysis emits a section only if a cluster spans 8+ seconds AND differs from surrounding tempo. Capped at 5 sections so the game doesn't silently drop your song.

Drag, drop, batch Standard

Drop one file or queue a folder. Batch mode processes everything while you do something else — auto-converts to Ogg Vorbis on the way out. Available on Standard and Source tiers.

In-app updater

All tiers get lifetime updates — every new release included free, forever. The app notifies you on launch and updates in one click.

Free, no limits

Unlimited single-song exports without a key. No watermark, no time limit, no export cap. Use the full workflow — analysis, editor, preview, export — forever, free. Upgrade to Standard for batch, watch folder, and unlimited library.

Frequently asked questions.

Yes. Unlimited single-song exports without a license key — no watermark, no time limit, no export cap. The full single-song workflow (analysis, editor, preview, export) is completely free forever. Batch export, watch folder, and unlimited library require a Standard license. Try your whole library — you'll only need to upgrade when you want batch or watch-folder convenience.
In testing, ~70-85% first-pass accuracy across a mixed library. Electronic and dance tracks with strong kicks detect most reliably. The UI shows a confidence score and lets you override the BPM with one click. Triplet-feel grooves, shuffle rhythms, and live recordings are the main failure modes — you can fix those with the manual BPM override.
Lite is free forever with the full analysis engine and unlimited single-song exports. Standard adds batch export, watch folder, an unlimited library, access to the buyer Discord channel, priority feedback, and roadmap input. Exports and updates are free for all tiers — Standard unlocks power-user workflow features.
Download the .exe from any tier (Lite is free). Launch it, drag an audio file onto the window, wait ~20 seconds, click Export. Your song appears in Dead as Disco's ImportedSongs folder. No key needed — the full single-song workflow is unlimited and free.
The compiled binary is Windows-only right now. The Source tier ships full Python — runs on Mac and Linux if you set up the librosa + PyQt6 environment yourself.
Standard and Source: refunds within 30 days at my discretion, just email. Lite is free so there's nothing to refund. Gumroad handles all transactions.
No. DiscoForge is an unofficial fan tool. Not affiliated with Brain Jar or Dead as Disco.
Every tier ships a single-file .exe (~170 MB) with no install required. First launch takes 10-30 seconds while Windows extracts the bundled Python runtime — instant from then on. No admin rights, no registry changes.

Three tiers. Pick what fits.

Lite is free forever — no export cap, no time limit, no subscription. Standard and Source are one-time payments for lifetime access to advanced features.
