Your Track Sounds Great - Until It's On Spotify

AI music tools and home setups make finished songs in minutes, but the master is often too quiet, the vocals harsh, and the files not ready to publish. PD2AM closes that last gap.

Loudness that travels

Hit streaming-ready loudness (around -14 LUFS) with safe headroom, so your track sits at the right level on Spotify, YouTube, and Apple Music instead of sounding weak.

Vocals that sit right

Tame harsh sibilance, clicks, breaths, and AI artefacts with a gentle repair pass that blends most of the original back in, so the music stays faithful.

Files ready to publish

Export WAV and MP3 masters, embedded cover art, lyrics, stems, and a README in one delivery pack - everything a release needs, packaged in one click.

RACK, FIX, AI - One App, Three Jobs

Switch between mastering, repair, and AI delivery with a single click. The same track flows through all three.

RACK

Mastering Rack

An AI assistant analyzes your track - loudness, peaks, dynamics, spectral balance, stereo width, BPM, and key - then suggests a one-click preset like Gentle Polish, Balanced Master, or Smart Master. Build your own chain with Normalize (LUFS), reference matching, EQ, multiband compression, stereo widening, and format conversion. Preview 15 seconds, A/B against the original, then export.

FIX

Fix & Repair

Trim and fade with sample accuracy, add silent tail padding, and export just a clip when you need it. The Vocal Repair panel offers de-esser, declick, dropout fill, breath gate, AI vocal denoise, and a tilt-EQ vocal preset - each with its own strength slider. Compare two versions side by side to hear exactly what changed.

AI

AI Delivery

Read ID3 tags, embedded cover, and lyrics straight from your Suno/Udio MP3, align lyrics to a perfectly timed LRC with Whisper, and export a full delivery pack: WAV and MP3 masters for Spotify and YouTube, cover art, Demucs stems, a PD2V bridge file, and a README. Need a longer cut? The Track Extender loops a section seamlessly or generates new audio with AI MusicGen.

Everything You Need Between "Done" and "Published"

Mastering, repair, analysis, and packaging - built for music creators, not audio engineers.

AI Assistant & presets

Analyzes the track and detects its style, then proposes one-click mastering presets tuned to the genre - no guesswork.

Track diagnosis

Read loudness, peak headroom, dynamics, spectral balance, stereo image, vocal position, mud, tempo, and key at a glance.

Mastering pipeline

Normalize to LUFS, match a reference, shape EQ, multiband compress, widen stereo, crossfade, convert format, and tag ID3.

Vocal repair

De-ess, declick, fill dropouts, gate breaths, denoise with AI, and tilt-EQ vocals - each with an adjustable strength.

Stem separation

Split a finished track into vocals, drums, bass, and other stems with Demucs - perfect for remixes and clean re-edits.

Metadata & cover

Read and edit ID3 tags, embedded cover art, and lyrics, then align lyrics to a timed LRC file with Whisper.

Delivery pack

One click exports WAV/MP3 masters for Spotify and YouTube, cover art, stems, a PD2V bridge, and a README summary.

Track extender

Reach a target length by seamlessly looping a section, or generate new audio with AI MusicGen (experimental).

Real AI Models, Running On Your PC

PD2AM bundles open-source AI models so everything runs locally. A capable NVIDIA GPU makes them fast; a CPU fallback keeps them working.

Demucs - stems

Separates a mix into vocals, drums, bass, and other instruments for remixes, clean-ups, and re-edits.

Whisper - lyrics

Transcribes and time-aligns vocals so you get a perfectly synced LRC lyrics file from any song.

DeepFilterNet - denoise

Removes background noise and hiss from vocals and recordings while keeping the voice natural.

MusicGen - generate

Generates new musical audio to extend a track. Experimental, and for personal / non-commercial use only.

Note: most modules (Demucs, Whisper, DeepFilterNet) suit general use. The MusicGen model is licensed for non-commercial use only (CC-BY-NC), so AI-generated audio from MusicGen is meant for personal or experimental use. Loop-based extension and everything else stays free for your own releases.

Free to Use. Pro Removes the Watermark.

PD2AM is a companion to PumpyDumpy2Visual and shares the same Pro license. One subscription unlocks both apps.

Get PumpyDumpy2AudioMaster

A single Windows installer. Install, drop a track, and start mastering.

PumpyDumpy2AudioMaster v3.1.1

Windows 10/11 · 64-bit · single installer · ~3.1 GB

The download is large because the AI models (PyTorch, Demucs, Whisper, MusicGen) are bundled so everything runs fully offline.

Download for Windows Free · no credit card

The installer is unsigned, so Windows SmartScreen may warn on first run - choose "More info → Run anyway". macOS and Linux are not supported yet.

What You Need to Run It

Windows 10 / 11

64-bit Windows 10 or 11. macOS and Linux builds are not available yet.

NVIDIA GPU recommended

An NVIDIA GPU (CUDA) makes the AI models fast. No GPU? A CPU fallback still works, just slower.

~6 GB disk space

The app and bundled AI models take roughly 6 GB once installed.

8 GB+ RAM

8 GB of RAM is the comfortable minimum; 16 GB helps with longer tracks and stem separation.

Questions About PD2AM

Is PD2AM the same as PumpyDumpy2Visual?

No - they are two apps that work together. PumpyDumpy2Visual turns your music into a video; PumpyDumpy2AudioMaster masters, repairs, and packages the audio itself. One Pro subscription unlocks both.

Does my audio get uploaded anywhere?

No. All processing and AI inference happen on your own PC. Your tracks never leave your computer, which is why the AI models are bundled into the installer.

Why is the download so large?

PD2AM ships full AI models (PyTorch, CUDA, Demucs, Whisper, DeepFilterNet, MusicGen) so it runs completely offline. That makes the installer around 3 GB, but you never depend on a cloud service.

Can I use the results commercially?

Yes - mastered audio, stems, repaired vocals, and delivery packs are yours to release. The only exception is audio generated by the MusicGen model, which is non-commercial (CC-BY-NC). Loop-based extension is unrestricted.

What does Pro unlock?

Pro removes the audio watermark and grants a commercial-use license. The same Pro subscription also unlocks PumpyDumpy2Visual, so you get both apps for one price.

Do I need a powerful computer?

An NVIDIA GPU makes the AI features fast, but PD2AM falls back to your CPU when no GPU is available. Mastering and repair work fine on a normal machine; stem separation is the heaviest task.
