The studio

One link. A full visual studio.

Everything happens on your machine — no uploads, no waiting rooms, no monthly fees.

One-link import

Paste a URL — or a full YouTube playlist. MyD Visual Audio downloads, separates, and saves each track as its own project. Batch-process an entire setlist while you grab coffee.

Six clean stems

Vocals, drums, bass, guitar, piano and other — separated by the state-of-the-art Demucs model, with two quality presets: Standard for speed and High for deeper isolation.

Color-coded multitrack deck

Per-stem faders, mute and solo, clickable waveforms, and a condensed view that packs every stem into a slim chip while keeping all controls accessible. Jump anywhere — every track and video follows instantly.

Real OS video windows

The video plays in a true, draggable desktop window — locked frame-by-frame to the audio clock. Add a second camera angle with its own start time and frame-perfect nudge. Or mute it and watch the visual-only layer.

Instrument monitors + full-screen layout

Open a live frequency spectrum for any stem — peak-hold trails, real-time response. Then click Display All to send every instrument full-screen onto a second monitor in a gap-free grid: 3 rows, 3 or 4 columns, 2×2, 5 columns, or 6 equal boxes. Click anywhere in a cell to cycle its visual style; double-click to repaint it in a new color.

BPM, key & chords — instantly

Every imported track gets its own music theory readout: tempo, key, and a chord strip that runs along the deck while the song plays — with a little piano diagram of each chord as it hits. Learn the voicing, steal the progression, impress your band. It's like having a music teacher sitting on your fader.

Library, export & shortcuts

Saved projects regrouped by playlist, with compact and large views. Export the whole thing as a folder or ZIP. And the whole studio responds to musical keys — V/G/B/D/P/O to mute a stem in a heartbeat, Shift to solo, M to mute all, S to clear solos. Space to play. That's it.

Stems that vanish

Near-silent stems are detected and dropped automatically, so the deck never shows dead weight. A sparse acoustic track arrives as the two or three real instruments that are actually there — not a wall of empty channels.

An interface that steps aside

Frameless, auto-hiding chrome — the toolbar fades away after a few seconds so nothing stands between you and the music. Hover to bring it back. The instruments, the video, the waveforms: that's the interface now.

One click to studio

From link to layout in three steps

1

Paste a link

Drop in any YouTube URL — singles or full playlists. The video downloads, named automatically from the real title. Or upload a video from your hard drive.

2

AI separates the audio

Demucs splits the soundtrack into six instrument stems (Standard or High quality) while you watch. The loading overlay shows each stem as it arrives, then fades to reveal the deck — and whispers the BPM, key and chords in the corner.

3

Play it visually

Stems land on a color-coded deck beside the video in its own OS window. Solo, mute, jump, study, export. Or hit Display All and send every instrument full-screen to a second monitor.

True multi-window

Your video is not an embed. It's a window.

MyD Visual Audio drives the video into real OS windows, synced to the same clock as the audio. The interface itself is a frameless, auto-hiding chrome — the video is what you see, not the app chrome.

01:42 / 04:18
CAM A — master
00:47 / 04:18
CAM B — aligned +0.0s

±10s jumps · one click and every track and window follows.

PER-VIDEO START TIME · set a delayed start for video 2 (e.g. 0:15). While it waits, the app shows a large watermark logo. When the master clock hits the mark, the video begins.

0.1s nudges · frame-perfect alignment while both videos play.

INSTRUMENT MONITORS · open a live spectrum per instrument with peak-hold trails. Click anywhere to cycle through 6 visual styles — bars, wave, radial, LED — and double-click to repaint the whole window in a new color.

Full-screen layout

Your stem monitors. Full-screen. On a second display.

Click the ▦ Display All button on the master video row — the app picks the best layout for your stem count and opens a gap-free, full-screen grid on your second monitor. Cycle through preset arrangements with every click.

3 horizontal rows

Full-width spectrums stacked — ideal for wide monitors. Stems fill the screen edge to edge.

4 vertical columns

Four slim columns, full-height. A great everyday arrangement for four or more stems.

3 vertical columns

Three equal columns side-by-side. Great for portrait monitors or narrow displays.

4 grid (2×2)

Four equal quadrants. Perfect for a balanced four-stem view of your mix.

5 vertical columns

Five slim columns, full-height. For projects with five instruments or more.

6 equal boxes (3×2)

Three columns, two rows — six equal boxes for every stem in your project.

Brand watermark

After the last layout, the screen shows a polished brand watermark. Next click closes the window. Clean.

Each cell draws a live colored spectrum. Click the cell's title to cycle its visual style — Bars, Mirror, Wave, Radial, LED, Center. Every stem, your choice.

Batch playback

Import an entire YouTube playlist in one click.

From "Load Playlist" in the menu to a library full of projects — the app downloads, separates, and saves every video in sequence, one by one, with a live progress window that shows each track's status, time estimate, and screenshot.

📋

Selection screen

After fetching the playlist, choose exactly the videos you want with checkboxes. Select all, deselect, start over — the UI shows every video with its thumbnail and duration.

Sequential build

Videos process one by one: download first (android client for reliability), then separate with Standard quality. Each step updates the live progress bar and ETA.

🛑

Cancel anytime

Click any queued row to cancel it before it starts — the row turns grey and is skipped. Perfect for when you don't want to wait for the last few tracks.

📊

Completion stats

When done, a summary shows every project's runtime, file size, and stem count — plus totals for everything. Projects are stored in the library grouped by playlist title.

During long builds the separation engine is capped at 80% CPU usage, so you can keep working or browse while the playlist processes.
