What is the Stem Separator and how does it work?

The Stem Separator uses the HTDemucs deep learning model to split any song into individual stems — vocals, drums, bass, and other instruments. You can choose 4-stem or 6-stem mode (which adds guitar and piano). The AI model runs entirely in your browser using WebGPU or WebAssembly, so your audio never leaves your device. The model downloads once (~114–172MB) and is cached for future use.

Do I own the music I create on SongUp AI?

Yes. Every piece of content you create on SongUp AI comes with a full commercial license at no extra cost. You can use your creations on YouTube, Spotify, TikTok, in advertisements, films, games, or sell them. No royalty payments or attribution required.

What are client-side tools and why might they be slow?

Client-side tools (like Stem Separator, AI Blend, Neural Synth, Neural Auto-Tune, and Live Karaoke) run AI models directly in your browser instead of on cloud servers. This means your files never leave your device for maximum privacy. However, processing speed depends on your device's CPU and GPU. These tools work best on modern laptops and desktops with dedicated GPUs. They can be significantly slower on mobile devices.

Can I use SongUp AI on my phone?

Yes, SongUp AI works on mobile browsers. However, client-side AI tools (Stem Separator, AI Blend, Neural Synth, etc.) that process audio on your device can be very slow on phones due to limited processing power. Cloud-based tools (song generation, Hum to Song, AI mastering) work at full speed on mobile. For the best experience with client-side tools, use a laptop or desktop.

What audio formats does SongUp AI support?

SongUp AI supports MP3, WAV, M4A, FLAC, and OGG for input. Generated audio is typically delivered in MP3 format, while tools like the Stem Separator and Audio Editor export in high-quality WAV format. Images are exported as PNG, and videos as MP4.

How is SongUp AI different from other AI music generators?

SongUp AI combines AI music generation with a full suite of professional audio tools in one platform. Unlike basic AI music generators, SongUp AI offers stem separation, AI mastering, karaoke making, chord recognition, audio-to-MIDI conversion, a real-time DJ console, an audio editor, neural synthesizers, and more — all accessible from a web browser with no installations. Many tools run client-side for privacy, and all generated content includes commercial licensing.
