Is MixSongs really free?

Mixing, editing, and crossfading are free—no account needed, no watermarks, and exports up to 192 kbps MP3. Lossless WAV/FLAC and 320 kbps MP3 exports require any $3 plan, which also includes 10 AI stem separations valid for 7 days.

Are my songs uploaded to a server?

No uploads occur during mixing or exporting—decoding, playback, and rendering all happen in your browser. Audio is only uploaded when using AI stem separation, and separated tracks are automatically deleted from the server after 30 days.

Which file formats are supported?

You can import MP3, WAV, FLAC, M4A/AAC, OGG/Opus, WebM audio, and AIFF. Free exports are 128 or 192 kbps MP3. Pro exports support 16-bit/24-bit/32-bit float WAV, 16-bit/24-bit FLAC, and 256 or 320 kbps MP3.

How good is the AI stem separation?

It uses two AI models for vocals and instruments, separating every moment of the song 4 times and blending the results into 6 lossless 24-bit FLAC stems. Your first song is free to try.

Will it run on my computer?

It runs in the latest versions of Chrome, Edge, Firefox, and Safari on Windows, macOS, Linux, and ChromeOS. A desktop or laptop is recommended for detailed editing.

How much does AI stem separation cost?

The first song is free. After that, 10 separations cost $3 (valid for 7 days), or 20 per month for $6. Both include Pro export access.

Can I mix songs I don't own?

Overview

MixSongs is a browser-based online audio mixing and editing tool that works on Windows, macOS, Linux, and ChromeOS. It offers a multi-track timeline where you can crossfade, cut, trim, and move clips—rather than simply joining audio files end to end. **Core Capabilities** - **Multi-track Mixing**: Import MP3, WAV, FLAC, M4A, OGG, AIFF, and more. Customize crossfade curves with volume control points, with support for snap-to-beat/bar, looping, undo, and redo. - **AI Stem Separation**: Uses two AI models to split a song into 6 stems: vocals, drums, bass, guitar, piano, and instrumental. Each stem has independent volume and fader controls. - **Tempo & Pitch Adjustment**: Tempo and pitch adjust independently—tempo changes preserve key, pitch changes preserve duration—and both support curve automation over time. Shift up to 24 semitones; tempo range from 0.25× to 4×. - **Natural Vocal Pitch Shifting**: Preserves the singer's timbre (formants) when transposing isolated vocals, while accompaniment can be shifted separately. - **Privacy & Local Processing**: Powered by a 32-bit float engine, decoding, playback, and rendering all happen locally in your browser. No audio files are uploaded during mixing or exporting. Projects auto-save in the browser. **Export Options** Free exports support 128 or 192 kbps MP3. Paid plans unlock Pro exports, including up to 24-bit WAV and FLAC, 320 kbps MP3, and sample rates up to 96 kHz, with built-in clipping protection and dithering. **Who It's For** Ideal for anyone who needs to quickly mix songs, create DJ mashups, extract karaoke instrumentals, or edit audio in the browser—no plugins or software installation required.
