Fadr
AI-powered stem separation, remixing, and beat creation for DJs and producers
Fadr is a browser-based AI music platform that separates any song into its individual components — vocals, drums, bass, and instruments — using deep learning stem separation. DJs and producers use these isolated stems to create remixes, mashups, and new beats without needing professional DAW software or audio engineering skills. With built-in key and tempo detection, a remix editor, and a beat generator, Fadr makes advanced music deconstruction and reconstruction accessible directly in your web browser.
Visit FadrWhat is Fadr?
Fadr is a browser-based AI music platform founded in 2020 that specializes in stem separation and music remixing. Stem separation is the process of using AI to isolate the individual audio layers within a mixed recording — typically the vocal track, drum kit, bass line, and melodic instruments — into separate audio files. These separated components, called stems, can then be manipulated independently, allowing DJs and producers to create remixes, mashups, and new arrangements that would otherwise require access to the original multitrack session files.
What sets Fadr apart from command-line tools like Spleeter (an open-source stem separator from Deezer) is its accessible browser-based interface and integrated production tools. After separation, you can work with your stems directly in the Fadr editor: adjust volumes, apply pitch shifting, change tempo, and layer stems from different tracks to create mashups. The key and tempo detection feature analyzes each uploaded track and suggests compatible combinations, making it easier to create mashups that sound musically coherent rather than off-key.
For DJs, Fadr provides a practical toolkit for creating exclusive edits and remixes that can be used in live sets. Isolating the vocal from a popular track to layer over a different instrumental, or extracting the drums from one song to blend with the melody of another, are common creative workflows that Fadr supports with a visual, browser-based interface that does not require downloading or configuring software.
The platform also includes a beat generator that creates original drum patterns and loops, and an acapella library for users who want pre-cleared vocal stems to work with. Because Fadr runs entirely in the browser, it works on Windows, macOS, and any device with a modern web browser and an internet connection — removing the barrier of DAW ownership and technical audio knowledge that traditionally limited music production to professionals.
Key Features
AI Stem Separation
Separates any audio track into vocals, drums, bass, and instruments using deep learning. Upload an MP3 or WAV and receive four isolated stem tracks for production use.
Key & Tempo Detection
Automatically detects the musical key and BPM of uploaded tracks. Helps DJs identify compatible tracks for mashups and pitch-matched mixing without manual analysis.
Mashup Creator
Combine stems from multiple tracks in the browser-based editor to create mashups. Layer vocals from one song over the instrumentals of another with visual timeline editing.
Beat Generator
Create original drum patterns and rhythmic loops with the AI beat generator. Adjust groove, density, and feel to produce custom beats that complement your remix stems.
Remix Tools
Pitch shift, time stretch, reverse, and loop individual stems within the browser editor. Apply effects and adjust stem volumes to craft finished remixes ready for export.

Frequently Asked Questions
What is Fadr?
Fadr is a browser-based AI music remixing and stem separation platform built for DJs, producers, and music enthusiasts. It uses deep learning to separate any audio track into vocals, drums, bass, and instruments — called stems — which can then be used to create remixes and mashups directly in the browser. No software installation is required, and it works on any device with a modern web browser.
Is Fadr free?
Fadr has a free plan with limited stem separations and basic export quality. For regular DJ and production use, the Basic plan at $9.99/month provides 50 stem separations with full WAV quality exports. The Pro plan at $19.99/month unlocks unlimited separations, and the Studio plan at $49.99/month adds a commercial license for producers working on professional projects. Annual billing reduces the per-month cost on all paid plans.
How accurate is Fadr's stem separation?
Fadr's stem separation produces strong results for well-produced pop, hip-hop, and electronic music where the frequency ranges of different elements are clearly defined. Professionally mixed tracks with good headroom typically yield clean, usable stems with minimal bleed between layers. Results are less clean with heavily compressed radio masters, live recordings with natural room bleed, or genres where instruments share similar frequency ranges. For DJ remixing purposes, the quality is generally sufficient for professional use.
How do I create a mashup with Fadr?
Upload two or more tracks you want to combine, then run stem separation on each. Fadr will produce separate vocal, drum, bass, and instrument files for each track. In the Fadr browser editor, drag the vocal stems from one track and the instrumental stems from another onto the timeline. Use the key and tempo detection results to pitch-match and time-align the elements so they sound cohesive. Adjust volumes, apply pitch shifting if needed, then export your finished mashup as a WAV file.
What audio formats does Fadr support?
Fadr accepts MP3 and WAV files as input for stem separation. Exported stems and finished remixes can be downloaded as WAV files for full audio quality. MP3 export is also available for smaller file sizes. The platform processes files in the cloud, so file size and length may affect processing time — longer tracks or high-bitrate files take more time to separate than shorter or compressed files.
Can I use Fadr for commercial music production?
Fadr's Studio plan at $49.99/month includes a commercial license that covers the platform's AI processing and tools. However, the underlying copyright of any source audio you separate belongs to the original artists and rights holders. Using separated stems from copyrighted music in commercial releases requires you to obtain a remix license from those rights holders separately. Fadr is safest for commercial use when applied to original recordings you own the rights to, royalty-free tracks, or music with a Creative Commons remix license.
