Fadr

What is Fadr?

Fadr is a free AI-powered audio processing tool made by Pebble that separates songs into individual instrument stems and enables music remixing without production experience. The platform uses machine learning to isolate vocals, drums, melodies, bass, and other instrumental elements from any audio file, allowing musicians, DJs, producers, and content creators to manipulate songs at the source level.

The free tier (Fadr Basic) provides unlimited stem separation with MP3 downloads, MIDI detection, and access to the Remix Maker tool for creating DJ sets and remixes. Users can extract four core stems: vocals, drums, melodies, and bass. The paid tier (Fadr Plus, $10/month or $100/year) unlocks advanced separation into 16+ individual stems including lead vocals, background vocals, kick, snare, piano, electric guitar, acoustic guitar, strings, and wind instruments. Fadr Plus also includes WAV lossless downloads, a Stems Plugin for DAW integration, API access, unlimited storage, and concurrent processing. The platform's upload limit is one hour per session on the free plan. Fadr additionally offers two companion tools: Siren, which generates playable instruments from text prompts, and DrumGPT, which creates customizable drum kits through natural language input. Both plugins integrate directly into digital audio workstations.

The service attracts bedroom producers, remixers, sample creators, podcast editors, and music educators who need quick stem extraction without manual production work. Fadr processes files in the browser and cloud, supporting common audio formats. The platform has expanded beyond stem splitting into creative music generation, positioning itself at the intersection of audio analysis and generative AI. Similar competing tools include iZotope RX for audio restoration, LANDR for mastering and stem separation, and Splitter.ai for vocal isolation, though Fadr's free tier and integrated remix workflow differentiate its positioning.
