AI Backing Track Generator

Add Instrumental to Your Vocals

Turn an a cappella, voice memo, or rough vocal recording into a full produced song. AI generates a backing track that matches your key and tempo, then mixes it under your voice.

Give any vocal a full production

Drop your vocal recording in, choose a genre, and Vocuno builds the song around your voice — automatic key and tempo matching included.

Auto Key and Tempo Match

Vocuno analyzes your vocal and locks the new instrumental to the same key and BPM so the backing sits perfectly under the voice.

Pick a Genre or Vibe

Lo-fi, pop, hip-hop, R&B, rock, EDM, country, K-pop, gospel, anime opening — pick the vibe and the AI shapes the arrangement to match.

Powered by Suno and Vocuno

Generate instrumentals through Suno and Vocuno's own engine, then preview, A/B, and pick the take that lifts the vocal best.

Works on Voice Memos and A Cappellas

Designed for raw vocal takes — voice memos, demo recordings, a cappellas, or stems pulled from stem separation. No pre-mixed track required.

Style Prompts for Direction

Add an optional style prompt to steer the instrumental — "slow piano ballad", "drill beat with 808s", "dreamy synthwave" — and the generator follows the brief.

Pairs with Mixing and Mastering

Once the instrumental is added, run the result through Vocuno's mixing and mastering tools for a clean, release-ready song.
