ExactMusic

Exact-duration AI music for voiceovers.

Generate instrumental BGM from 5 to 120 seconds. Type a prompt, hit Generate, download an MP3 that matches your cut.

Built for the cut, not a loop

ExactMusic is an English-first tool for instrumental and voiceover BGM that ends on the second you asked for.

Exact duration

Pick any length from 5 to 120 seconds. Lyria output is trimmed or loop-padded with ffmpeg so the file matches your timeline.

Instrumental BGM

Pure music for voiceover, ads, and short video — no lyrics competing with your narration.

Prompt to track

Describe mood, genre, and instruments. Generate, preview in the browser, then download the MP3.

Play and download

Every result has an audio player and a one-click download. Guests get one short preview; real Lyria audio when a key is set.

Credits, not subscriptions

Signup grant plus pay-as-you-go packs. Suggested cost: 1 credit ≤30s, 2 ≤60s, 3 ≤120s.

Stripe checkout

Credit packs via Stripe. Alipay and WeChat stay in the engine but are hidden from the public pricing UI.

Credit packs
