What it is¶

Sonilo is an API-first audio tool for editors, creative-product teams, and developers who need music or sound tied to a cut.

• generates music from text or video;
• generates text- and video-led sound effects;
• mixes supplied voice and music with automatic ducking.

Development line¶

• 2026-06-29 — Sonilo v1.1 linked to a text-to-music endpoint. It delivers tighter video-to-music alignment, preserves original speech, and adds per-segment prompts. The first-party release itself is dated 2026-06-18.

What changed¶

2026-06-29 — Sonilo v1.1 delivers tighter video-to-music alignment, preserves original speech, and adds per-segment prompts. The first-party release itself is dated 2026-06-18.

How to use this¶

From 2026-06-29, we treat Sonilo v1.1 as a distinct candidate endpoint to evaluate through the linked text-to-music route and Sonilo platform, without assuming capabilities or migration requirements until the source pages are researched.

1. Create an API key, keep it server-side, and add the required API balance before attempting generation. — https://platform.sonilo.com/docs/quickstart
2. Preflight the account’s enabled services and usage, then select text-to-music for a musical brief or video-to-music for a locked visual timeline. — https://platform.sonilo.com/docs/api
3. For direct text generation, POST a prompt and a 5–360 second duration to /v1/text-to-music. — https://platform.sonilo.com/docs/text-to-music
4. Consume streamed audio chunks only through the complete event, or use async mode and poll the returned task ID to a terminal state. — https://platform.sonilo.com/docs/text-to-music
5. If the product already uses fal, call the v1.1 text model at sonilo/v1.1/text-to-music rather than building a separate provider integration. — https://fal.ai/models/sonilo/v1.1/text-to-music

Best practices¶

• Keep API keys in a server-side environment variable. Revoke and replace an exposed key rather than embedding it in a client app. — https://platform.sonilo.com/docs
• Treat 401, 402, 403, and 429 as distinct setup, balance, service-access, and backoff conditions. Do not create placeholder audio after a failed request. — https://platform.sonilo.com/docs/text-to-music
• Use video input when timing, cuts, or voice space must guide the soundtrack. Use text input when the task is a standalone cue. — https://platform.sonilo.com/docs/api
• For paid or client work, review the generated track against voice-over and scene changes, retain the output and account record, and confirm that the current plan covers the intended release. — https://sonilo.com/blog/ai-music-video-creators-2026

Superseded by this¶

• 2026-06-18 — For video scoring that requires preserved dialogue or scene-specific direction, v1.1 supersedes v1.0-style generation without those controls. The release does not state that v1.0 endpoints were retired.
• 2026-08-03 — Where a project already has separate voice and music assets, the documented audio-ducking endpoint supersedes manual volume riding when its two-input workflow fits.

Still unknown¶

• The supplied event is dated 2026-06-29, while Sonilo’s release page dates v1.1 to 2026-06-18; no primary source found explains the eleven-day difference.
• The v1.1 comparison figures are vendor-reported and no public evaluation protocol or independent replication was found.
• The direct Sonilo text endpoint documents a 360-second ceiling, while the fal v1.1 text endpoint documents 600 seconds; treat limits as route-specific until confirmed for the intended account.
• No public primary source found in this pass declares a successor model after v1.1.
