Overview

Mirelo is a sound-effects generator for video creators who need audio shaped around picture, as well as developers building video-audio features into products or pipelines. Its combination of frame-timed generation, editing, and workflow integrations makes it more than a prompt-to-sound tool, though the free tier is constrained for ongoing projects.

Video analysis is the differentiator: Mirelo can generate effects timed to scenes and actions, then let users refine clips in the same browser workspace. That makes it a strong fit when sound work needs to follow picture; it is less compelling for someone seeking only a basic, standalone sound generator.

Key features

Video-aware effects: Mirelo SFX analyzes video and generates frame-timed sound effects. Text prompts can also create sounds that are off-screen or imaginative, so the tool is not limited to reproducing visible action.
Editing after generation: Users can extend clips, create seamless ambient loops, and inpaint glitches while preserving the rest of a take. These operations support refinement rather than forcing a full replacement when one section needs work.
Studio workspace: The browser-based Mirelo Studio combines video-to-sound, text-to-SFX, and iterative editing. It suits creators who want those steps in one workspace.
Workflow connections: Plugins for Adobe Premiere Pro, DaVinci Resolve, and Roblox Studio bring Mirelo into named creative tools. The developer REST API and OpenAPI specification support product or pipeline integrations; Mirelo MCP connects compatible clients such as Claude, Cursor, and ChatGPT for generating and editing effects.
Security and support: Mirelo AI GmbH says its information security management system is certified to ISO/IEC 27001:2022 through July 13, 2029. It says customer data is protected in transit with TLS and encrypted at rest, with production access following least privilege. Email support covers Studio, billing, and API issues, with responses within two business days.

Pricing

Mirelo uses monthly Stripe billing. After creating an account, users can upgrade, downgrade, or cancel in Studio. Commercial use is included, and the maximum clip length is 60 seconds.

Free is useful for evaluating generation, but a one-week retention period and watermarked exports make it a poor choice for keeping projects or delivering finished work. Creator is the entry paid tier for individual or smaller workloads, with a 20-project cap. Studio removes that cap and raises the monthly allowance; Scale and Business offer progressively larger credit pools and lower additional-credit rates for higher-volume use. Enterprise is the fit for custom volume needs or teams requiring dedicated support and API access.

Platforms

Mirelo supports web, macOS, and Windows, with API access for integration. The browser-based Studio provides the central workspace; plugins and MCP connections add routes into supported creative and AI-client workflows.

Who it's for

Mirelo is best suited to video editors, creators, and developers who value sound that follows the image and want controls to revise it afterward. The Premiere Pro, DaVinci Resolve, and Roblox Studio plugins may suit users working in those environments, while the API and MCP are relevant to product and pipeline builders. It is a weaker fit for projects that need clips longer than 60 seconds or for users who need persistent, unwatermarked exports on a free plan.

Pros and cons

Pro: Frame-timed generation ties effects to scenes and actions, addressing the synchronization work that prompt-only sound creation leaves to the editor.
Pro: Clip extension, ambient looping, and glitch inpainting allow targeted revision while preserving the rest of a take.
Pro: Plugins, a REST API, and MCP connections accommodate both creative applications and developer workflows.
Con: Free projects disappear after one week and exports have a watermark, limiting the tier to evaluation rather than durable production.
Con: The 60-second maximum clip length rules it out for workflows that require longer generated clips.
Con: Creator limits users to 20 projects; unlimited projects begin at the 99.00 EUR per month Studio tier.

Alternatives

For a broader starting point, browse AI Sound Effect Generators; Audio-to-MIDI converters are a separate category for readers whose goal is MIDI conversion rather than generated video sound.

Sonilo is worth comparing if a defined free allowance matters: its free plan gives 2,000 credits every two weeks, seven 15-second video soundtracks, six minutes of text-to-music, and eight minutes of text-to-sound-effects, with preview-quality exports.
HueFold is another freemium option, with Android and web support and a free starting tier.
Morphic may suit a single-user web workflow: its forever-free tier allows up to 20 credits for one user, with limited models and workflows.
Pixazo AI SFX Generator offers a seven-day trial with 100 bonus credits, but those credits lapse afterward and the trial excludes API access and commercial rights.
SeedAudio offers a first generation without sign-up, 20 credits on sign-up, and generations up to 60 seconds.
Async may appeal to users who want AI media chat alongside editing: its free tier includes 10 lifetime AI credits, one hour of media upload to AI chat, up to 720p export, and 2 GB of storage.
Creen is an option for Android, iOS, or web users; select models have free, unlimited daily generation, while premium models may use credits.
AI SFX Lab has a free web tier with 100 credits a month, generations up to five seconds, no downloads, and no commercial use.

Verdict

Choose Mirelo if video-aware sound generation, in-workspace editing, and integration with creative tools or developer pipelines are central to your workflow. Its strongest case is the move from synchronized generation to targeted refinement; look elsewhere if you need longer clips or expect the free tier to provide lasting, unwatermarked project exports.
