Name: Mirelo SFX1.6
Author: Mirelo

Sfx1.6 Inpaint Audio by Mirelo - advanced AI model for audio-to-audio. Delivers high-quality results with fast inference, suitable for both creative and production workflows.

Input

Audio Url(string)

URL of the source audio. Maximum 10 seconds — longer clips are rejected. The model regenerates only the region defined by `segment`; everything outside it is preserved.

Seed(integer)

Seed for generation. -1 or None for random. Minimum: -1.

Text Prompt(string)

Optional text prompt guiding the regenerated segment.

Upload Audio Format(string)

Audio format for the returned files. Allowed values: wav, mp3, aac, flac.

Segment(string)

Region [start_s, end_s] (in seconds, 1s ≤ start < end ≤ 10s, 1–8s span) to regenerate. The audio outside this region is preserved.

Num Samples(integer)

Number of variations to generate. Range: 1 to 4.

Input Schema

6 parameters · 0 required · 6 optional

Parameter	Type	Required	Description
`seed`	integer	Optional	Seed for generation. -1 or None for random. · Min: -1
`audio`	string	Optional	URL of the source audio. Maximum 10 seconds — longer clips are rejected. The model regenerates only the region defined by `segment`; everything outside it is preserved.
`segment`	string	Optional	Region [start_s, end_s] (in seconds, 1s ≤ start < end ≤ 10s, 1–8s span) to regenerate. The audio outside this region is preserved.
`num_samples`	integer	Optional	Number of variations to generate. · Min: 1 · Max: 4 · Default: 1
`text_prompt`	string	Optional	Optional text prompt guiding the regenerated segment.
`upload_audio_format`	string	Optional	Audio format for the returned files. · Options: wav, mp3, aac, flac · Default: "wav" wavmp3aacflac

Output Schema

Field	Type	Description
`id`	string	Unique identifier for the generation task
`status`	string	Task status: pending, running, completed, failed, timeout
`model`	string	Model used for the generation
`outputs`	array	Array of output items
`outputs[].url`	string	URL of the generated artifact
`outputs[].content_type`	string	MIME type (e.g. image/png, video/mp4)
`error`	object \| null	Error details if failed, null on success
`error.type`	string	Machine-readable error type code
`error.message`	string	Human-readable error description

Async Workflow

This model uses asynchronous execution. Submit a request and poll for the result.

Submit — POST to /v1/run, receive an id
Poll — GET /v1/run/{id} until status is completed, failed, or timeout
Retrieve — Read outputs from the completed response

API README

Sfx1.6 Inpaint Audio

Sfx1.6 Inpaint Audio is built for context-aware sound design, with this exact route focused on localized audio repair. Sfx1.6 Inpaint Audio by Mirelo - advanced AI model for audio-to-audio. Delivers high-quality results with fast inference, suitable for both creative and production workflows. It is designed for production workflows that need a clearly scoped media operation instead of a generic assistant response, preserving the supplied direction while returning an artifact ready for review, iteration, or downstream assembly.

The request surface keeps creative direction and delivery choices explicit through seed, segment, audio_url, sync_mode, num_samples, text_prompt. Teams can lock source material, describe the intended result, choose supported output controls, and rerun the same request structure across variations. This makes experiments easier to compare and larger pipelines easier to operate without hiding important decisions inside an opaque preset.

Highlights

Localized Audio Repair. The mirelo/sfx1.6/inpaint-audio route is dedicated to localized audio repair, keeping inputs and outputs matched to this operation.
Timing-Sensitive Effects. Within mirelo/sfx1.6/inpaint-audio, documented prompt and media controls direct timing-sensitive effects while keeping the brief close to the result.
Production-Ready Audio Output. The mirelo/sfx1.6/inpaint-audio result provides production-ready audio output in a machine-consumable form for review and downstream production.
Route-specific control. For mirelo/sfx1.6/inpaint-audio, documented controls include seed, segment, audio_url, sync_mode, num_samples, text_prompt, defining the supported variation space for this exact route.

Pricing

Per request	`$0.001250`

When to Use

Scenario	Why it fits
Choose this route	When the deliverable is specifically localized audio repair, not a neighboring generation or editing task.
Production iteration	When creative teams need repeatable timing-sensitive effects with an explicit request payload.
Automated pipelines	When production-ready audio output must flow into review, storage, compositing, or publishing.
Controlled variations	When a stable brief should be rerun while changing only documented inputs.
Prototype to scale	When the same `mirelo/sfx1.6/inpaint-audio` contract should serve a single experiment and a larger batch later.

Prompt Guide

Lead with the subject or source, then state the transformation, important spatial or temporal details, style, and finish. Supply only documented fields, keep media URLs reachable, and vary one control at a time when comparing outputs.
