mirelo/sfx1.6/text-to-audio

Name: Mirelo SFX1.6
Author: Mirelo

Sfx1.6 by Mirelo - generate music, sound effects, and audio from text descriptions with AI. Create original compositions, ambient sounds, and audio content for any creative project.

Input

Duration(integer)

0.160

Duration of the generated audio in seconds. Range: 0.1 to 60.

Seed(integer)

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

Upload Audio Format(string)

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

Ambience(boolean)

When true, generate a seamlessly loopable ambience tile (room tone, rain, drones, etc.). When false, generate a generic text-conditioned SFX of `duration` seconds.

Double Output(boolean)

Only used when ambience=true: concatenate the loop with itself for a 2x-length output.

Num Samples(integer)

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

Text Prompt(string)

Text prompt for the generated audio.

Idle

Example output — click Run to generate your own

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)

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 Text To Audio

Sfx1.6 Text To Audio is built for context-aware sound design, with this exact route focused on prompt-driven sound-effect creation. Sfx1.6 by Mirelo - generate music, sound effects, and audio from text descriptions with AI. Create original compositions, ambient sounds, and audio content for any creative project. 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, ambience, duration, 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

Prompt-Driven Sound-Effect Creation. The mirelo/sfx1.6/text-to-audio route is dedicated to prompt-driven sound-effect creation, keeping inputs and outputs matched to this operation.
Timing-Sensitive Effects. Within mirelo/sfx1.6/text-to-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/text-to-audio result provides production-ready audio output in a machine-consumable form for review and downstream production.
Route-specific control. For mirelo/sfx1.6/text-to-audio, documented controls include seed, ambience, duration, sync_mode, num_samples, text_prompt, defining the supported variation space for this exact route.

When to Use

Scenario	Why it fits
Choose this route	When the deliverable is specifically prompt-driven sound-effect creation, 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/text-to-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.
