Pricing

A run with the default settings costs 1 credits. The exact cost updates in the playground as you change settings, and you're only charged when you press Run. Failed runs are refunded automatically.

Inputs

negative_prompttextareadefault: ""

Text description of qualities to avoid in the output.

durationnumberdefault: 30

Duration of the generated audio in seconds.

num_inference_stepsintegerdefault: 50

Number of sampling steps. Base (non-distilled) checkpoints typically need ~50 for good quality.

guidance_scalenumberdefault: 7

Classifier-free guidance scale. Higher values follow the prompt more strictly; ~7.0 is a good starting point for base checkpoints.

seedinteger

Random seed for reproducible outputs. Omit for a random seed.

enable_prompt_expansionbooleandefault: false

If True, the prompt will be expanded using an LLM for more detailed and higher quality results.

enable_safety_checkerbooleandefault: true

Enable NSFW content safety checking.

sync_modebooleandefault: false

If True, the audio is returned inline as a data URI and the result is not saved to the request history.

output_formatselectdefault: "mp3"

Container format for the generated audio output.

Options: mp3, wav, flac, ogg, opus, m4a, aac

bitratetextdefault: "192k"

Audio bitrate for compressed output formats (e.g., mp3, aac, opus). Format e.g. '192k' or '320k'. Ignored for lossless formats (wav, flac).

prompttextarearequired

Text description guiding how the source audio should be transformed.

audio_urlfilerequired

Source audio to transform.

init_noise_levelnumberdefault: 0.9

How much noise to add to the source audio. 1.0 fully replaces the audio with noise (pure generation); 0.1 keeps the source close to the input. 0.5 sits halfway between.
