charlesmccarthy /musicgen:d5103269

Playground API

Input

model_version

string

Model to use for generation

Default: "stereo-melody-large"

prompt

string

Shift + Return to add a new line

A description of the music you want to generate.

input_audio

file

An audio file that will influence the generated music. If `continuation` is `True`, the generated music will be a continuation of the audio file. Otherwise, the generated music will mimic the audio file's melody.

duration

integer

Duration of the generated audio in seconds.

Default: 8

continuation

boolean

If `True`, generated music will continue from `input_audio`. Otherwise, generated music will mimic `input_audio`'s melody.

Default: false

continuation_start

integer

(minimum: 0)

Start time of the audio file to use for continuation.

Default: 0

continuation_end

integer

(minimum: 0)

End time of the audio file to use for continuation. If -1 or None, will default to the end of the audio clip.

multi_band_diffusion

boolean

If `True`, the EnCodec tokens will be decoded with MultiBand Diffusion. Only works with non-stereo models.

Default: false

normalization_strategy

string

Strategy for normalizing audio.

Default: "loudness"

top_k

integer

Reduces sampling to the k most likely tokens.

Default: 250

top_p

number

Reduces sampling to tokens with cumulative probability of p. When set to `0` (default), top_k sampling is used.

Default: 0

temperature

number

Controls the 'conservativeness' of the sampling process. Higher temperature means more diversity.

Default: 1

classifier_free_guidance

integer

Increases the influence of inputs on the output. Higher values produce lower-varience outputs that adhere more closely to inputs.

Default: 3

output_format

string

Output format for generated audio.

Default: "wav"

seed

integer

Seed for random number generator. If None or -1, a random seed will be used.
