Playground API

Input

prompt

string

Shift + Return to add a new line

A description of the music you want to generate.

text_chords

string

Shift + Return to add a new line

A text based chord progression condition. Single uppercase alphabet character(eg. `C`) is considered as a major chord. Chord attributes like(`maj`, `min`, `dim`, `aug`, `min6`, `maj6`, `min7`, `minmaj7`, `maj7`, `7`, `dim7`, `hdim7`, `sus2` and `sus4`) can be added to the root alphabet character after `:`.(eg. `A:min7`) Each chord token splitted by `SPACE` is allocated to a single bar. If more than one chord must be allocated to a single bar, cluster the chords adding with `,` without any `SPACE`.(eg. `C,C:7 G, E:min A:min`) You must choose either only one of `audio_chords` below or `text_chords`.

bpm

number

BPM condition for the generated output. `text_chords` will be processed based on this value. This will be appended at the end of `prompt`.

time_sig

string

Shift + Return to add a new line

Time signature value for the generate output. `text_chords` will be processed based on this value. This will be appended at the end of `prompt`.

audio_chords

file

An audio file that will condition the chord progression. You must choose only one among `audio_chords` or `text_chords` above.

audio_start

integer

(minimum: 0)

Start time of the audio file to use for chord conditioning.

Default: 0

audio_end

integer

(minimum: 0)

End time of the audio file to use for chord conditioning. If None, will default to the end of the audio clip.

duration

integer

Duration of the generated audio in seconds.

Default: 8

continuation

boolean

If `True`, generated music will continue from `audio_chords`. If chord conditioning, this is only possible when the chord condition is given with `text_chords`. If `False`, generated music will mimic `audio_chords`'s chord.

Default: false

multi_band_diffusion

boolean

If `True`, the EnCodec tokens will be decoded with MultiBand Diffusion.

Default: false

normalization_strategy

string

Strategy for normalizing audio.

Default: "loudness"

chroma_coefficient

number

(minimum: 0.5, maximum: 2.5)

Coefficient value multiplied to multi-hot chord chroma.

Default: 1

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.
