sakemin /musicgen-remixer:cdba0e0d

Playground API

Input

model_version

string

Model type. Computations take longer when using `large` or `stereo` models.

Default: "stereo-chord"

prompt

string

Shift + Return to add a new line

A description of the music you want to generate.

music_input

file

An audio file input for the remix.

multi_band_diffusion

boolean

If `True`, the EnCodec tokens will be decoded with MultiBand Diffusion. Not compatible with `stereo` models.

Default: false

normalization_strategy

string

Strategy for normalizing audio.

Default: "loudness"

beat_sync_threshold

number

When beat syncing, if the gap between generated downbeat timing and input audio downbeat timing is larger than `beat_sync_threshold`, consider the beats are not corresponding. If `None` or `-1`, `1.1/(bpm/60)` will be used as the value. 0.75 is a good value to set.

large_chord_voca

boolean

If `True`, more chords like 7th, diminished and etc are used. If `False` only 12 major and 12 minor chords are used.

Default: true

chroma_coefficient

number

(minimum: 0.5, maximum: 2)

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.
