Input Parameters
pitch Type: integerDefault: 0Range: -24 - 24
Semitone pitch shift for the converted vocals. Positive values raise pitch, negative values lower it.
dry_level Type: numberDefault: 0.8Range: 0 - 1
Dry level of the reverb effect on converted vocals (0–1).
f0_method Default: rmvpe
Pitch extraction method used during vocal conversion.
inst_gain Type: integerDefault: 0Range: -20 - 20
Volume gain (dB) for the instrumental track.
main_gain Type: integerDefault: 0Range: -20 - 20
Volume gain (dB) for the converted vocal track.
room_size Type: numberDefault: 0.15Range: 0 - 1
Room size of the reverb effect on converted vocals (0–1).
rvc_model (required) Type: string
Zip archive containing your RVC voice model. Must include a .pth file and optionally a .index file.
wet_level Type: numberDefault: 0.2Range: 0 - 1
Wet level of the reverb effect on converted vocals (0–1).
index_rate Type: numberDefault: 0.3Range: 0 - 1
Influence of the .index file on vocal conversion (0–1). Higher values make output closer to the voice model.
song_input (required) Type: string
Audio file to convert. Upload a file directly or provide a URL (e.g. https://example.com/song.mp3). Supported formats: mp3, wav, flac, ogg, m4a, aac.
backup_gain Type: integerDefault: 0Range: -20 - 20
Volume gain (dB) for the backup vocals track.
clean_vocals Type: booleanDefault: false
Apply noise reduction to the converted vocals.
protect_rate Type: numberDefault: 0.33Range: 0 - 0.5
Protection strength for consonants and breathing sounds (0–0.5). Lower values protect more.
rms_mix_rate Type: numberDefault: 1Range: 0 - 1
Blending rate of the volume envelope of the converted vocals with the original (0–1).
split_vocals Type: booleanDefault: false
Split audio into segments before vocal conversion.
output_format Default: mp3
Format of the output audio file.
autotune_vocals Type: booleanDefault: false
Apply autotune to the converted vocals.
