The TextEncodeAceStepAudio1.5 node prepares text and audio-related metadata for use with the AceStepAudio 1.5 model. It takes descriptive tags, lyrics, and musical parameters, then uses a CLIP model to convert them into a conditioning format suitable for audio generation.

Inputs

Parameter	Data Type	Required	Range	Description
clip	CLIP	Yes	N/A	The CLIP model used to tokenize and encode the input text.
tags	STRING	Yes	N/A	Descriptive tags for the audio, such as genre, mood, or instruments. Supports multiline input and dynamic prompts.
lyrics	STRING	Yes	N/A	The lyrics for the audio track. Supports multiline input and dynamic prompts.
seed	INT	No	0 to 18446744073709551615	A random seed value for reproducible generation. Has a control_after_generate widget. Default: 0.
bpm	INT	No	10 to 300	The beats per minute (BPM) for the generated audio. Default: 120.
duration	FLOAT	No	0.0 to 2000.0	The desired duration of the audio in seconds. Default: 120.0.
timesignature	COMBO	No	"2" "3" "4" "6"	The musical time signature.
language	COMBO	No	"en" "ja" "zh" "es" "de" "fr" "pt" "ru" "it" "nl" "pl" "tr" "vi" "cs" "fa" "id" "ko" "uk" "hu" "ar" "sv" "ro" "el"	The language of the input text.
keyscale	COMBO	No	"C major" "C minor" "C# major" "C# minor" "Db major" "Db minor" "D major" "D minor" "D# major" "D# minor" "Eb major" "Eb minor" "E major" "E minor" "F major" "F minor" "F# major" "F# minor" "Gb major" "Gb minor" "G major" "G minor" "G# major" "G# minor" "Ab major" "Ab minor" "A major" "A minor" "A# major" "A# minor" "Bb major" "Bb minor" "B major" "B minor"	The musical key and scale (major or minor).
generate_audio_codes	BOOLEAN	No	N/A	Enable the LLM that generates audio codes. This can be slow but will increase the quality of the generated audio. Turn this off if you are giving the model an audio reference. Default: True.
cfg_scale	FLOAT	No	0.0 to 100.0	The classifier-free guidance scale. Higher values make the output more closely follow the prompt. Default: 2.0.
temperature	FLOAT	No	0.0 to 2.0	A sampling temperature. Lower values make the output more deterministic. Default: 0.85.
top_p	FLOAT	No	0.0 to 2000.0	The nucleus sampling probability (top-p). Default: 0.9.
top_k	INT	No	0 to 100	The number of highest probability tokens to consider (top-k). Default: 0.

Outputs

Output Name	Data Type	Description
CONDITIONING	CONDITIONING	The conditioning data, which contains the encoded text and audio parameters for the AceStepAudio 1.5 model.
