Create speech, music or sound with Audio Generator
Audio Generator is the Nodespell Creative Tool that brings every audio-making model into one place. It lists speech, music and sound-effect models together, so you can make a voiceover, a song or a sound effect from a prompt without first deciding which focused tool to open. The model you pick decides what kind of audio you get.
Audio Generator or a focused audio tool?
Section titled “Audio Generator or a focused audio tool?”Audio Generator is the umbrella. The three focused tools each show only one kind of model, which makes the picker shorter.
| You want… | Use |
|---|---|
| To browse all audio models, or you are not sure which kind you need | Audio Generator |
| Spoken words from a script | Voice Generator |
| A song, score or instrumental | Music Generator |
| A sound effect or ambience | Sound Effects Generator |
| A face that speaks | Speak (makes video, not audio) |
The same model gives the same result in Audio Generator and in its focused tool. Only the list of models differs.

What changes with the model?
Section titled “What changes with the model?”Because Audio Generator mixes three kinds of model, the form changes more than in any other tool when you switch.
- Speech models show a text field and voice settings, such as Voice, Speed and Stability on ElevenLabs TTS V3.
- Music models show a description prompt, and some add lyrics, an instrumental switch, or images for inspiration.
- Sound-effect models show a description and, on some models, a duration or loop option.
- Output format varies: some models let you choose MP3, WAV or other formats, others return one fixed format.
The focused tool pages describe each kind in detail: Voice Generator, Music Generator and Sound Effects Generator.
Where does the audio go?
Section titled “Where does the audio go?”Generate places the model node in the current graph level and runs it. Finished audio appears in Results in the Create form, where you can play it and step through older and newer results; the node keeps the full history, described in Takes. Generated audio also appears under Generated and Audio in the Asset Manager. To place it under a picture, use the Timeline.
Common problems
Section titled “Common problems”- The result is speech when you wanted music. The default model is a speech model. Choose a music model in the picker, or open Music Generator.
- “This value is required.” The model’s prompt or text field is empty.
- The prompt field says “Prompt controlled by an input node”. A connected node supplies the text. Edit that node or select Disconnect.
