# Audio nodes

> Every audio node in Nodaro, from text to speech, voice changing and dubbing to Suno music, sound effects, stem separation, editing, sync and transcription.

Source: https://nodaro.ai/docs/nodes/audio

The **Audio** tab of the node picker holds every node that makes, changes, cleans, edits or reads sound. It covers speech and voiceover, voice changing and dubbing, music, sound effects, stem separation, audio editing, recording sync and transcription. Press Tab on the canvas and open the **Audio** tab to see the nodes, grouped in nine families.

## The nine families

### Add Your Own

Bring your own sound into a workflow. [Upload Audio](https://nodaro.ai/docs/nodes/audio/upload-audio) takes a file or a direct link and lets you trim it before upload. [Reference Audio](https://nodaro.ai/docs/nodes/audio/reference-audio) also extracts the sound track of a YouTube video.

### Speech & Voiceover

Turn text into speech with ElevenLabs voices. [Text to Speech](https://nodaro.ai/docs/nodes/audio/text-to-speech) reads a text with one voice, in up to 46 languages, with audio tags for emotion. [Text to Dialogue](https://nodaro.ai/docs/nodes/audio/text-to-dialogue) voices a whole conversation, with a voice for each line, in one file.

### Voices

Change, create and translate voices. [Voice Changer](https://nodaro.ai/docs/nodes/audio/voice-changer) gives a recording or a talking video a new voice, and [Voice Changer Pro](https://nodaro.ai/docs/nodes/audio/voice-changer-pro) gives each speaker in a conversation a voice of their own. [Voice Design](https://nodaro.ai/docs/nodes/audio/voice-design) and [Voice Remix](https://nodaro.ai/docs/nodes/audio/voice-remix) create a new voice from a description, and [Dubbing](https://nodaro.ai/docs/nodes/audio/dubbing) translates speech or a whole video into another language.

### Music

Make and edit songs. [Suno Create Music](https://nodaro.ai/docs/nodes/audio/suno-create-music) makes a full song from a prompt or your own lyrics, and [Generate Music](https://nodaro.ai/docs/nodes/audio/generate-music) makes a track from a reference song plus a prompt. The other Suno nodes write lyrics, make covers and mashups, extend a track, replace a section, add vocals or an instrumental, and convert a song to WAV.

### Sound Effects

Generate sound from a description. [Text to Audio](https://nodaro.ai/docs/nodes/audio/text-to-audio) makes sound effects and ambience up to 22 seconds long, including loops that repeat without a gap.

### Clean & Separate

Take sound apart. [Voice Extractor](https://nodaro.ai/docs/nodes/audio/voice-extractor) keeps only the voice and removes noise and music. [Audio Separation](https://nodaro.ai/docs/nodes/audio/audio-separation) splits any song into vocals and instrumental or into stems, and [Suno Separate](https://nodaro.ai/docs/nodes/audio/suno-separate) does the same for songs made with Suno.

### Analyze

Measure a recording without changing it. [Silence Detect](https://nodaro.ai/docs/nodes/audio/silence-detect) finds the silent spans to cut, and [Audio Sync](https://nodaro.ai/docs/nodes/audio/audio-sync) measures how far apart several recordings of one conversation are. Both run locally, with no AI model and no provider key.

### Edit Audio

Cut, join, layer and shape sound. [Trim Audio](https://nodaro.ai/docs/nodes/audio/trim-audio) cuts a section, [Combine Audio](https://nodaro.ai/docs/nodes/audio/combine-audio) joins clips end to end, and [Mix Audio](https://nodaro.ai/docs/nodes/audio/mix-audio) layers tracks with a volume for each. [Adjust Volume](https://nodaro.ai/docs/nodes/audio/adjust-volume) changes the level and adds fades, and [Audio FX](https://nodaro.ai/docs/nodes/audio/audio-fx) adds reverb, telephone, megaphone and echo effects.

### Transcribe

Turn speech into text and timings. [Transcribe](https://nodaro.ai/docs/nodes/audio/transcribe) writes down what was said, with word timings for captions, speaker labels and audio events. [Forced Alignment](https://nodaro.ai/docs/nodes/audio/forced-alignment) times each word of a script you already have.
