Extract Audio from Video
The Extract Audio from Video block takes a video file and pulls out its audio track, saving the result as an MP3 file.
Extract MP3 audio from a video file
The Extract Audio from Video block takes a video file and pulls out its audio track, saving the result as an MP3 file. It accepts a video URL as its primary input and writes the output audio URL to a variable you specify, making the extracted audio available for use in subsequent steps of your workflow.
The block has two configuration fields: a video URL pointing to the source video file, and a destination variable name where the resulting audio URL will be stored. Once the block runs, downstream blocks can reference that variable to access the MP3.
This block fits into workflows that need to process or analyze audio separately from video — for example, pipelines that transcribe speech, run audio analysis, or repackage media content. It acts as a conversion step between a video source and any audio-focused blocks that follow it.
What you can build
Real-world workflows powered by the Extract Audio from Video block.
Transcribe Video Speech
Extract the audio track from a recorded video and pass the resulting MP3 to a speech-to-text block to generate a transcript.
Podcast Clip Extraction
Pull audio from video recordings of podcast episodes to produce standalone MP3 files for audio-only distribution.
Meeting Recording Analysis
Extract audio from recorded video meetings so the audio can be analyzed for speaker sentiment or summarized by an AI block.
Subtitle Generation Pipeline
Use extracted audio as an intermediate step in a workflow that generates subtitles or closed captions for video content.
Language Translation Workflow
Extract audio from a video file and route it through transcription and translation blocks to produce multilingual text output.
Audio Content Archiving
Automatically strip audio from a library of video files and store the resulting MP3 URLs for long-term audio archiving.

Get Started FreeCommon questions about Extract Audio from Video
What are the required parameters for this block?
The block requires two fields: a video URL (the source video file to extract audio from) and a destination variable name (where the output audio URL will be saved for use in later steps).
What does this block return?
The block saves a URL pointing to the extracted MP3 audio file into the variable name you specify in the destinationVar field. That variable can then be referenced by subsequent blocks in the workflow.
What format is the extracted audio saved in?
Based on the block description, the extracted audio is saved as an MP3 file.
What kinds of workflows commonly use this block?
This block is typically used as a preprocessing step in workflows that involve speech transcription, audio analysis, subtitle generation, or any pipeline where audio needs to be handled separately from its source video.
Can the output audio URL be used directly by other blocks?
Yes. The extracted audio URL is stored in the destination variable you configure, and any subsequent block in the workflow that accepts a URL or variable reference can use it.
