Package Exports

n8n-nodes-asr
n8n-nodes-asr/dist/nodes/Asr/Asr.node.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (n8n-nodes-asr) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

n8n-nodes-asr

A custom n8n node for automatic speech recognition (ASR), supporting audio file upload, format conversion, and integration with external ASR services.

Features

Download audio files from a URL and handle redirects
Automatic format detection: if the input is already standard WAV (pcm_s16le, 44.1kHz, stereo), upload directly; otherwise, convert using ffmpeg
Supports custom ffmpeg parameters (default: 44.1kHz, stereo)
Multipart/form-data upload compatible with FastAPI and other ASR backends
Returns parsed ASR results in n8n workflow

Installation

npm install n8n-nodes-asr

Usage

Add the node to your n8n custom nodes directory or install via npm.
Configure the node with your ASR service URL and API key.
Provide an audio file URL as input.
The node will download, (if needed) convert, and upload the audio to your ASR service, returning the transcription.
