Audio2TextJS is a Node.js library for audio processing and transcription using the Whisper tool. It supports converting audio files to text using various pre-trained models.

• Convert audio files to text with customizable options.
• Automatically downloads necessary model files.
• Supports multiple output formats: JSON, TXT, CSV.
• Flexible configuration for threading, processors, and more.

To install the library, use npm:

npm install audio2textjs

import Audio2TextJS from 'audio2textjs';

// Example usage
const converter = new Audio2TextJS({
    threads: 4,
    processors: 1,
    outputJson: true,
});

const inputFile = 'path/to/input.wav';
const model = 'tiny'; // Specify one of the available models
const language = 'auto'; // or specify a language code for translation

converter.runWhisper(inputFile, model, language)
    .then(result => {
        if (result.success) {
            console.log('Conversion successful:', result.output);
        } else {
            console.error('Conversion failed:', result.message);
        }
    })
    .catch(error => {
        console.error('Error:', error);
    });

The library includes the following models:

| Model     | Disk   | RAM     |
|-----------|--------|---------|
| tiny      |  75 MB | ~390 MB |
| tiny.en   |  75 MB | ~390 MB |
| base      | 142 MB | ~500 MB |
| base.en   | 142 MB | ~500 MB |
| small     | 466 MB | ~1.0 GB |
| small.en  | 466 MB | ~1.0 GB |
| medium    | 1.5 GB | ~2.6 GB |
| medium.en | 1.5 GB | ~2.6 GB |
| large-v1  | 2.9 GB | ~4.7 GB |
| large     | 2.9 GB | ~4.7 GB |

Creates an instance of Audio2TextJS with optional configuration options.

• options (Object): Optional configuration settings for the converter.

const converter = new Audio2TextJS({
    threads: 4,
    processors: 1,
    outputJson: true,
});

Runs the Whisper tool for audio processing and transcription.

• inputFile (string): Path to the input WAV file.
• model (string): Name of the model to use (tiny, base, etc.).
• language (string): Spoken language ('auto' for auto-detect).

A Promise that resolves with an object containing success status, message, and optional output upon completion.

converter.runWhisper('path/to/input.wav', 'tiny', 'auto')
    .then(result => {
        console.log('Conversion result:', result);
    })
    .catch(error => {
        console.error('Error:', error);
    });
