Audio Converter

A package for handling audio format conversion and processing in the TW2GEM project.

Features

- Audio format conversion between μ-law and PCM
- Sample rate conversion (8kHz to 16kHz, 24kHz to 8kHz)
- Base64 encoding/decoding support
- Audio quality optimization

Installation

``bash
npm install @tw2gem/audio-converter
`

Usage

`typescript
import { AudioConverter } from '@tw2gem/audio-converter';

// Convert μ-law audio to PCM 16kHz
const pcmBase64 = AudioConverter.convertBase64MuLawToBase64PCM16k(muLawBase64);

// Convert PCM 24kHz to μ-law 8kHz
const muLawBase64 = AudioConverter.convertBase64PCM24kToBase64MuLaw8k(pcmBase64);
`

API Reference
