How FastWAV Accelerates Real-Time Audio Processing

FastWAV Tutorial: Integrating High-Speed Audio into Your App

Overview

• Goal: show how to encode, stream, and play WAV-like audio with FastWAV (a hypothetical high-speed WAV encoder/streamer).
• Assumed defaults: target platform — Node.js (server) + Web/React client; 16-bit PCM, 48 kHz sample rate, mono by default.

Server (Node.js) — encode + stream

1. Install (assumed package name):

   Code
   Copy CodeCopied
   npm install fastwav 

2. Encode PCM buffer to FastWAV:

   js
   Copy CodeCopied
   const FastWAV = require(‘fastwav’);
   // pcmBuffer: Int16Array or Buffer of 16-bit PCM samples
   const encoder = new FastWAV.Encoder({ sampleRate: 48000, channels: 1, bitDepth: 16 });
   const fastwavBuffer = encoder.encode(pcmBuffer);
   

3. Serve as HTTP stream (Express): “`js const express = require(‘express’); const app = express(); app.get(‘/audio.fastwav’, (req, res) => { res.setHeader(’
