Combatting Alert Fatigue by Prioritizing Malicious Intent
In 2023, data breaches surged 78% from zero-day and supply chain attacks, but developers are still buried under alerts that are unable to prevent these threats.
High performance WAV decoder and encoder. The decoder is up to 750x faster than the 'wav-decoder' npm module.
In addition, in contrast to 'wav-decoder' the result is returned directly instead of with a promise.
This module combines the functionality of 'wav-decoder' and 'wav-encoder'.
let fs = require('fs');
let wav = require('node-wav');
let buffer = fs.readFileSync('file.wav');
let result = wav.decode(buffer);
console.log(result.sampleRate);
console.log(result.channelData); // array of Float32Arrays
wav.encode(result.channelData, { sampleRate: result.sampleRate, float: true, bitDepth: 32 });
Data is always returned as Float32Arrays. While reading and writing 64-bit float WAV files is supported, data is truncated to 32-bit floats.
This module assumes a little endian CPU, which is true for pretty much every processor these days (in particular Intel and ARM).
