Shazam Api for node-js

This library is heavily based on Numenorean's work.

Usage:

import { Shazam, s16LEToSamplesArray } from 'shazam-api';
import fs from 'fs';

const shazam = new Shazam();
const fileContents = fs.readFileSync("test.pcm");
const samples = s16LEToSamplesArray(fileContents);

const songData = await shazam.recognizeSong(samples);
console.log(songData);

The data passed to s16LEToSamplesArray needs to be raw PCM with:

• Sample rate set to 16000Hz
• Bit depth set to 16 bits
• 1 channel of audio

Such a file can be generated with ffmpeg using the command:

ffmpeg -i <source file> -ar 16000 -ac 1 -f s16le test.pcm

Or within node or the browser thanks to ffmpeg.wasm
