Shazam Api for JavaScript

This library is heavily based on Numenorean's work.

Usage:

import{Shazam,s16LEToSamplesArray}from'shazam-api';importfsfrom'fs';constshazam=newShazam();constfileContents=fs.readFileSync("test.pcm");constsamples=s16LEToSamplesArray(fileContents);constsongData=awaitshazam.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

Using within a browser

To use this project within a browser, you need to deploy a userscript which will let you bypass CORS while accessing the Shazam servers.
