Known Limitations

Shazam API Call Limit (Error 429)

Shazam allows up to 20 requests per minute. Hence, a proxy is recommended to speed up recognition when using --mixtape.

12 Second Duration Limit per request

The maximum sample duration that Shazam allows is 12 seconds. Any audio after 12 seconds will not be recieved by Shazam.
