```

```bash
# Loop the recognition continously and save the logs as CSV file
pyzam --speaker -d 10 --write --loop

# Listen to mixtapes and save the logs as CSV file
pyzam --input audio_file.mp3 --duration 12 --mixtape

## 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 Sample Limit per request
The maximum sample duration that Shazam allows is 12 seconds. Any audio after 12 seconds will not be recieved by Shazam.
