I need real time noise monitoring device with computer interface. Only current SPL value is needed. Do anybody knows answer to these few questions: (XL2 and remote option)
- How much delay there is
between “real sound” and streamed value?
- How old is that value when you get it on PC? e.g. if I clap my hands now, when I get that clap value on my python code? (how many milliseconds)
- How many times per second the SPL value can be read with PC?
by experiment, we found that one can query up to 100 SPL readings per second.
The average latency between the sound occurance and the reporting in the remote control measurement is around 10ms
I hope this helps.
