On: A Sleeping Alexa Can Listen for More Than Just Its Name

I'm aware I don't know what I'm talking about.

But the love.wav gives a bit rate of 768kbps, 6 sec of audio at 571 KB storage size.

Another poster also did the math on 5.6 kbit/s (700 bytes/s).

> 5.6 * 60 * 60 / 1024 / 8 = 2.4609375 MB/hr

But should that 5.6 not be 768 to get love.wav voice quality? What am I missing like a moron?

Thanks for the example and anecdote, something to actually grasp in trying to understand the problem.

The wav file is decompressed, so you can’t just look at the size of the file.

I'm not looking at the file size. I'm looking at the kbps the os reported for the wave file, which is 768kbps. Where 6 Kbit/sec mentioned.

The reported kbps is just the file size divided by the duration.
