Digitising a signal - sampling rate and resolution

# data[].attributes.body
The sample rate decreases by half after each “beep”. The first beep (at 30s) barely changes the quality. An apparent change in tempo might be heard in the final two very low sample rates: this distortion known as aliasing and occurs when high frequency sounds are sampled at low frequ ency sampling rates.
