The sampling speed determines the amount of data per second received. Larger values give a more exact calculation.
Gain is a factor by which the input signal is amplified.
Low pass filter
A low-pass filter is a filter that passes low-frequency signals and attenuates signals with frequencies higher than the reference frequency.
High pass filter
A high-pass filter is a filter that passes high-frequency signals and attenuates signals with frequencies lower than the reference frequency.
Band pass filter
A band-pass filter is a filter that passes frequencies within a bandwidth around the reference frequency and attenuates frequencies outside that range.
Describes the relative loudness perceived by the human ear.
