The cutoff frequency for a low-pass filter is that frequency at which the output (load) voltage equals 70.7% of the input (source) voltage. Above the cutoff frequency, the output voltage is lower than 70.7% of the input, and vice versa.

How do you calculate the output voltage of a low-pass filter?
The output voltage of an RC low-pass filter can be calculated by treating the circuit as a voltage divider consisting of a (frequency-independent) resistance and a (frequency-dependent) reactance.
What happens in low-pass filter?
A low-pass filter is a filter that passes signals with a frequency lower than a selected cutoff frequency and attenuates signals with frequencies higher than the cutoff frequency.
How do you read a low-pass filter?
What is a low-pass filter? A low-pass filter (LPF) is an audio signal processor that removes unwanted frequencies from a signal above a determined cutoff frequency. It progressively filters out (attenuates) the high-end above its cutoff frequency while allowing the low-end to pass through, ideally without any changes.
How many Hz is a low-pass filter?
Using real cutoff frequency values for the low-pass filter in Wwise would have looked something like this: LPF on Sound = 13,500 Hz. LPF on Container = 7,000 Hz.
