Today I tried implementing my own simple low-pass filter using the pseudocode from Wikipedia as a starting point. Specifically, this code: for i from 1 to n y[i] := y[i-1] + α * (x[i] - ...
How is sample rate frequency related to audio frequency? For example, say I have an audio file with a sample rate of 44100 Hz, 1 byte per sample (256 different values), and, for simplicity, a single ...
If I record something that is at 500Hz audio frequency then the sampling frequency will still be 44.1Hz. How does the 500Hz audio frequency fits with 44.1KHz sampling frequency? If the sampling ...
Since our hearing range is said to be 20Hz to 20,000Hz. So, how can we possibly hear something at 44.1Khz? Or do we hear only half of the sound produced at 44.1Khz by any audio CDs? What is going on?
At its best transmission quality, what is the equivalent samplerate and bitdepth of FM radio? Thanks.
