- Also, lower sampling rates generate more audible aliasing frequencies.
- Aliasing frequencies are always present - even at 44kHz. But at
- 44kHz, they are inaudible because of their high pitch. They are also
- most likely filtered out by most CD players/soundcards, etc, since a
- lowpass filter that filters sounds above 22khz is not going to audibly
- effect the frequency response like a 11kHz lowpass filter would.
- (Unless you are a dog!!)
-
- These aliasing frequencies aren't necessarily 'Noise', although they
- definitely contribute to a loss of sound quality along with the
- limited frequency response.
