Ever since the day that we’ve been able to push sample rate higher than 44.1kHz, this question has appeared: What is the best sample rate for Audio, and can you actually hear the difference between 48kHz and 96kHz (or higher) sample rates?
Update: Information for supersampling D/A and A/D converters has been added to the entry. Please see the conclusion page for more information.
Before we get into this, note that I am not an audio engineer, or a scientist. I am a software developer, who is often too curious for his own good, resulting in weird new projects – like StreamFX. So take this with a grain of salt, and if you know better, do feel free to contact me!
This test is based on my own frequency visualizer tool available here. All tests are based on the humanly audible range of 20 Hz to 20kHz (for a healthy young adult). These tests do not take into account inaccuracies caused by the physical properties of the D/A or A/D converters, speakers and microphones.
