I will be the first to admit 44.1 isn't perfect, because it cuts 20kHz a little too close, resulting in very slight attenuation of frequencies above 18.5kHz. The sample rate needs to be a little more than twice the highest audible frequency. But if your 16bit, 44.1kHz CD sounds bright, consider what makes it bright and you will see that it's a false bright created by the high frequencies sounding like square waves!! DVD is already up to 24 bit 96kHz sampling so we are on the way. In an article by Rupert Neve, I read recently, he said that we should aim for 24bit resolution and 192kHz sampling rate if we want to equal the quality of high quality analogue recording. Pigs Bum.Īt a sampling rate of 96kHz you get 9.6 samples of a 10kHz wave and believe me, you can hear it. That is why digital high frequencies sound harsh!! The industry has constantly denied this factor and even gone to the extent of saying the hear can't distinguish between a square wave and a sine wave above 7kHz. imagine how inaccurate 4.41 samples are of a complex waveform. In that drawing we took 6 samples of the waveform and got an amplitude reading saying 0,2,2,0,2,2. But 10kHz will have 4.41 samples taken of each of it's waveforms.
