Default Re: 24bit & 96khz?

The Nyquist theory states that the sampled data must be double the range of the maximum frequency the brain is capable of decoding and then some. One of the drawbacks of sampling is that at half the sampling rate a subharmonic frequency is generated so at 44.1k a low pass filter is applied to anything above 20k so this harmonic will be inaudible. Doubling the sampling rate to 88.2 or 96k means this subharmonic is at 44.1k and the filter is applie to any siganl above 40k which is well beyond the human range of hearing. Bit rate and sample rate or anlagous to a film strip. Bit rate being the size of the frame being captured and the sample rate being the frame rate. Larger Bits increase the the lower threshold of the dynamic range allowing you to record quieter signals with reduced noise.
