Downsampling. Nearly all master digital studio recordings are made at higher sample rates and bit depths than a CD can handle, even if it’s only 48kHz. For example, Keith Johnson at Reference records all their materials at 176.4kHz/24 bits and nearly every recording studio is making masters at 96kHz/24 or higher.

To downsample (also called decimate) your signal (it means to reduce the sampling rate), or upsample (increase the sampling rate) you need to interpolate between your data. The idea is that you need to somehow draw a curve between your points, and then take values from this curve at the new sampling rate.

and your equation for re-sampling this re-constructed signal is: x [ m] = ∑ n x [ n] s i n c ( ( m T 2 − n T 1) / T 1) for m=0,1,...,length of downsampled signal at the new rate (8000 hz) and T 2 is its period. The inner summation on n must be computed for each output m value, necessary to generate the resampled signal x [m]
Q. What’s the best way to downsample? - Sound on Sound

I have no problem understanding dithering 24-bit audio to 16-bit, but am less clear about downsampling. Before attempting to master (once the mix is done and in stereo format) I take the file and downsample from 96kHz to 44.1kHz, but there is a definitely noticeable degrading of the high end when I’ve done this.

Filtering and Downsampling Because downsampling by Nwill cause aliasing for any frequencies in the original signal above |ω|>π/N, the input signal must first be lowpass filtered. H(z) N The lowpass filter h[n] is an FIR filter of length Mwith a cutoff frequency of π/N. Let’s draw the FIR filter hin direct form: h(0) y[n] z-1 h(1) h(2 ...
