Detailed explanation-1: -A high sample rate and a higher bit depth both increase the amount of information in an audio file and likewise increase the file size. Just like some photos have a high resolution, audio files with a high sample rate and high bit depth have more detail. Having more detail generally requires a higher bitrate.
Detailed explanation-2: -When the sampling rate (Fs) is increased, the distance between the maximum frequency content Fm and Fs/2 will increase. This increase in the gap between the maximum frequency content of the signal and Fs/2 will ease requirements on the transition bands of the anti-aliasing analog filter.
Detailed explanation-3: -The more samples you take-known as the ‘sample rate’-the more closely the final digital file will resemble the original. A higher sample rate tends to deliver a better-quality audio reproduction. Sample rates are usually measured per second, using kilohertz (kHz) or cycles per second.
Detailed explanation-4: -Even so, super high sample rates like 96 kHz or greater increase the size of your audio files a lot. Despite the extra size, you may not hear a big difference in audio quality. 24 bit, 48 kHz is a good balance between quality and file size, so that’s what I recommend for most producers.
