Detailed explanation-1: -The more bits you use to record each sample, the better the sound reproduction. In other words, a high sample rate along with a high bit depth (AKA ‘bit rate’ or ‘sample format’) will deliver the best audio quality in your recording. The higher the bit depth, the higher the dynamic range.
Detailed explanation-2: -If you’re recording music, a standard sample rate is 44.1 kHz or 44, 100 samples per second. This is the standard for most consumer audio, used for formats like CDs. 48 kHz is another common audio sample rate used for movies.
Detailed explanation-3: -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.
