How does sample rate conversion work?

The more samples per second, the higher the accuracy of the digitized sound. The Nyquist Theorem states that if you divide the sample rate by 2, the resulting number represents the highest frequency that can be reproduced by that sample rate. Thus, 48,000 samples / 2 = 24,000 Hz.

Can you convert 44.1 kHz to 48kHz?

To do this, open the audio using a free audio editing software, such as Audacity. Once you have the audio loaded, go to Project Rate (Hz), which is at the bottom left of the program, and then click on the V sign and change it from 44100 to 48000, and then go to File>Export>Export as WAV and then click on Save.

Why do we use sampling rate conversion?

Sample-rate conversion prevents changes in speed and pitch that would otherwise occur when transferring recorded material between such systems.

Does sample rate conversion affect sound quality?

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.
