What is the sampling rate of 44.1 kHz?
The sample rate of 44.1 kHz technically allows for audio at frequencies up to 22.05 kHz to be recorded. By placing the Nyquist frequency outside of our hearing range, we can use more moderate filters to eliminate aliasing without much audible effect.
What happens when you convert sample rate?
Sample-rate conversion prevents changes in speed and pitch that would otherwise occur when transferring recorded material between such systems. More specific types of resampling include: upsampling or upscaling; downsampling, downscaling, or decimation; and interpolation.
Why is 44.1 kHz the standard sampling rate?
The exact sampling rate of 44.1 kHz was inherited from PCM adaptors which was the most affordable way to transfer data from the recording studio to the CD manufacturer at the time the CD specification was being developed.
How do I change the sample rate from mp3 to 44.1 kHz?
Visit the Export Settings window (File > Export > Adobe Media Encoder). In the Export Settings window, click on the Audio tab. In the Audio tab, there is a set of options called Basic Audio Settings. Click on the drop-down menu to the right of Frequency and change your audio sampling rate to 44.1 kHz.
