How to Convert an MP3 from 48000 to 44100 Hz

By James Red

Two sampling frequencies used in digital audio are 48000Hz and 44100Hz. While the human ear can barely detect the difference between the two, computers and other devices are a little bit more discerning. Some programs and players will read only MP3s encoded with a 44100Hz sampling rate, which is a problem if your MP3s are encoded at the higher 48000Hz rate. Thankfully, there are many different audio conversion programs that can take a file encoded at the higher frequency and create a new copy at the lower frequency.
