What is sampling rate?


Sampling rate is a most important parameter that determine audio quality. The sampling rate is the number of samples of a sound that are taken per second to represent the audio. The more samples taken per second, the more accurate the digital representation of the sound can be.

Why do I need to convert sample rate?


All audio formats and audio hardware support only limited range of sampling rates. Here is a few cases when you need to convert sampling rate:

  • HD audio formats support up to 192 Khz sampling rates, but common audio formats support only sampling rates from 8000Hz to 48000Hz
  • MP3 compression quality depends from sampling rate, you can not use 256Kbps or 320Kbps bitrates for low quality audio files.
  • AMR codec support only 8000Hz and 16000Hz sampling rates
  • Audio CD support only 44100Hz sampling rate

Audio Converter Plus will take care about sampling rate conversion automatically, but you can force it to use any frequency in codec settings.
