How to Use This Calculator
  1. Enter Source Sample Rate, Target Sample Rate, and Bit Depth.
  2. Set File Duration.
  3. Review the Frequency Loss (Hz) result.
  4. Use Source Nyquist Freq (Hz) and Target Nyquist Freq (Hz) to inform your decision.
  5. Use the chart to visualize the results and explore different scenarios by adjusting inputs.

How the result changes with Source Sample Rate

What each input means

Source Sample Rate
Original sample rate of the audio file.
Target Sample Rate
Desired output sample rate.
Bit Depth
Bits per sample: 16 for CD, 24 for studio, 32 for float.
File Duration
Length of the audio file in seconds.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Source Sample Rate = 96000, Target Sample Rate = 44100, Bit Depth = 24, File Duration = 180 = 4 input(s) provided
  2. Calculate Frequency Loss
    Frequency Loss
    25950 = 25950
  3. Calculate Source Nyquist Freq
    Source Nyquist Freq
    48000 = 48000
  4. Calculate Target Nyquist Freq
    Target Nyquist Freq
    22050 = 22050
