Enter the bit depth (bits) and the sampling frequency (hz) into the Calculator. The calculator will evaluate the Audio Data Rate. 

Audio Data Rate Formula



  • is the Audio Data Rate ()
  • is the bit depth (bits)
  • is the sampling frequency (hz)

To calculate Audio Data Rate, multiply the bit depth by the sampling frequency.

How to Calculate Audio Data Rate?

The following steps outline how to calculate the Audio Data Rate.

  1. First, determine the bit depth (bits). 
  2. Next, determine the sampling frequency (hz). 
  3. Next, gather the formula from above = ADR = BD * SF.
  4. Finally, calculate the Audio Data Rate.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

bit depth (bits) = 123

sampling frequency (hz) = 144
