quantization noise step ratio calculator online

Use quantization noise step ratio online for bit depth. Normalized bipolar full-scale range; ideal uniform quantization error, not an audio dither generator. Ideal mathematical audio model with supplied values. Real speakers, rooms, hearing exposure and converter performance are not measured.

How to use it

Enter bit depth. Select Calculate and check the labeled output. Copy or download the JSON result.

Options and example settings

OptionChoices / valueExample default
bit depthMain input. Whole numbers. 16

Calculation method

quantization_step = 2/2^integer(bit_depth,1,32); uniform_error_rms = 2/2^bit_depth/sqrt(12) (^ means exponentiation; trig functions ending in d use degrees).

Worked examples

Apply quantization noise step ratio to the case below, keeping the displayed units and assumptions. Normalized bipolar full-scale range; ideal uniform quantization error, not an audio dither generator.

Choose the right tool

Choose timing tools for tempo and samples, tuning tools for frequency ratios, and level tools for amplitude or power. Coherent signal addition differs from independent-source addition; acoustic room estimates assume simplified conditions.

Limitations and common mistakes

  • Normalized bipolar full-scale range; ideal uniform quantization error, not an audio dither generator. Ideal mathematical audio model with supplied values. Real speakers, rooms, hearing exposure and converter performance are not measured.
  • Use the displayed unit in every field. Ratios and percentages are different inputs; percent fields use values such as 25 rather than 0.25.
