nearest fft bin for target frequency calculator online

Use nearest fft bin for target frequency online for frequency Hz, sample rate Hz, fft size. Ideal mathematical audio model with supplied values. Real speakers, rooms, hearing exposure and converter performance are not measured.

How to use it

Enter frequency Hz. Set sample rate Hz, fft size. Select Calculate and check the labeled output. Copy or download the JSON result.

Options and example settings

OptionChoices / valueExample default
frequency HzMain input. Zero or positive values. 1000
sample rate HzOption. Positive values. 48000
fft sizeOption. Whole numbers. 4096

Calculation method

nearest_bin = round(range(frequency_Hz,0,sample_rate_Hz/2)*fft_size/sample_rate_Hz); bin_frequency_Hz = round(frequency_Hz*fft_size/sample_rate_Hz)*sample_rate_Hz/fft_size (^ means exponentiation; trig functions ending in d use degrees).

Worked examples

Apply nearest fft bin for target frequency to the case below, keeping the displayed units and assumptions. Ideal mathematical audio model with supplied values. Real speakers, rooms, hearing exposure and converter performance are not measured.

Nearest FFT Bin for Target Frequency — worked case

Settings: sample rate Hz: 48000; fft size: 4096

Input:

1000

Calculated result for these inputs:

Output:

{
  "nearest_bin": 85,
  "bin_frequency_Hz": 996.09375
}

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

  • 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.
