Octave Frequency Calculator

Calculate the frequency one octave above or below a given frequency. An octave is a musical interval where the higher note has frequencies exactly twice the lower note.

Calculation Formula

f₂ = f₁ × 2n

Where:
f₂ = Octave frequency
f₁ = Base frequency
n = 1 for higher octave, -1 for lower octave

How to Use This Calculator

  1. Enter the base frequency in Hertz (Hz) in the first input field. This is the reference frequency.
  2. Select whether you want to calculate the higher octave frequency or the lower octave frequency.
  3. Click the "Calculate" button to compute the octave frequency.
  4. The resulting frequency will be displayed along with the calculation details.

Understanding Octave Frequencies

An octave is a fundamental unit of pitch in music and acoustics. It corresponds to a frequency ratio of 2:1. This means that if you double a frequency, you've moved up one octave, and if you halve a frequency, you've moved down one octave.

Applications

This calculator is useful in various fields including:

  • Musical theory and practice
  • Audio engineering and sound design
  • Acoustic analysis
  • Electronic music production

Example

If you enter a base frequency of 440 Hz (which is the standard tuning frequency for the A4 note in music) and select "Calculate Higher Octave Frequency", the calculator will show 880 Hz, which is one octave higher.
