Quickly perform the calculations to convert Hertz (Hz) to Milliseconds (ms), hertz to samples, & hertz/frequency to note.

Use this tool to precisely time oscillators, LFOs, filters, and other frequency-based audio effects in Ableton Live, FL Studio, Pro Tools, and other commercial or custom built audio software/plugins.


What is Hertz (Hz) ?
In audio, Hertz (Hz) is the unit of frequency, representing the number of cycles per second of a waveform. It's fundamental to understanding pitch, timbre, and various audio effects.

Note & Sample Measurements
Included in the conversion results is the equivalent note & octave of a given frequency, as well as the minimum number of samples required to fully resolve an entire period of an audio signal with the same fundamental frequency at different sample rates.

Yamaha (Scientific Pitch Notation) vs Roland:
DAWs & other audio programs map frequencies to different octaves depending on their choice of pitch notation. It is more common to have 440 hz map to A4 - this is referred to as Scientific Pitch Notation, or Yamaha notation. However, several popular DAWs use Roland Pitch notation, which shifts these measurements down an octave. Notable software that use or support Roland pitch notation include Ableton Live and Pro Tools.

Hz/Ms to Samples
The columns marked with "samples" indicate the number of audio samples for a full cycle of a waveform to occur at common audio sample rates. This is calculated based on the milliseconds value given for the inspected frequency.
While the millisecond values in the table feature a degree of precision, the sample values will always be whole numbers, as samples are discrete and, in practice, cannot be fractional at constant sample rates. Thus, if the resulting value is fractional, it is rounded up to the nearest whole number before display, giving us the minimum number of samples required for one full cycle of an audio signal at that given frequency.


The Hz to ms Formula:
1 second = 1000 milliseconds (ms)
To get the duration of one cycle of a waveform at any frequency in Hertz, we divide the number of milliseconds per second by the frequency. So:
1000 (ms) ÷ Hz = duration of one cycle in milliseconds
Example:
1000 ÷ 440 Hz = 2.273 ms per cycle

For your convenience, the following table uses the frequencies of the first 8 octaves of each note to provide a quick lookup table with their associated Hz values, duration in milliseconds, and samples. We start at C0, where C0 equals 16.32150 hz, consistent with Yamaha/Scientific Pitch Notation using standard tuning.
