Check the Tuning Frequency of Your Music, Loop or Sample

Most modern music is tuned to “Concert Pitch” (A=440Hz), but many producers prefer alternatives like 432Hz or 442Hz.

If you are trying to tune a synthesizer to an obscure sample, a musician playing along to a recording, or a listener curating a 432Hz playlist, knowing the exact reference pitch is essential. Use the tool below to analyze your audio instantly.

Tuning Frequency Detector FAQ:

What is a Tuning Frequency Detector?

This tool above analyzes the audio spectrum of a song to find the reference pitch of the note “A.” While the global standard is 440Hz, this detector identifies deviations, allowing you to see if a track was produced in 432Hz, 444Hz, or other non-standard tunings.

What is the difference between 440Hz and 432Hz?

440Hz (Concert Pitch): This is the ISO standard used by orchestras, pop music, and instrument manufacturers since the mid-20th century to ensure consistency.
432Hz (Verdi’s A): Many musicians and listeners prefer 432Hz, believing it provides a warmer, clearer sound. It is frequently used in ambient, meditation, and “healing” music.

Why is knowing the Reference Pitch important?

For music producers, matching tuning is critical. If you try to play a software instrument tuned to 440Hz over a sample or recording that is tuned to 432Hz (or even 440.5Hz), the result will sound dissonant and out of tune. You must identify the frequency of the recording first, so you can tune your instruments to match it.

Does this tool work for samples and field recordings?

Yes. You can run the tool using any sample, loop, track or audio file and you should get a good result.

How do I change the tuning of a song?

Once you have detected the frequency, you can re-pitch audio in Digital Audio Workstations (DAWs) like Ableton Live, Logic Pro, or FL Studio. To convert 440Hz audio to 432Hz, you typically pitch-shift the audio down by approximately -32.
