Audio Frequency Trainer
This game teaches you how to identify audio frequencies. It's suitable for anyone from beginner to audio professional.
How it works: You listen to a series of test tones and identify the frequency of each one as you go. At the beginner level you are tested on four different frequencies, then you can work your way up to guru level with all 31 frequencies. Full instructions are below the test panel.
Before you start, turn your volume down, then click here to play a test tone and set your volume to a comfortable level.
STEP 1: PREPARATION
- Each of the 31 buttons above corresponds to a different frequency. Lower frequencies are towards the left, higher towards the right.
- To learn what different frequencies sound like, click the speaker icons below the frequency buttons.
- You probably won't be able to hear the lowest and the highest tones (this depends on both your hearing and your speakers). You can set the minimum and maximum frequencies so that only the tones you can hear will be used.
- Once you've got a basic idea of what the different frequencies sound like, you're ready to start testing.
STEP 2: TESTING
- Click NEW TONE to hear a random test tone.
- Guess the frequency of the tone and click the corresponding button (it will be one of the highlighted ones).
- If necessary, use the Replay/Pause buttons to hear the tone again.
- Keep guessing until you get the correct frequency.
- Click NEW TONE to continue with a new tone.
- As you get better, select a higher difficulty level (Intermediate, Pro, Guru).
Notes
- Frequencies are shown in Hertz (cycles per second). The letter 'k' indicates kHz (thousand cycles per second).
- Preview buttons do not work while you're taking a test.
- To use the Guru level you'll need speakers capable of reproducing 20 Hz - 20 kHz.
More About Frequencies
- 20 Hz - 20kHz is the maximum range of frequencies that humans can hear. You can use this test to see what your own hearing range is (assuming your speakers are actually capable of reproducing all these frequencies).
- The human voice peaks around the 1 - 3 kHz region.
- The standard test tone many people are familiar with is 1 kHz.
- Identifying frequencies is an important skill for sound engineers when performing tasks such as mixing and controlling feedback.
- The 31 buttons above represent the audio frequencies used in a professional 31-band graphic equalizer.
