50c Pitch Difference v/s Flat

Change the target here:  50c  20c  10c  5c  2c  1c 

Purpose

How good are you at spotting pitch (frequency) differences?

Files under test

The first audio file plays back a 440Hz sine tone characterized by a sudden increase in pitch occuring after 1s (50cent in this case). The second file introduces a decrease in pitch by the same amount. The third one is flat.

The Test

Warning. For best results, please use headphones to perform this test. Avoid using multiple speakers (a single speaker is OK) as the relative phase between the speakers will introduce frequency-dependent level changes. These changes in perceived loudness may help you to spot inaudible frequency changes.

For each column, tick the appropriate radio button. When the 10 files have been all labeled, click the "Submit" button to get your score. Reload the page as often as you want to perform new tests.

If you didn't pass this test with a score equal to 9 or higher, you possibly reached the limits of your hearing.

To make the test easier, one can use sawtooth tones instead of sine waves (the presence of harmonics in the sawtooth increases our perception of a change in pitch). To switch to the easier sawtooth test, click here.
