For each test, listen to the test sound and the reference sounds, decide which reference sound is the nearest in note or pitch to the test sound, and select it with the radio button to the right of the sound. The first time you play each sound, it might take a moment to download. After that, it should play instantly. If you have problems playing the sounds on your computer, see here. You can listen to each sound as many times as and in whatever order you like. Once you have chosen the reference sound you believe best matches the test sound, it helps to repeatedly listen to the reference sounds either side of the one you have chosen against the test sound to make sure that one sounds lower in pitch, and the other higher, than the test sound. When you are happy with your selection for each of the tests, answer the questions at the bottom of the page and click the 'Send results' button. Depending on the test setup, your test results will be displayed on the screen for printing, saved to disk or emailed to me automatically.
