Can you hear like an audio engineer?

Hello, my name is Matt. I record, edit, and mix music for a living. My profession requires an extremely discerning ear. This little listening test is to see if you can pick up subtle differences in pitch.

What I have below is a series of approximately 1khz sine waves, in sets of two. In each test I’d like you to try to discern which tone is sharper than the original tone. Pitch is measured in tones, and cents. A semi-tone is considered one pitch. Thus, A# is a semi-tone higher than A. A cent is a percent of a tone. So 50 Cents up from A would be half way between A and A#.

Supposedly, the smallest discernible difference in pitch is +/- 6 Cents. That’s a 1/16th of the way to the next semi tone. So, we’ll start off just by comparing a tone and a tone that is 50 Cents sharper. Then we’ll move down the ladder, to 25 Cents, 12 Cents, etc. Personally I find 12 Cents to be difficult to identify, and I’ll concede that it’s easier to hear pitch difference when two sounds are played simultaneously.

    I got all 4 correct…but, It would be far better to have dedicated players for these test instead of having to use WMP or QT player.

    Having forgotten my own answers I was able to find this not terribly difficult. The last two are pretty easy to identify by “feel”.

    4 correct out of 4? Wow. Are you sure this are small differences? Works fine with Firefox 3.6.12 with VLC opening the files external to FF.

    what does it mean, a sound is ‘sharp’ or one sound is ‘sharper’ then the other?

    I got them all right, not surprising since I am a composer who works mainly with computers.
