No one is born with the innate knowledge of what 250Hz sounds like. It'a a learned skill. It is a skill you need to practice to eliminate the hours of guess work you waste when mixing records and looking for bothersome peaks or holes in your tracks.

The pureMix Frequency Quiz will help you memorize the sound of crucial frequency and ranges and will help you speed up the equing process drastically over time.

The audio spectrum is divided in 10 octaves. The Quiz's first 3 levels will focus on the lower, middle and higher 5 octaves of the spectrum. Once you feel confident, you can challenge yourself with all the octaves simultaneously.

How To Use: To start the Quiz, click on the big play button. You'll hear flat pink noise for reference and then a couple seconds later you'll hear the noise change tone. An equalizer was used to apply a 14db boost to a specific frequency. The goal is to identify which frequency is being boosted. Select your choice and the system will give you the correct answer. In between guessing phases, you can click on each frequency in order to hear it and train your ear. Click the play button again for the next frequency quiz.

There are 10 samples per test. Stay focused. The frequencies picked are truly random so the test will be different every-time.(If you are taking the test on earbuds or laptop speakers => you are missing out and fooling yourself).

Have fun. Test yourself often. Get better faster.
