Train your ears to recognize boosts and cuts in frequency and take your mixes, recordings and productions to the next level with Quiztones EQ ear training for audio engineers, producers and musicians.

Quiztones uses tones and frequency-altered noise and musical loops (including source material from your own music library) to train your ears so you can intuitively identify frequency boosts, cuts and changes in level and develop more acute listening, EQ and frequency recognition skills.

Quiztones will...

• Improve your mixing, recording and EQ'ing chops
• Sharpen your ears and frequency recognition skills
• Help you achieve clarity in your mixes and recordings
• Develop an intuition for which frequencies to boost or cut
• Learn how to identify and remove problematic frequencies
• Help you identify and eliminate PA system feedback for live sound
• Remove the need to sweep for frequencies in a mix
• Help you get cleaner mixes by learning to use EQ like a pro

Quiztones cleverly uses quizzes to guide you through various training exercises.

Each EQ quiz includes four trainers:

• Easy frequency boost (+10 dB)
• Hard frequency boost (+5 dB)
• Hard frequency cut (-10 dB)
• Expert frequency boost (+5 dB – 1/3 octave)


• Import your own audio (via Music Library, iCloud Drive, Dropbox, etc.)
• Tones
• Pink Noise
• Piano
• Drums
• Strings
• Strings 2
• Orchestra
• Electric Bass
• Upright Bass
• Female Vocals
• Electric Guitar
• Acoustic Guitar
• ... and now 75+ Premium Loops in the new Quiztones Pro (with 5 levels per loop)

Each gain level comparison quiz includes two difficulty levels.

Why We Created Quiztones EQ Ear Training Apps ...

We thought there should be an easier way to learn how to use EQ, train your ears and expedite the path to getting professional quality mixes, recordings and productions.

When I was at music school ten years ago studying audio engineering and music production, my teacher turned an iMac around, pulled up an EQ in Pro Tools and started quizzing the class on which audio frequencies he was boosting or cutting in a mix. That's when it hit me — this should be an app, with various difficulty levels, a scoring system and the ability to import your own source material for quizzes that will teach you how to use EQ like a pro.

Fast forward to today — 40k+ app downloads later — and we're still more excited than ever to keep evolving Quiztones to help you take the quality of your mixes, recordings and productions to the next level.

Great app for the price

This had helped me a LOT. Not only can I determine frequency and gain changes much more easily after using it, I'm able to hear many suble differences in sound qualities that I couldn't before. The only reason I didn't give it 5 stars is because it would probably cut the time it takes to train your ears if it had an option to let the exercise keep playing until you tell it to go on to the next one. That way, you could hear the difference after you've already guessed it. That would really help to learn the differences more easily. The way it is now, it stops playing as soon as you guys correctly, so you don't get a chance to memorize how a particular change sounds. That's a pretty big oversight IMO.

Hi xaos, thank you for purchasing Quiztones! Currently the audio does continue playing for a short time after the correct answer is chosen, but we'll take a look and consider if it makes sense to extend that even further! Thanks, Dan

Great app

I would have given it five stars, if there have been an autoplay next option. This would give you the opportunity to take your eyes off the screen, so that you make your first guess from what you hear, not from what you see as available choices.

I don’t know what it is but I seriously could not hear the 10db boost in any of the quizzes. And I’m not crazy because I took the same piece of music and went to logic and boosted the same frequency up by 10 dB and it was an OBVIOUS boost but in the app the EQ boost was not there. If this is a bug then please fix it soon because I’m wasting my money.


I didn’t realize you had to toggle the on and off switch. You know if you could put that in as a message before the quiz started that would be great.

Hi Tony, we've added some clarification to the start screen notice about the Power button functionality. Thanks for using Quiztones! -Dan
