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, and lets you track your progress with a built-in score log.

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)


• iTunes/Music Library
• Tones
• Pink Noise
• Piano
• Drums
• Strings
• Strings 2
• Orchestra
• Electric Bass
• Upright Bass
• Female Vocals
• Electric Guitar
• Acoustic Guitar

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 — 50k app downloads later — and we're still just as excited to keep evolving Quiztones to help you take your mixes, recordings and productions to the next level.

This app has proven a great resource. The hardest part of mixing for me is identifying tones I want to change by applying EQ in some way. I finally feel like I can start to hone in more easily, and undoubtedly, with some more training, I will hear what I should be hearing more quickly. That will take (and has already taken to some degree) a lot of guesswork and trial and erorr out of the process. I highly recommend this app to anyone working in audio.

my music library does not work?

this app is a super helpful way to keep up my listening skills without having to go back to Golden Ears-- however, not very user friendly. it took me about five quizzes to realize how the "on" button for the eq worked (I thought my headphones were damaged because I couldn't hear any shifts), and the feature to use your own music library seems to not be working and I can't figure out how to trouble shoot/where to go to get help. I do not regret purchasing because I need the practice but not worth $15.

Developer Response ,

Hi Bee, we'll make it clearer on the Start screen that the power button toggles effects on and off. Regarding your music library, Apple doesn't allow apps to access DRM-Protected songs or Apple Music tracks, but any audio file that is unprotected will import.

Please email us at if you need any additional support. Thanks, Dan

App is great. No practice option

The app is great and so far has been great for training the ear but I find it pretty annoying that there is no option to practice. The phone app offers this for a 3rd of the price of the computer version. Since I know that this already exists in the cheaper app it really bugs me that I paid way more for less functionality. They need to update the app or offer the phone app for free if you purchased the ‘full’ version on the computer.

Developer Response ,

Hi Lowdozer, we're definitely planning to bring Practice Mode to Quiztones for Mac as a free update, but we wanted to add it to iOS first so we can collect feedback and iron everything out. Unfortunately Apple doesn't provide a way to bundle iOS and Mac since they are technically separate App Stores. Thanks for your support and please let us know if there's anything else you'd like to see! -Dan
