Sometimes, I use https://theproaudiofiles.com/quiztones/ (iOS + Mac)

I have a German app called "Das absolute Gehör" where you can train intervals, scales and modes, chords and inversions. It's good, I play it frequently

I used to train using differents compressors and EQs in the same track in my DAW, and notice the difference bettwen each one

I do more music theory-based ear training as well. Intervals, chords, etc.

I would like to be able to do some interval/ chord training as mentioned above within soundgym or is there another good program people here would recommend.

The Rick Beato app seems pretty intensive. I just don't have the time for another program right now.

I use quiztones a bit. Also SAE has a good (and free to download) frequency recognition app where you can download your own .wavs in for training (On the mixes you're working on!).
But SoundGym takes the cake.

@Patrick Palardy can you give us a link to the SAE app?

I use 'trainyouears' EQ Knight/Peak Master/Kit Cut on steroids ... you can use your own files, design your own excercises (setting frequencies, db amount of boost/cut, Q factor)
Also Harman-Kardon has its own free app that you can download.

@Alice Minguez, here it is.

Quiztones to keep those frequencies in the memory and Tonedear for interval ear training

I often use StudioEars2,Complete Ear Trainer,and Syntorial. And then,I don’t use it by now but Theta music trainer is also provide EQ and mix training.
You can find more further app or software by using ‘ear training app’ as search word

Complete ear trainer, but is more a musical type of exercises (intervals, chords recognition, etc)

As mentioned by others above, Complete Ear Trainer is a useful tool. Its focus is more on the musical side, but being able to identify intervals effectively will aid your overall development. Its kind of like an alternative way to train the same information. Plus its mobile so you can stay fresh where ever and when ever. I've also found the Audio Training app to be helpful, its simple, bare bones frequency identification and EQ sweep.

thanks @Alice Minguez
