MP3 Artifacts" challenge only have 4 questions

Just keep guessing if you lucky u will pass it

If I remember the little mathematics about statistics I once learnt, the likelihood is about 1 chance in 25 I’ll be able to guess it provided I’m able to nail 96 Kbps without guessing. Provided I don’t need to guess at 112 Kbps the odds increases to about 1 chance in 10. No, I don’t think this method will work for me. Thanks for the suggestion nevertheless!

Guessing four: (1/3) * (1/3) * (1/3) * (1/3) = 1.2 % (1 chance in 100)
Guessing three: (1/3) * (1/3) * (1/3) = 3.7 % (1 chance in 25)
Guessing two: (1/3) * (1/3) = 11.1 % (1 chance in 10)
Guessing one: (1/3) = 33.3 % (1 chance in 3)

Holy crap. Finally! That took way too long. Particularly difficult was the Frequency Bands on Music test in the Golden section. I must have spent an hour just going through that one training. Definitely something everyone should try out.

Edit: Uploaded a pic that actually showed the progress and completion date.

Congratulations! Impressive!

I got stuck at frequency bands in music,I got like 5/8 and then failed back to start. IMO everything else was pretty easy.

So mp3-compression was easy for you?
What exactly did you listen therefore to make it easy?

I was in the same shoes , I took a break for couple of days and had to concentrate to get through
At some point during that portion, my ears got too fatigued and I just couldn't even do the simple stuff anymore. Walked away for a couple hours and got through it a lot easier. If you're having problems with a particular area, walk away and come back.

I think it is good advice. I can now pretty well identify 96 Kbps and to some extent, 112 Kbps, but it still feels more or less impossible at 128 Kbps. My hope is that it actually is mostly about training, but I am far from sure that it's enough. It is easy to become exhausted and when that happens, nothing works. Additionally my tinnitus increases when I get pissed.

Thanks Aero Dynamic

A piano track would have been so much easier to notice the difference...

I focused on the hi-hat, personally.
