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.
A piano track would have been so much easier to notice the difference...
I focused on the hi-hat, personally.
I was eventually able to nail it (Silver Ears level - Details - MP3 Arefacts) and felt extremely happy once I did. Initially I thought I’d never make it, and I really didn’t think training would help either as I’ve been listening critically to music and different headphones for several years. However, to my big surprise training does seem to help. So, to anyone reading this being stuck, my advice is to keep listening, and when you do get tired take a break and come back later. If you keep listening your listening skills will improve even though you may not think so. I should add that I suffer from tinnitus but (with quite a bit of training) was still able to nail it.
I think I focused mainly on the voice and the bass. The bass seemed more or less constant and so helped to contrast the voice which would have an ever so slightly brighter presentation in the low mid-range with more MP3 artefacts. Yes, perhaps a piano would have been a better example in this challenge. It would have been nice to be able to choose from a few different examples. Perhaps something that can be suggested to Philips!
