Commandline Additions To Customize For My Hearing?

I can seriously hear the crickets chirping. Where is everyone around here? Is anyone able to respond? SOS! SOS! Probably the "gurus" wonder if you've read this board the last few weeks... All discussions about the new LAME versions, Dibroms own tunings, Gabriel's --alt-preset medium settings etc. deal with lower bitrates (with equal quality) than the usual aps files, as far as I remember. Furthermore Hydrogen Audio is not part of the Civil Service yet, if I'm not mistaken, so they don't have to be on duty 24 hours a day... The truth is that no one can fully answer your question for you , because it is your prefered music, your hardware, your ears, your brain, your mood, so you have to do it by yourself . And if you find out that it's too hard for you, then go for the lower quality and "don't worry, be happy". For example I just did a quick test with LAME 3.92 and --alt-preset standard --lowpass 17.5 and found out that this command line worked (= the preset did not ignore my chosen lowpass setting). I also encoded the c't reference.wav with the usual aps setting and compared these three files for a while. I could not find any obvious differences between them, but I spent only about an hour on that. The only thing might be a tiny little bit of dirt in one sibilant that the --lowpass 17.5 setting showed in comparison to the original or the aps file. So does this fully answer your question? Probably not, because you don't know with what kind of music I heard this one little artifact and if I will hear it again tomorrow or maybe tonight. And I don't know if you are a hardcore headbanger that likes to listen to screaming guitars and aggressive crash cymbals all the time, which might afford another setting or even another compression format. Get what I mean? By the way, the resulting bitrates were 169 kbps for the aps file and 164 kbps for the one with the added lowpass, so not the 10 kbps difference you're aiming at. But again, with other music this could probably come out like you expected. And choosing another format is probably not an option, if I consider your nick name.
