why nero AAC cut frequency at the peaks? 2016-01-31 06:46:06 I start using AAC just several days ago, before that, I use lame V2 setting to compress my music collection.I came across this CD, which I can't not understand the spectrogram. See attached png file and flac file.I use foobar and nero AAC setting -q0.55 converting to .m4a file. The spectrogram shows that nero like to cut those strong peaks, while preserves more weaker peaks. I can't understand this, I thought the peaks should be given more bitrates? Am I wrong?
