Should I convert all my audio to 256 AAC?

Hi all, I'm currently researching what the best route is to go with when converting over my CD library. I realize that everyone loves Lossless (which I'll use for archiving the CD's) but I'm looking for "the best" lossy encoding. Two years ago I chose Nero AAC -q0.65 (via dbPowerAmp) for portable listening (TMo Vibrant and a pair of Yuin PK2 earphones), after having done some ABXs with similar bitrate VBR Lame encodings. I'm happy with it, I barely notice any artifacts (mostly blues and jazz) but on some classical music files. Needless to say, the advantage over my old LAME 128kbps CBR files is obvious. I guess you could come to different conclusions, so you'd better do some blind tests with different encoders (and music genres) at similar bitrates.Yeah, the thing is that I have a LOT of music to convert....and it's not just converting but properly tagging with artwork and putting it in the exact format I like within the itunes file/folder structure so I'd like to avoid having to redo anything by researching the topic beforehand. I know what you mean, that's why I wrote a Bash script that parsed my thousands old 128kbps mp3 files ID3 tags and wrote them into my new aac files. I found a way to copy jpg covers too, but I can't find that version of the script atm. Hope it helps#!/bin/bash #script per copiare le tag da un file mp3 nel file m4a con lo stesso nome #script for id3 tag cloning from mp3 file into an m4a AAC file with same basename #flapane.com 24jan10 for file in "$@" do title=$(id3v2 -l "$file" | sed -n '/^TIT2[^:]*:[[:space:]]*/s///p') artist=$(id3v2 -l "$file" | sed -n '/^TPE1[^:]*:[[:space:]]*/s///p') album=$(id3v2 -l "$file" | sed -n '/^TALB[^:]*:[[:space:]]*/s///p') year=$(id3v2 -l "$file" | sed -n '/^TYER[^:]*:[[:space:]]*/s///p') genre=$(id3v2 -l "$file" | sed -n '/^TCON[^:]*:[[:space:]]*/s///p' | awk '{print $1}' ) bandorchestra=$(id3v2 -l "$file" | sed -n '/^TPE2[^:]*:[[:space:]]*/s///p') composer=$(id3v2 -l "$file" | sed -n '/^TCOM[^:]*:[[:space:]]*/s///p') #publisher=$(id3v2 -l "$file" | sed -n '/^TPUB[^:]*:[[:space:]]*/s///p') #track=$(id3v2 -l "$file" | sed -n '/^TRCK[^:]*:[[:space:]]*/s///p') #echo $title #echo $artist #echo $album #echo $year #echo "$genre" #echo $track #echo $bandorchestra #echo $composer #echo $publisher filemp4=$(basename "$file" .mp3).m4a mp4tags \ -s "$title" \ -a "$artist" \ -A "$album" \ -y "$year" \ -g "$genre" \ -R "$bandorchestra" \ -w "$composer" \ "$filemp4" done
