Comms theory - Stereo
I've been converting my music to MP3 since before the ipod, and was studying communications theory at that time. I have had some pretty good setups to listen on. Even on the most low quality equipment I found 128k noticably poor. For background music it is ok but not for actively listening to. I have found VBR to be the best compromise, as some parts of a track have less treble detail (where disk space can be saved), and some parts of a track have loads of treble detail competing with each other. Will I re-rip my music to FLAC?..maybe some of the well-mastered good quality albums. However I also have some albums in DTS surround format, and for me that is the future..not stereo. Each speaker with a channel, with an appropriate bit rate for that channel. The sub would need the least, the mid-ranges would only need to deal with the mid-range frequencies so there would be less interference and harmonics to worry about, and the tweeters would be where the directional information comes from, and again, mastered so that they only get the info they need. I am not suggesting dropping higher frequencies at the mastering stage on an instrument by instrument level, but having a fully integrated mastering model where the input was all original sources, and the output was 7.1 surround with each of the 7 channels intended for a speaker with certain characteristics. No point in the sub in my car getting anything above, say 300Hz, and no need for my tweeters to have to worry about anything below say 1KHz? If the tweeters then only got the info they needed, then VBR could allow for big savings despite keeping the resolution for higher frequencies high because higher frequency detail isn't needed 100% of the time, but when it is needed it is important.
