Every now and then I get notices for sample tracks of some high resolution audio. I've posted information about both of these sources before, so some of you may have received the same offers.
The first is Linn Records. On their website they have an article titled, "What is a Studio Master?" It explains how analog recordings on vinyl or magnetic tape sounded better than CDs because of the analog to digital process that chopped up the perfect waveform into little bits. They oversimplify things and fail to mention the problems when reproducing sound with a needle vibrating inside the groove of a rotating vinyl platter. Anyhow, I don't want to start a big debate over analog vs. digital or vinyl vs. optical disc. I have a pretty good Linn Sondek LP12 turntable that I haven't used for years. I prefer the quality and convenience of playing digital files from my media server to several computer systems, which are connected to my stereo and home theater gear. They go on to tell us that their Studio Master files are much higher resolution than CDs and sound as good as analogue. I would say they sound better than what you will hear from vinyl or magnetic tape. At the end of the article they provide a link to some sample files. I encourage you to download these and have a listen. Obviously, you'll need equipment capable of handling these files. BTW, the article mentions that Studio Master files are encoded at 24-bit or higher and up to 192 KHz. These samples are actually 24-bit/88KHz.
The other source for high resolution audio samples is 2L, the Norwegian music label. They have a few tracks in a variety of file formats and resolutions. They also let you choose both stereo and surround versions.
