Can you walk looking backward in order to avoid a head-bumping against a brick wall?
ENGINEERING REPORTS
Obviously the real world should say the exact opposite. However when you speak about discoveries of the past, everything turns over. That’s why I decided to create this section named Engineering Reports, where the websurfer could find historical publications on which he could reflect and be amazed (or even become demoralized) and therefore consider that, in audio, we didn’t move to much ahead, all these past decades. Part 1: First and Less-Than-Second Order Crossovers It is well known that music mp3 files haven’t always the same quality. Everything depends on the so-called “bitrate”, or the number of bits per second. A good quality mp3 file needs a bitrate equal or higher than 128,000 bit per second, or 128 kbps. A poor quality mp3 file has a bitrate lower than 64 kbps. It could be useful to remember here that a CD quality audio file can count on 1,411 kbps, although, obviously, it’s always true that “garbage in, garbage out”. Highest quality audio files could show a monster bitrate but the quality needs to be judged according to the application: what’s good enough for portable mp3 players couldn’t be so good as far audio high-end systems are concerned. And what’s good for top HiFi systems could be redundant for car audio systems.Technical background
