Compressed recordings
« on: 18 Feb 2008, 03:34 am »
Part of my physics class were at GR-Research Thursday and got an earful of a very realistic sounding AV-0 style project that Danny Richie had  put together and the very nice 0-3's.  It is always a kick to watch these kids when they hear a nice system for the first time.  My favorite student comment  came after listening to a cut by Vienna Tang.  "Wow, it sounded like a piano was in front of me!"  My other favorite comment came after they were listening to something that one of them had brought with them that was basically unlistenable due to the amount of compression.  The kid that brought it said "That really sounds like crap."   :D It was a good day as an educator!

The group arrived back at school eager to get started on their speaker projects.  Teaching is a whole lot of fun on the good days!

Hey!

   Professor Clark, don't forget to explain to them about the over use of compression these days and how this affect the sound of the music their love. :D And let them go out and spread the words :wink:

Take care,

  That's too bad to see kids totally miss the point like that.  If they were a bit more on the ball they'd realize that if recording B is louder than recording A then recording B IS better.  Like, DUH!  I thought that was common knowledge!

I certainly hope kids aren't making music choices based upon such frivilous criteria like taste.  The peak to average ratio is all that you need to know.  If you get a record in 2008 that's pretty loud that's great, go ahead and listen to it all you want; but it's likely than in 2009 something will come along that's louder.  You must then dispose of the 2008 record and listen only to the louder selection.  It's the only logical choice. 

Every day recording engineers are working hard to get as many samples as close to 0db as possible, and it's not easy.  Sure, you can talk about far-off utopian visions of listening to pure direct current, but that's still just science fiction.  Right now we have to be satisfied with the volume we are able to get with the tools at our disposal.  Kids today should be glad that they don't have to put up with the vile dynamics and textural shading of the early days of recording.  In the bad old days a guy could hit a snare drum too loud and it might startle you.  Do you want to listen to such frightening sounds?  I certainly don't!  Now we have the technology to make everything even and straight, the way it's supposed to be.  I just hope children aren't being needlessly lured into the sordid world of quality sound when there's perfectly good square and sawtooth waveforms to be listened to.
