Compression artifacts

Started by HyeeWang May 4, 2009
Compression artifacts in compressed audio typically show up as
ringing, pre-echo, drop-outs, warbling,
metallic ringing, an underwater feeling, hissing, or "graininess".

How and when the artifacts above occured? Where can i get the
appropriate speech samples to taste the effect?
More,anyone can explain how the artifacts come into being in detail?

Any coments would be appreciated.

Regards

I second that -- long experience on USENET teaches that the only way to deal with bad behavior is to _maybe_ say something to someone once, then if they don't get the message then _ignore_ them, no matter how hard it may be. Otherwise you just get sucked into becoming part of the problem, instead of part of the solution. If you like USENET well enough to put up with the weirdos, consider getting a real newsreader that lets you filter by the originator's name (I use Pan and Thunderbird). Then just filter out any content from them, and let them gnash their teeth and foam at the mouth all they want, alone. -- Tim Wescott Wescott Design Services http://www.wescottdesign.com Do you need to implement control loops in software?
