View Full Version : Audio ripped from video (avi) is lossy,
right?  Damage, Inc. 2006-05-03, 11:39 AM I was going to use my
Canon Powershot SD450 to take some pictures of the Mick Thomson
guitar clinic I went to, but there were no pictures allowed so I
figured I just record the thing. It has a video option, so I
just left it recording with the mic up (and the lens not aimed
at anything really) so I could use the audio from the blank
video. It records into .avi, so I ripped the audio from that
(using Virtual Dub) without changing any attributes, and I was
left with an 8 bit mono wav. I did an freq analysis on it (after
chaning it to 16 bit) and you could think its lossless because
nothing drops off, but thats just how it was ripped - basically
like a transcode, right? The camera compressed it for the video
when recording, so my actual source recording is lossy, correct?
I can provide a sample if needed but I don't think its really
neccessary. Thanks.  2006-05-03, 01:06 PM At 8 bits it's not CD
quality. If it
