Audio ripped from video (avi) is lossy, right?
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.
