We disagree about Vienna a bit more than I'm used to disagreeing with you -- partly with regard to her success potential, given that her albums are apparently #2 and #3 on Amazon this week. Either way, it sounds from her blog as though her career is moving forward at roughly the pace she'd prefer, which is great to see in that it seems to happen so rarely for emerging artists. Question for all: I see that glenn also just got around to _Tales of a Librarian_, which is cool because I always enjoy reading his thoughts on Tori. They brought to mind a question that I'd wondered about when I first heard that album, and I figured I'd toss it out there: does anyone know if it's possible to perform some sort of operation in a sound editor which will extract/highlight just the differences between two versions of the same song?

Thanks Bill! Now I just have to borrow a copy of Aja. That would probably be easier then finding my records and unpacking my record player. I actually have it as an LP and haven't listened to it in probably a decade. I decided to stick purely to Odyssey songs and ditched the Icarus tunes. None of them were compelling enough to make me extend the theme. Thanks! neal np: Po' Girl - Po' Girl (a Be Good Tanyas offshoot that I think is even better then the Tanyas. Just saw them at Folk Alliance, and they were better then the Tanyas live too. Allison Russell is an amazing singer and a compelling presence. Plus, she plays clarinet! Highly recommended. (I think they are in Portland right now, so pay attention!) ------------------------------ Date: Thu, 11 Mar 2004 21:26:44 -0500 From: "Foghorn J.

Interesting question... kind of like how you can take two images in Photoshop, layer them, then subtract one from the other and view the differences? Incidentally, this is a simplification of how digital image watermarking works. I played around with Adobe Audition (successor to Cool Edit/Pro) and couldn't find a simple parallel to the imaging analogy. However, I did find something that looks promising. As a test, I have this CD from the band Blotto, an upstate New York comedy band from the '80s. On that CD there is a normal version and a 'karaoke' version of their hit "(I Wanna Be A) Lifeguard". I loaded up the vocal-free version and set the entire track as a noise sample for purposes of noise reduction. Then I loaded up the normal version and ran the noise reduction. What was left was essentially the vocals and little else. A little squeaky to listen to, but definitely recognizable. ------------------------------ Date: Thu, 11 Mar 2004 22:44:57 -0600 From: Hooplessly Unfroody Subject: RE: Remastering question (Re: some Ecto reviews) At 09:26 PM 3/11/2004 -0500, Fog Horned: >> does anyone know if it's possible to perform some sort of operation in a >> sound editor which will extract/highlight just the differences between >> two versions of the same song? >I loaded up the vocal-free version and set the entire track as a >noise sample for purposes of noise reduction.

Actually, most decent software should be able to do it. What you want to do is invert one of the waveforms, then add it to the other. You can test it by working on 2 copies of the same file - the inverted waveform will cancel out the original, leaving silence. For a fun project, take a file, compress it to mp3/ogg/lossy compression of your choice at a couple of different rates, uncompress the files back to waves, invert the original and add it to each of the reconstituted lossy files. What you hear is what was determined to be "inaudible" and lost in the compression. bob ------------------------------ End of ecto-digest V10 #71 **************************
