Devendra Banhart - Live @ KCRW; Lossy Source? (Freq. screencap inside)
So, got this Devendra Banhart @ KCRW's "Morning Becomes Eclectic" in a postal trade the other day, and since it had quite a large ? in the lineage (Studio > FM Broadcast > ? > FLAC), I decided I'd try my first frequency analysis to see if it was lossy source (being that the webcast is the usual source for KCRW's without complete lineage) Soon discoverd that FM broadcasts and mp3 sources have a tendency to look similar in a freq.anal., so I thought I'd run it by the collective intelligence of TTD. So, is this lossy or not? The neat "haircut" right at 16K makes me tend to believe that it is, but I'm hoping against hope that's the FM compression.
Thanks! No members have liked this post.

Re: Devendra Banhart - Live @ KCRW; Lossy Source? (Freq. screencap inside)
whats up rabble
i'd say the 16k line is more typical of FM than it is webcast...most of the webcast-captured stuff i've run across cuts out around 18k... Five can tell ya more...you shuld check the new Spotting Lossy sources forum: http://www.thetradersden.org/forums/...splay.php?f=47 i'll get one of the mods to move this over there...you should get more replies that way No members have liked this post.

Re: Devendra Banhart - Live @ KCRW; Lossy Source? (Freq. screencap inside)
hey rabble
from what I can see so far it could go either way if you could post a SA of a full song and another zoomed on about 2 seconds that would be great. and FA too if possible. good if you can keep the little time numbers at the bottom, too.

Ok, attached are a spectral analysis of the full song, spectral analysis zoomed in 2 sec, and a frequency analysis.

Re: Devendra Banhart - Live @ KCRW; Lossy Source? (Freq. screencap inside)
yeah, I'd call that mp3.
the FA isn't displaying correctly. CEP has a bug where you have to move the cursor to sort of wake up the Frequency Analysis display. try opening the file again, opening the FA window then clicking around the cursor on the wave display a few times. It would be cool if you could post a pic of that.

I couldn't get it to change the display by clicking around, but I did adjust HOW it was displaying, maybe this is what you were talking about. I've got both linear and non-linear views attached... Gimme some good news, five!! No members have liked this post.

Could you please do another sa shot of two seconds and save it in *.gif format? this would be more detailed.
Is this an accoustical track. Does the artist speak much? I donīt know Devendra Banhart. No members have liked this post.

Actually, there's no need for me to post a sound sample, you can listen to a webcast of this show here:
http://www.kcrw.com/cgi-bin/db/kcrw....mplt_type=show The SA & FAs that I have posted are from track 3. No members have liked this post.

Re: Devendra Banhart - Live @ KCRW; Lossy Source? (Freq. screencap inside)
I believe the show in question in mp3-sourced. when you get a chance perhaps you could post another FA, you have to click around to sort of wake it up. The one above doesn't look accurate to the SA.

(I clicked around like a bastard on this thing, couldn't get it to change a bit. I did, however, uncheck "Linear View", I hope that was what you were looking for.) Thanks again for the help, guys! No members have liked this post.
