This is the spectral view image of the Finnish Broadcast Company's (YLE) cable FM broadcast of Gnarls Barkley's gig at the Provinssirock Festival 2006.

According to Cyber College: "Since both ends of the 20-20,000 Hz range represent rather extreme limits, the more common range used for FM radio and TV is from 50 to 15,000 Hz. (AM radio falls significantly short of this range.)" The frequency response of this cable FM recording of mine is possibly up from 20 Hz (not really reaching down that low?) and cutting off around app. 16,000 Hz - the app. 16,000 Hz cut-off being quite usual for the FM radio broadcasts as mentioned above by Cyber College. The carrier signal is around app. 19,000 Hz or even a bit higher.

Am I on the right track? This cable FM recording of mine isn't lossy?

the 19kHz is the stereo pilot tone. Tells the receiver to build stereo channels from the composite signal. that other crap is probably info the cable company spikes on to get data from place to place.. could be guide data chunks, etc

As far as digital compression goes, can you repost it in about a 3-4 second slice?

This is quite much all I can say about it right now to your reply: all the original information of the gig recorded. No cable FM digital involved. It's all cable FM analog.

16 - Radio X3M Live jingle

Notes:
I fixed few clicks, a small flaw at 2:xx.xxx on "Just A Little Thought", did the track slitting, a little volume tweaking and fade in/out in the beginning/end of the show. Flac files are aligned on sector boundaries. I let the Radio X3M Live program jingles be in the beginning and the end, because they continue slightly right into the music and therefore there wasn't much room for cutting them decently off.

According to the netsite of the Radio X3M this Gnarls Barkley's gig ought to be songwisely complete.

Have fun.

OK.
Here's app. 10 sec. Gnarls Barkley sample for you.

Should it be longer?

Possibly not. I've seen the same stuff when this household was receiving them fine tune tunes flying around in the air by the antenna.

I'm just curious enough to ask you, how low do you think this recording is reaching?

you'll have to do a frequency analysis with a logarithmic scale to determine that.

Oh yeah? How about you fix it? A logarithmic scale? Are you kidding me? I've just already given you the spectral view and the sound sample as you requested? And now you want some logarithmic scale? What's next?

Ps. Please. Could you hand this thing over to Five. He seems to know some a shit about something.

How low it goes doesn't affect whether you can seed it or not. They find out if it is lossy by looking at the high frequencies. If they don't see any compression artifacts or evidence in the highs, go ahead and seed it.

the 10 sec sample you posted won't decode [unparseable stream]

Yup. I was only curious how low it goes. Of course to get a right answer is straight from the horse's mouth, in this case the Finnish Broadcast Company's technical support.

It takes about 5 seconds with the software you are using.

ok, I've helped you for the last time (at your request). The frequency range of the recording has very little to do with determining lossy compression. It's only used as an initial indicator - and certainly not the low end of the spectrum.

You ASKED about the bottom end of the range, so I told you how to see it. You have the correct tools, just not the correct attitude. Feel free to continue to not know.

You ASKED to post the spectrum so we could give you an opinion about it. The time scale you posted isn't optimal for determining that, so I asked you for a 3 second slice - which you have yet to post.

Hmmm...
Interesting. I was asked for a 3-4 second slice. I gave you 10 sec. slice. And that won't decode? What might be the reason for that? And how to go on further if you can't say straight from the spectral view image if it's lossy or not?

yes, the 10 sec flac file you posted would not decode for me [i'm using xACT v1.62 - getting the error "unparseable stream"]...but that issue aside

from what i can see, this **seems** to be an analogue FM recording, which according to our standards here at TTD would be acceptable to torrent...however, we're talking about an artist that uses samples for his beats, which can cause different results compared to a typical recording of acoustic or "traditional" instruments...

but i don't have as much experience when it comes to european FM feeds, so if i were you i would wait to get a more definitive answer from a few of the ABT mods [jameskg, dcbullet, Five] or one of the other resident experts such as ssamadhi

just a fwiw, but we [TTD Staff] don't get paid for this, have busy lives outside of the internet, etc -- so you might want to be a bit more patient when asking for opinions/help, otherwise you come off as an arrogant ass...to properly analyze a SA for lossy/lossless purposes, it helps to be able to see the sample in a few different time lengths, which is why jameskg was asking for a different sample length [and Five would've asked for the same thing ;) ]...again, i just say this as a fwiw, you can say/act however you want really, just don't be surprised if no one helps you

Yup.
I actually might do know why the sound sample I sent you didn't decode/open: possibly because of I closed the upload window before the upload was "ready".

Yup. I do understand the rest of your statements about conduct etc. Never, ever been in this kind of a situation before, though I've been a member of various sites like TTD before. But that discussion don't really belong right here in this forum.

BTW: Why did you pull off Misfits? In just curious. That's all.
