Is this mp3 sourced?

[Five]

That jives with what I've seen so far, anyways.

btw I was referring to the "MP3 file with a similar spectrogram profile" that Dr. Bob was using as an example. A little off-topic, I know.

K so many people going off on tangents it's hard to keep up.

Someone asked if his lossless files are MP3 sourced, based on spectral and frequency analysis. I just tried to help, I said I believe the screen caps are from a lossy-sourced file (MD use lossy compression) but I added that sometines spectral and frequency analysis are not conclusive, and I included some caps from a MP3 file, that doesn't have the usual cut on the highs. That's all. I can't see how I'm "going off on tangents"...

Yes it's a 320kbps file (I'm not sure about the encoder). Sometimes MP3 don't look too much like MP3.

hmm... at the higher bitrates, it sure it more difficult to tell. This segment you've posted the pic of has hardly any audio in it at all. With lossy sources I can always seem to find the distinctive "blocks" in the SA when I zoom in, perhaps thanks in part to some settings I changed as per ssamadhi97's advice way back when. I'll post those recommended settings for CEP/Audition up here once I find them (or perhaps ssamadhi97 will drop by and post them before that).

Anyhow, it seems that every one of these "is this mp3" threads goes off into the discussion of "it's hard to tell anything for certain" which is a fact, but this doesn't stop us from mining the data that is available.

Now with the case in point, I have procured a ten second sample.

SA of the full 10 seconds:

What we can tell so far is that this is not cbr mp3-sourced, since the "black" at the top doesn't appear as a straight line.

What can also be gathered is that this is a lossy source of some kind, due to the appearance of "blocks" in the closeups.

[Five]

also, the FA looks great, except when you hover over the last section of this sample a steep drop-off just below 13kHz can be seen:

This file has the "lego" look of an MD source. It also slightly resembles VBR mp3, but all the VBR mp3-sourced stuff I've analyzed has had smaller "blocks" visible where there's transients.

So, from my best analysis & gut feeling, I'd call this MD-sourced (like Rider said).

This portion particularly resembles another MD-sourced show I have on my drive:

[Five]

...and last time I checked, shows recorded on MD are acceptable to be seeded at TTD (somebody correct me if I'm wrong)

MD makes sense because on www.SPFC.org the hideout shows were recorded with an MD. But what doesn't make sense still is how this got out. Quinto never released flacs, and it was always in MP3 before.

One Frank said he was going to put it out if he coudl find the masters. Two if you think Frank has never given this stuff to other people you are crazy.

Yeah I know he said he would put up the masters, but according to what he said in the hub, he didn't.

From the hub:

[09:18 PM] Quinto> i haven't gotten around to make a lossless version of hideout comp 2 yet
[09:18 PM] Quinto> i haven't had time. i've been soooooo busy
[09:19 PM] Quinto> so i don't know where the lossless version thats on the hub is from. but it's not from me.
[09:19 PM] Quinto> and i didn't give the flacs to anybody

The < in front of his username had to be taken out, because when they were in it didn't appear to show the username

[Five]

Somebody got the mp3 version of this show? A direct comparison could help at this point

[Punkishlyevil]

Yeah I got it. Should I email you a clip of an mp3 or the whole song?

[Five]

If you could email me the track that the last clip came from that would be cool.

As of right now I am going to get Hideout II unshared from the hub until a definitive answer can be given. I've looked at some of this through WaveLab and the unpacked FLAC version and the MP3 version are very, very similar.

Also, since Frank has come out and said he didn't release this in lossless, the current "lossless" version on the hub is more than likely converted MP3 files.
