im not quite sure how 'blocky' a lossy format is allowed to be, without beieng a transcode.
thanks.

A Styx fan, huh?

In all seriousness though, its (impossible?) to tell. Those "blocks" you see are probably the beat, though, and its clearly been sharply attenuated at 16kHz (is this an MP3?).

styx? i dont get it smile.gif

Its a 192 CBR FhG coded MP3

a better view mabye.

If you enjoy looking at your music rather than listening to it, you should consider using a lossless format instead, and rip your own CD's.

wow - that was useless

It's going to be almost impossible to tell anything from that spectrograph unless you have the original uncompressed file to compare it to. Even then, comparing graphs of any kind when looking at lossless versus lossy only gives you part of the story anyway.

Simple question. Does it sound OK to you? smile.gif

Cheers, Slipstreem. cool.gif

thank you. i was under the impression that you could spot a transcode from the lossy file alone.

I was making a joke - like us HA.org readers are so advanced we can spot the artist from a spectral graph, when in fact that graph only tells me the frequency cut off, and the tempo.

You can't - but a very grainy spectrum might point to a transcode. It doesn't look very grainy though.... so from my very first guess I would say: no transcode. But this "no" is far from being safe....

Quite interesting is the lowpass at 16kHz with occasional blocks >16kHz. I know that the FhG-encoder seems to have a "builtin"-lowpass but this blocky appearance of the parts >16kHz looks as if they implemented something like the "lame -Y "switch for their CBR encodings....

It is OGG Vorbis file @ 400 kbps. Of course it was transcoded from MP3 (about 192...256kbps or Lame V0...V2). (Well, I suppose so).

Uhm, just curiosity: How'd you get these graphs from? Is it from Cool Edit audio editing program?

Yes. Spectral view.
