Re: Modern Day FMs

^that doesn't even look like an fm seems to be some faint line where the carrier should be and a bit of an 'edge' where the cutoff shold be very strange...

Re: Modern Day FMs

[quote=Five]looks like the dehissed version is from a different source, as it has more frequency response in the highs

That's the strange thing. According to the lineage and to the words of the uploader it is the same source. I included a 2 sec SA (of the old FM) as it looks like the one I provided doesn't work. But I guess it doesn't change much. Clearly lower response above 16 khz.

Oh well. Same problem as before. But I used a different pic.

From the info:

FM - tape - editing ....- cue sheet with EAC - tracks done with cuesplitter - flac8 - md5 - you (no artwork, not cd/r sourced - taper me - )

Den Haag Statenhal 1997-02-21 - approx 49 min.
10 Tracks, last "track" is the mods voice and can be removed

Hamburg Markthalle 1997-02-22 - approx 53 min.
11 Tracks, last song faded out


I have the Hamburg part only. No announcer on that one. So can't prove correctness of information. But would be strange if it was wrong. Still, I always believe that you are right, Five.

Re: Modern Day FMs

Since we're on the topic of FMs...

I've got a show with his lineage:
Digital Radio (over Digital TV Receiver) - Harddisk Recorder (LPCM Mode) - Burn to DVD - Rip Audio to Harddisk with SmartRipper - Normalization to 96%, Fade-In at the Beginning and Fade-Out at the end - Convert from 48kHz to 44.1 kHz

Does the spectral show a normal FM, or its MP3 encoding lossy?

It's MP2 192 kbps, and of course lossy. You preserve a bit more from the original signal if you don't convert it to WAV but burn it as a fake DVD - blank (black) screen with audio. Such DVD may store almost 20 hours of music in MP2 format.
