I Lead You Towards Glorious Times is live?

I did not know that.

Clearly that had an impact on the sound quality.

The Garbage excerpt: OMFG, is that really on the CD like that? Even when zooming in on the waveform in my audio editor, I can hardly see any dynamic structure in the waveform. It looks (and sounds) like clipped pink noise.

This is the worst example I have seen so far. What are we doing to our music crying.gif

Thanks for sharing!

Chris

"I Lead You Towards Glorious Times" - now i get it.. that's the NOISE music genre, which is now taking over metal:( - actually..every music genre has been merged into the NOISE GENRE.

WHAT TO SAY? -> WTF OMFG

also.. i'd like to add that in comparison to this: metallica's death magnetic was flawless in terms of audio quality

"Merzbow" replay gain -21.04 dB
Wow - I didn't think such a ReplayGain value was possible with PCM!!! wink.gif

Cheers,

So far "I Lead You Towards Glorious Times (live)" has been the loudest commercially released music track that I have seen. It is pretty close to white noise (not all Merzbow tracks are this extreme). The FLAC -8 bitrate of the sample is 1397 kbps.

Here's the screenshot that I posted in the linked thread:

The encoding settings
FLAC: -8
M4A: QT --tvbr 62 --highest
MP4: Nero -q 0.41
MP3: Lame -V5

It is also interesting to see the peak values of the lossy encodings of it. LAME produces a peak value of 2.73. Apparently the VBR encoders don't even try to achieve a more transparent result by radically increasing the bitrate. Perhaps some kind of sanity check kicks in.
