sandyk Posted August 3, 2012 Share Posted August 3, 2012 At the attached link are screen grabs of the track "Song Sung Blue" using Sound Forge 9. How a Digital Audio file sounds, or a Digital Video file looks, is governed to a large extent by the Power Supply area. All that Identical Checksums gives is the possibility of REGENERATING the file to close to that of the original file. PROFILE UPDATED 13-11-2020 Link to comment
Julf Posted August 3, 2012 Share Posted August 3, 2012 Great example to illustrate what clipping and compression looks like... Link to comment
kumakuma Posted August 3, 2012 Share Posted August 3, 2012 That second screen cap is scary! Sometimes it's like someone took a knife, baby Edgy and dull and cut a six inch valley Through the middle of my skull Link to comment
Garf Posted August 3, 2012 Share Posted August 3, 2012 Correct me if I am wrong, but the second song is a live recording of Song Sung Blue? I wouldn't judge the quality of the album on this waveform plot alone, I can't imagine the SQ of a 1972 concert would be top notch. How does it sound?

The point is that the pic shows the comparison of both versions of the same song. The 16-bit one is OK, the 24-bit one is compressed and clipped. So the problem is not the 1972 recording technology... Link to comment
Garf Posted August 3, 2012 Share Posted August 3, 2012 My mistake, I thought the two songs were comparing apples to oranges. The title of one was "song sung blue.wav", the other "song sung blue livegreek th.wav". I assumed they were from the same recording, not two different formats. I was unable to pull the Imageshack full size images here at work to see the soundforge data on the recording bit depth and samples. Wow, some engineer thought turning this one up to 11 would make it sound better... Roon Rock running on a Gen 7 i5, Akasa Plao X7 fanless case.

Daren F Posted August 4, 2012 Share Posted August 4, 2012 Should anyone be interested, here's a plot of the file ripped from the 1993 MFSL (16/44.1) release. Both the remastered 24/44.1 release and the MFSL release should be from the same master source. I don't have the new HD release so I'm not able to compare the 2 files quality wise. Link to comment

sandyk Posted August 4, 2012 Author Share Posted August 4, 2012 Daren and Mitch The "original" that I compared the 24/44.1 version with was from a 1985 MCA Records release. As 1985 was the start of the "Loudness wars," it seems likely that this version had already been painted with the "Loudness Brush." The attached screen grab, which shows an obvious "clip" would seem to suggest this.

I compared the 24/44.1 vs my Original Master Recording one. I realised the sound is quite louder and the dynamic range is below 8 too. Despite that the 24 bits one does improve the sound quality, again, I can be wrong and subjective.

One and a half Posted August 4, 2012 Share Posted August 4, 2012 Let the figures speak for themselves. No wonder the HDtracks offering is seriously unlistenable, with one caveat, it should be good in the car, cause that's where I could remember these songs played.
