That would be of great help. Thanks. Just send me half a min. of Kati Patang song 'Yeh sham mastani' Because I have audio cd of it.

If you mean by 'revival' series I have heard them. they sound clean and HF accentuated. But not natural. Personally I am looking for differences in the original content as much as possible. That means not altering or modifying original source.

Thanks to bringing it to notice. what I did was I opened both Vinyl and Audio cd file. cut the similar section of one minute of both files discarding remaining portion. Screen grabbed the top channel and pasted it on another screen grab. What you see as low frequency cutoff is just I cropped the image too close. I will look in to the scale. Pardon for doing job in hurry. Not my style. I will repost. But I hope basic essence of evaluating remains somewhat relevant.
Regards
Edit : Some part corrected.
