Frequency spectrums of recorded music

Unread post by Lindsayt »

I've started a new thread on this as a spin off from the pfm thread from Elsewhere on the Web.

I still say that there is nothing on Solitude Standing that goes anywhere near the low in the bass, though. I don't have a copy myself since it is not my scene.
A CD of 'Solitude Standing' arrived this week, gave it a listen Thursday night and zzzzzzzzzzzz... Oops sorry almost dozed off but I managed to make it through. :mrgreen: Have to say that I don't think there is anything on that album that even remotely approaches 20 Hz. I don't know what was being measured but I'm now pretty confident that whatever it is, it is not music signal.
Have you analysed the frequency spectrum with something like Audacity?

Would you care to explain to me exactly what it is that Audacity is finding that is there on the musical part of Solitude Standing that isn't there on the run in groove?
It's also there on Dead Can Dance Oman.
It's there in greater quantity on Solitude Standing and Oman than on Wishbone Ash's You See Red and Talking Heads And She Was.

Have you tried listening to Solitude Standing on 2 systems: one that starts rolling off at 50 to 60 hz and one that starts rolling off at 20 to 22 hz to determine if there's any difference in the experience, inparticular in the lower bass?


Just because it sounds like there's not a lot of 20 to 40 hz content on Solitude Standing on your system to your ears, doesn't mean to say there isn't.

According to this, the threshold of audibility at 20 hz is 75 dbs. That's pretty loud.
Turn it right up to 90 dbs and we should be able to hear it, if it's there.

And here's the frequency spectrum for a few seconds of the run in groove on this dirty, well used copy of Solitude Standing.

Please note the very different vertical scale and slightly different horizontal scale.

This is the frequency spectrum for the first minute or so of Wishbone Ash's You See Red. 12" single.

Please note the slightly different horizontal and vertical scales on this graph, when compared to Solitude Standing.

Edit: and here's the frequency spectrum for about 1 second of the run in groove of You See Red. This was a dirty 2nd hand copy. It sounds pretty hissy and clicky. A good clean may well make the background on this quieter.

Please note the very different vertical scale.
