Deep Bass

[John in MA]

If they ever get that organ fixed I will have to go see it. Is it in the Atlantic city that is in NJ?

Also, Toccata and Fugue is my favorite song. So much so that i actually memorized the Toccata and can play it. (although not well)

Correct, it's in what they currently call "Boardwalk Hall." It's a mammoth bomber-hangar-like convention center located literally on the beach. How's this for an organ concert?

To make the task simple, I'll use Audacity, a free software program capable of rudimentary frequency analysis, sampling a 15-20 second window using the simpler method. The data and graph will be done with the Hanning window setting, which will reduce the output from the actual levels, but make the structure of the signal more evident and interesting. So, bear in mind that the graphs are showing the deeper frequencies as much reduced compared to how they actually are in the recording.

I'm sorry, but I'm not familiar with this software. I gather you feed a line level signal into your sound card, which then digitizes it to allow the analysis you show?

If so, how important is it to have a really good sound card? One might expect that not all sound cards have a linear frequency response, I suppose...

I assume he's already using a digital source (i.e., CD), and simply ripping the files to the HD and using the software to pick it apart.

I shall now proceed to raise a glass of adult beverage in your honor for using that instrument as a reference. I thought I was the only guy on AK who is an ACCHO fan. My life will be improved greatly if they ever that thing fully working again and release some hi-fi modern recordings.

Thanks, but I'm afraid that I'm a fairly ignorant fan. All I know of that organ comes from their somewhat sparse website and the little I know of organs in general. The engineering behind these behemoths is just astounding especially when one thinks of how complex some of the organs were for their time -- the space shuttles of the 18th centuries.

x 25, sorry about taking your favorite song. T&F has been one of my favorites of mine since I was a kid and regained that title when I heard it again on a good system with bass extension. I most definitely have to hear it on a real organ some day. Or build such an organ. Let's see, if I get a large enough yard and bury 64' of 4' culvert pipe in it... :scratch2:

If I can venture to guess, your Telarc Chiller CD is from the mid-'80s? I've noticed that the earlier Telarc CDs tend to have a sharp rise in output below ~4Hz compared to their later pressings. I suppose their equipment at the time had some noise issues down there, but wasn't yet capable of monitoring that low in frequency.

I'm sorry, but I'm not familiar with this software. I gather you feed a line level signal into your sound card, which then digitizes it to allow the analysis you show?

If so, how important is it to have a really good sound card? One might expect that not all sound cards have a linear frequency response, I suppose...

Audacity is freeware that I'm using to analyze the .wav files of tracks that I rip accurately with EAC thus keeping it in the digital domain for accuracy. While my CD player is spec'd as being flat to 2Hz, my sound card is far from linear down there. So, it'd be difficult to see the same signal in analog analysis that my stereo sees and tries to reproduce as far down as the woofers go (amps are direct coupled, so no bottom end roll off there).

I encountered a couple more during my random play music listening last night. Granted, the notes are synthesized, but unless one has been stuck in a time warp or has exceedingly narrow music taste involving old or highly specialized recordings, the majority of music will contain such synth instruments.
