3D sound with my own XTC

Rate this topic

Recommended Posts

After 9 years of struggle with commercial XTCs, I decided to make my own that can play studio recordings as good as the full orchestra music. Took me about two months and here is the final product's sample. 

 

Recorded with 17cm spaced microphone from my listening seat. Only two speakers used. Recorded with Zoom H1 and Roland CS10EM microphone. Format of recording is 16/44.1. All tracks were played via JRiver through Reaper. All tracks were 16 bit 44.1kHz format except for Lux Aurumque which was MP3 downloaded from CDBaby. Just a short excerpt of each. 

 

1) Norah Jones -I got to see you again.

2)Famous Blue Rain Coat

3) Money - Pink Floyd

4) Lux Aurumque

5) Black Magic Woman

Would you elaborate more about 17 cm microphone placement? 21 cm seem to be much more appropriate. Also, what kind of seat you used?

 

Just a standard 3 seaters from ikea. The 17 and 21cm is based on pinna to pinna measurement. There is no correct answer here. I think 17 is more correct as our actual hearing mechanism is deep inside. 

 

BTW, the last one was a direct iphone SE video. No spaced microphone.

All Ikea related would not qualify as a high-end.

I can understand you they add just about anything to it to make it cheaper.

BTW could you PM me the details of the method you used to synthesize it by yourself.? :)

I don’t understand. What is there to make them any cheaper when most of the product are either free or as low as $10. Perhaps, BACCH is the most expensive one at $50000 for their high end version which is now the gold standard. 

 

If you need the algorithm, please let me know.

I was joking the abbreviation XTC is sometimes used for ecstasy (drug).

Oh.... sorry to disappoint you for not getting it. ;) 

No need to apologize, if I remember correctly my jokes have been understood by others 3 or 4 times in the last 30 years, I got used to that ;) (I'm still working hard to make my sense of humor a little less hermetic)

yes, most here are too old to get that joke

 

try a FLOMAX JOKE...


"The overwhelming majority [of audiophiles] have very little knowledge, if any, about the most basic principles and operating characteristics of audio equipment. They often base their purchasing decisions on hearsay, and the preaching of media sages. Unfortunately, because of commercial considerations, much information is rooted in increasing revenue, not in assisting the audiophile. It seems as if the only requirements for becoming an "authority" in the world of audio is a keyboard."

I'm not a rave generation either, I just live in the Netherlands.

Made further improvement to the crosstalk cancellation. I can now make the bee or the haircut sound at the ears. Also it looks like one setting can be applied for different genres. The tonal balance is correct.

 

Here is a video of 15 tracks excerpts which consist of tracks for vocals and some percussion. Also included 2L classical recordings. The Money and Window track should still able to produce the effect near the ears even on YouTube. I have been using the same tracks last two or three years for reference. Now time to review 100 over audio samples to find out which one sound the best. Lux Aurumque is also included as I find the Stereophile video of the same track is an interesting case study. That sounds almost original something which I never managed to record of the many high end stereo system that I could access. Waiting for this year's AV show and see if I can the same sound as in the Stereophile recording with stereo setup. 

 

The audio was captured using  omnidirectional microphones. This may not produce the exact drums attack but it can reveal much about the room acoustics. Sometimes, directional microphones may sound better with video but that not what you actually hear in the room. Hope to see more than 4 viewers for this video. :)

Now time to select the setting. These are my current 8 best settings among 100 over different implementation. Each of them has their own strength and weakness.  Out of these eight I have two which is accurate for my preference. Unfortunately, others in my family have their own preference among these 8 settings. Thankfully with Reaper it is just a click of the mouse to choose the preferred one. No need to change cables, amps or speakers to hear the difference in soundstage or details. This is not high end for audiophiles. :)
