Indeed is powerful. I am just too lazy to do it. 😜

Thanks. Appreciated it. Lots of reading and catch up to do.

I had the umik mic. Got it years ago. If you want, I can lend it to you

Forgotten. You need to learn REW first Download the software into your laptop. Read the REW instructions in HomeTheaterShack.com.

We first experimented with REW about 8 years ago if my memory did not fail me. It was posted in this forum by anfieldude. We did a few including my ht system back then.

I am not that level yet. Anyway will wait for the surround speaker first than only try out things

Hi all sorry if my question is out of topic. Please redirect me to the related topic if any.

I plan to buy a home karaoke sytem for my wife birthday. Any idea where and what brand to looking for?

many thanks!

NanoAVR


NanoAVR HD


DDRC88


look at its output sample rate. Only NanoAVR HD at 96kHz

That's the reason why I am holding back

kazekage_09, what is your budget for it?

Not Ultra Bookshelfs?

Oh... so, as I understand it from the info, that means the NanoAVR & NanoAVR HD calibration is not suitable for home theatre blurays as these Diracs do not support max 24bit 192KHz. I am more a home theatre person for concerts and movies and stereo hifi is secondary to me.

Thanks for your explanation.

Not yet. I got the Prime bookshelfs for a fairly good price (htkaki knows I believe). I'm not sure yet what my "end-game" would be as I'm still planning on my actual HT room.
It may be SVS ultras, it may be something else entirely. I'm intrigued by Martin Logans, I want to try JBL out and I wouldn't mind the Aperion Grand Verus line either.

Very happy with SVS though, does everything absolutely well so I'm always assured that I don't play something and it doesn't sound right. One of the best all-rounders around definitely, but it just lacks that final touch that makes them phenomenal.

It's been an upgrade coming from the KEF Q series to be honest.


I don't think no support for 24/192khz is an issue. To be honest, you're absolutely splitting hairs at that high of a sampling rate anyways. Just because a source is "supposedly" mastered at 24/192khz, it doesn't mean that it wasn't upsampled in the first place. It's a meaningless numbers game majority of the time.

just to inform you if you watch bluray concerts or any 24/192 with audyssey its will down sample to 48khz

The nanoAVR and nanoAVR HD don't use DIRAC though.

you want the full system with a player with hard drive that covers all the latest song like you have in those neway or redbox?

try this out http://www.proktv.com.my/

my dad just bought 1 and it comes with a lots of new songs

Similar to the explanation by people who says that a LOT of SACD discs and DSD64 384KHz audio files are not recorded / mastered in 64bit 384KHz when in actual fact that the source have been "upsampled". Also the same debate will also be hurled on those "supposedly 4K movies" which were NOT originally filmed in 4K resolution especially for the older movies. Even humans with a perfect hearing can only hear from 20Hz to 20KHz so if its just only about our ability to hear the sound then what's the point of even going down the route of 48KHz or anything beyond 20KHz. The same situation for ribbon drivers which can reach 60KHz frequency.

Yes, I do agree its a "meaningless numbers game" because after all, each of us perceive sound differently. In the same room with the same amps and speakers playing the same song track, this is why a person who hears the speaker sound to be too harsh with poor bass but another who listened to it can say the bass is just right and punchy, warm and not harsh.

You do have a point. Thanks for sharing your thoughts.

Well in the case of room correction, proper PEQing is like a million times more important than having support for 24/192khz. I mean, it's obvious which is more important in providing the best listening experience.

Hmmm older movies... true. Though there are plenty of movies that were shot in film that was mastered at up to 8k back in the 80s and 90s. It's only in the last decade where digital cameras were capped at 2k and needed to be upscaled to 4k for today's TVs. Only in the last 2 years where there were native 4k digital cameras, sadly.

Source is the most important in audio. If crappy source than what ever EQ or calibration don't even have to consider

I believe that you are an expert in home theatre and you do mean well. Thanks. Appreciated it.

I have just found out that there are factual reasons why frequencies above 48KHz are not used as stated in the link below...

Mmm... where did I mention anything about Audyssey ability to do 24bit/192KHz because I DO know that Audyssey down samples to 48KHz. When I stated that bluray audio max to 24bit/192KHz was because I wondered why Dirac did not do 192KHz to achieve calibration closer to bluray 24bit 192KHz audio. My thoughts were... "if Dirac can do 192KHz, then it would be much better than Audyssey". Obviously I know now, the reasons for using max 48KHz have clearly been explained by Chris Kyriakakis from the link above. Its not about Audyssey doing 192KHz which I do know it does not.

I am new to this so forgive my stupidity in whatever questions I posted here as I have just started learning the "art" of using "devices" to correct room acoustics. As I continue to explore and research more, I do find it very very interesting indeed.

Obviously la bro. That applies to low quality sources that still uses VCD sampling rates.

But we're talking about high quality sources here from BD at least (I thought it's presumed already?), at above 24/48khz there isn't going to be a very significant difference beyond this sampling rate. As I said, we're pretty much splitting hairs after this.

So true, so true. Room acoustics do play a very important role and proper PEQing is paramount. It does not mean anything for 24bit/192KHz if the microphone cannot even capture sound pressure above 24-30 kHz as explained by Chris Kyriakakis. Refer to link below...

Thanks.

I also agree.

From the discussion standpoint here on audio calibration for the room acoustics, it is assumed that we use a high quality audio source for calibration. Yup, a high quality audio source track is a necessity for calibration.
