Standing waves are frequency related!

Hi Peter,

Just a small teasing  with your future speakers.

You wrote:
When things sound bad/wrong etc. etc., the very first thing "we" learned is : it will be the room. It is our very first huge excuse.
----------------

You will see the efforts you and BertD have to manage to  get the right sound from your speakers in your room.
And one request: Please do not shut down your server during the  first extended listening sessions with the new horns.

Joachim

Yes, your room makes me wonder! The sound is phantastic!!!
The only explanation I have, is the enormous kitchen area with all the "filled glasses" on the back side of the room.

Joachim

Hi Frank and Peter,

let us answer the question of the original source of the music! The music is recorded in a studio or opera etc.

A picture of a new concert hall in Copenhagen see:
http://admin.medite-europe.com/imagebank/59.jpg

The sound in the studio or concert hall must sound right at first,
and then the sound engineers are mixing the record in their studio,
and in their studio the sound must be right too.
We hear the result of the recording engineers at our speaker drivers via our frontend.

Let us assume our listening room is ultra modern and all walls around are glas walls, no curtains around. Then I promise ............... .

Impossible due to different echoes/reflections/reverberation times!

You both are discussing and we are waiting for XXH running with W8.  (This is a joke)

A Little bit late, but

This notes by Peter are leading us into a blind alley and we do not get the best out of our system, to listen to pure music.

In general we need a basis, a reference configuration of our listening room with the speakers.   
We need a balance with
-   the direct sound from the loudspeakers
-   the discrete early reflections from the floor, ceiling and side walls
-   and the reverberation time
etc.,etc.

Nice to read is the homepage of:
http://www.soundfountain.com/amb/speaker.html
 and amongst many other literature
“The complete Guide to High –End Audio” by Robert Harley, chapter 4

With this reference configuration of our SYSTEM (room and speakers) we are in a position to compare ……. , ONLY THEN we hear the pure sound of the music in OUR room!!!
The room must sound right at first, and so I can hear the differences of any audio software and components etc.

The basis of our hobby is physics and there are tons of literature available how to built the perfect room (Opera houses, studios etc.) for music performances and replay.

The XXH software is creating the BEST SQ in your room only, and no other room will be on par with your SQ!
You are measuring and adjusting the software to avoid your room abnormals. (cause and effect) Everything counts, even the material of the wallpaper.
So, my standing waves are different to yours due to the different room sizes and material of the walls etc.

Individual room treatment is mandatory for an excellent SQ. In other words, a very expensive chain will have a nasty SQ in an untreated room, and a small budget chain will have a superior SQ in an optimal treated room.
 
This is my experience over the last 25 years, even with XXH.

Hi Boleary,

Room treatment is related to acoustics. A simple definition is "acoustics deals with what sound does in a room" (see "Acoustic Design For Home Studios" by Mitch Gallagher, chapter 1)

The room treatment is the physical basis (controlling reflections and reverberation, bass traps etc) for a superb sound.

Joachim

Hi Mani,

the conclusion with the experience of all participants of this thread is, Peter has to program/modify an OS destined for XXH only to get a consisted basis for future (next 10 years)upgrades.

Joachim

P.S. I will not give up Computer Audio since W7 is supported until 2020, but I have to buy a new Audio PC soonest.

Hi Coen,

no, it's too late now.

Joachim

Had to go back to W7  due to the “small ball like soundstage” in the center (mono effect) and missing 3D room image. 
Now the soundstage and the resinous sound of the violin are back. (my listing SPL is well below 80dBA)

The abnormal SQ differences between W8 and W7 could be PC (built in 2010) related.
Under W8 with the "W7 Shell" installed, the boot manager was not working and an access to the BIOS was not possible anymore (on my PC).

Joachim

Following this thread the result will be:

In other words,
we will have two XXH versions in the future, one for W7 and one for W8.

see Peter's sig.

Joachim

I had the similar problem with W7. Sound is gone, the slider of the time scale is still moving. Pressed the "Stop" and "Play" button again and it works until ........... .

I do believe that this behavoir is related to the tweaks.

Joachim

NO, MS is supporting W7 with updates until 2020 according to their statement last year.
