Testing audiophile claims and myths
As far as I know, only projectors can reproduce REC2020. Many of them can do 100% of DCI-P3. Emissive displays are just barely hitting DCI-P3. Only a handful can do 100% of P3.- dprimary

Makes sense, for many years I only specified 4k or UHD displays for interactive and collaborative applications.- dprimary

Testing audiophile claims and myths
You didn't specifically call out Dolby Surround 7.1, when I read it I had the same reaction as Gregorio that 7.1 has been around for decades. From a mixing perspective for film, I consider all speakers but except the center and LFE to be part of the surround. In non atmos surround formats the...- dprimary

ANY difference between balanced and single ended (other than volume & noise?)
What the the engineer told you is pretty much the trade off. If you want to more the paper from Bill Whitlock can be downloaded here - www.jensen-transformers.com/application-notes/ you will have to register which should be free and they are worth the effort.- dprimary

That is a broadcast standard. It does not apply to SPL or loudness in a live venue. It would only apply to the broadcast feed of the live event which is whole different mixing desk and processing chain.- dprimary

One would hope the artist listened to the album song levels as it was mastered, so the the album flows with listener adjusting the levels, we often lowered individual song levels a few dB to give a consistent levels from one song to the next.- dprimary

0dBFS is the same on every piece of equipment and software I have used. I can record the same signal with 8 bit, 16, 24 and 32. They will all play back at the exactly the same level the only difference will be the noise floor. Bit depth only pushes your noise floor down. There is only two...- dprimary

Testing audiophile claims and myths
I missed your post before. I think we are saying the same thing from the opposite direction. It really depends on the room you can have large bright room or a dead one. Unlike music studios where the acoustics and monitors are referenced to "flattness" The x-curve is reference made from the...- dprimary

That page is horrible. The simple fact they have different "headroom" for different bit depths is flawed. Digital has the same headroom no matter the bit depth. It has been said "footroom" would be a better term. In music recording headroom is something you leave yourself for peaks. So is they...- dprimary

X-curve (See SMPTE ST 202) is applied to the measurement window. It is not really an eq curve. It is based on the average theater size of 500 seats, the x-curve is what was found to be the typical response in testing many 500 seat theaters (it was also developed a long time ago) What it does...- dprimary

Are they adding distortion to "create bass" of is the distortion a side effect of using the rumble motors to extend the bass making the whole tablet a LF driver. Much like the old servo drive subwoofers, except without a direct connection to the driver surface and a whole lot of real time math.- dprimary

Testing audiophile claims and myths
That is the problem with analog recording there never has been an analog recording system that does not change the sound, you are always losing something. The signal from the microphones has never played back on an analog recording sounding anything like what went in. With experience you learn...- dprimary

There was bunch of different ones all with artifacts, Dolby A and SR, DBX type 1, Telefunken C4, EMT. SR was the only one that had much acceptance and that was only in film. Then there was all the low performance consumer schemes Dolby B,C and S, DBX type 2 and Telefunken high com.- dprimary

Testing audiophile claims and myths
The scary part it modern touring systems are so clean and have so much headroom in most venues, you don't even notice how loud it is. When it harsh and distorted it easy to notice. I was at and outdoor jazz concert a few years ago near FOH thinking this sounds really good, then a few minutes...- dprimary
