The earliest AV receivers capable of 5:1 sound couldn't resolve above 48. I had an old Sony amp a few years ago that could do Dolby 5:1 but not TrueHD.

The big limiting factors when it comes to sound quality are room acoustics and speakers. All other aspects of sound reproduction (assuming the amp is powerful enough to push the speakers) are dwarfed by an order of magnitude. Even the best speakers reproduce the signal with only a reasonable...

SACD is indistinguishable from standard CDs given the same masterng, which is the exception, not the rule. I did line level matched comparisons between CD and SACD and I had to search high and low for a hybrid dsk that had the same thing on both layers. Most had deliberately hobbled redbook...

Audio and video technology has reached a point where image and sound quality have reached peak optimal resolution. You can screen a 4k scan and high bitrate audio, but in the typical home, you aren't going to see improvement over 1080p and redbook. I'm sure video will go the same way that audio...

Another category of aural offender is when a movie has hit songs cut in and they use the music master instead of the movie track. The example that springs to mind is Hard Day's Night. Every time a song comes on I have to reach for the remote to adjust the volume. Some effects movies have screwed...

Yes. Alice and Dumbo have the worst 5:1 mixes I've ever heard. Fantasia is the only one that sounds decent. Restraint and good taste isn't exactly the hallmark of Disney home video.

I've supervised sound mixes for TV, and knowing that the mix is going to sound the same at home as it does on the mixing stage is a huge problem. A standard for flat frequency response and relative levels between channels would go a long way to help that. Having the director supervise the sound...

Preringing occurs in such a brief time frame... Less than one cycle of a frequency... there is absolutely no way that a loudspeaker could possibly reproduce it, and it's doubtful whether human ears can even hear it if they could. The best apodizing filter is the transducers themselves. Also, the...

That's the Achilles Heel of all upconversion schemes.

At what volume level does this preringing occur in relationship to the peak signal? 50dB below? 70 dB below? I'm willing to bet that any preringing artifact exists miles below the noise floor of even the quietest living rooms. (Unless you listen to your blurays at volumes beyond the level of a...

I've worked with a 24 bit ProTools workstation, and had a chance to do some experiments and listening tests on very good equipment. For normal playback, plain old redbook is all you ever need. The difference between high bitrate sound and redbook is the depth of the noise floor. If you're...
