Pro-Ject announces the ultimate vinyl noise canceller. Breaking away from the traditional approach of electronically cleaning up an analog signal damaged by scratches and dirt, the Pro-Ject NON Vinyl Box S3 Ultra introduces a revolutionary method. The Pro-Ject NON Vinyl Box S3 Ultra analyzes...

I just finished up researching and shopping for a new bedroom video/audio setup and I was surprised at how many things were different since I last shopped for AV stuff. I'll skip the video stuff... 4K, HDR, Dolby Vision, etc. It was the audio components that really surprised me. The TV I chose...

I was reading a book of short stories by Ambrose Bierce today and it included a ghost story about a phantom Civil War regiment. It mentioned the phenomenon called "acoustic shadow"- a battle that was audible in the distance 8 miles away in one direction, was inaudible in another direction a half...

I'm curious about microphone placement theories. I would imagine different instruments get miked differently. I know from personal experience that miking drums is not at all intuitive. Gregorio, how would you approach miking an acoustic piano? Are there different ways to mike it to get different...

I just heard of an app called Mimi that administers a hearing test and then exports a correction calibration that can be imported into the phone's Headphone Accommodations settings. Has anyone tried this yet? I plan to do it when the holiday rush is over. Sounds interesting.

Back in the early digital era, people were dumping record collections left and right. I already had a sizable collection of about a few thousand records, but seeing great LPs and 78s selling for as little as 50 cents a pop was too much of a temptation. My collection quickly grew to well over...

One of the old saws I keep hearing about lossy vs lossless or cd sound vs HD audio is that a difference might be audible if you use very "resolving" equipment. Has there ever been a study that showed that elaborate stereo systems reveal lossy artifacting at high data rates or HD audio...

I'm curious how well the head tracking and dimensional audio work in the Apple AirPods Max. Has anyone tried them with multichannel content? Or with stereo content synthesizing true speaker soundstage?

Haven't had a chance to read this yet, but someone suggested it to me on the Head-Fi Facebook page and it looks interesting. This is different from what I would expect. The Journal of the Acoustical Society of America: “No Correlation Between Headphone Frequency Response and Price.”...

Responding to: https://www.head-fi.org/threads/what-makes-great-detail-in-totl-headphones.918386/page-6#post-15525800 Shall I start offering my guests headphones instead of listening on my 5.1 speaker system? I can do that, but the whole point of a speaker system is soundstage, and you don't...

Interesting video that asks if Western music is responsible for how we think about pitch.

Today I got into a discussion on the Head-Fi social media group with a fella who said that 95% of Head Fi posters don't focus on music or sound quality... they focus on gear. He was trying to explain to me that people who describe equipment in flowery subjective ways do that because the gear...

Here is a fun exercise for us... Choose one of these ten types of cognitive bias and think up a way that it relates to home audio. Just do one, don't burn through all ten. Leave some fun for everyone else to choose one too. Click through the links to the detailed definitions. Extra credit if you...

This guy is *exactly* like the salesmen they used to have at Pacific Stereo back in the 70s... unassuming yet still hard sell (just try disagreeing with them!) and completely wrong. It's nice to know that old school high end audio salesmen still exist.

Wishing a great 2019 to Sound Science and its devotees.\

I've never run across this myself, but I was reading in another forum about a person who bought a FLAC download of a classical album by BIS that sounded like it had a frequency boost in the treble and upper mids. He ordered the CD and it played fine in his player, but when he tried to rip it...

These aren't my graphs, but a fellow poster here sent these to me because I was interested in seeing exactly what sort of content existed above 20kHz in 24/96 downloads. Take a look at these... http://www.vintageip.com/pics/brahmspianoconcerto2annamalikovadarlingtonallegro.jpg This one is...

Friday I got the new Oculus Go in from Amazon. I'm not a gaming person at all, and I've never had a chance to play with VR. My interest is in movies and music. But I can see this as having the potential to have a huge impact on the home theater market. It also suggests a few things about the...
