I know my proposal is not a standard and maybe even nonsensical but here it goes. Did some dgging into spectra of music in AES papers and other research (also from MQA Bob) and found quite a lot of data on the spectra of music. Even across various genres which do have some differences but aside...

Here is a video that analyzes the difference between analog and digital recording. Of course this has nothing to do with sound quality nor the consumer audio reproduction side but the guy in the video above makes some interesting points for the recording side (the creative side)

and are interested in audio illusions psycho-acoustics/perception you should watch these excellent videos (in the order below) 1 of 7: 2 of 7: 3 of 7: 4 of 7: 5 of 7: 6 of 7: 7 of 7:

Just checking to see if there is an interest in planning a meet (in the Netherlands) between members (maybe even some Belgian and German members close to the Duct border ?) When there is enough interest I could see if there would be a possibility to set something like this up somewhere central...

Here is a fun test for you to try. 5 x the same excerpt of a live recording. All MP3 VBR0 48kHz. (I know... should have been FLAC but that is 3.5x the file size) the differences have been preserved. 1 of them is the original 4 of them are the same excerpt but have undergone the exact same EQ as...

This poll is born out of a 'soundstage / imaging' discussion. I am just curious how people hear headphone 'soundstage'. Note this is with 'normal' recordings so NO binaural recordings and without any processing/plug-ins like crossfeed, stereo enhancers and 3D emulators. Just a plain...

New Sennheiser pads (HD580, HD58X, HD600, HD650, HD6XX, HD660S) As of medio 2021 Sennheiser is sourcing their pads from another (I assume much cheaper) supplier. Sennheiser mentioned there is very little difference in sound and differences within the entire audible range will be smaller than...

There has been some discussions about pad thickness. Mostly about the DT990. I took some headphones I have lying around (all with lots of hours on it already) and put these on my flatplate. Measured the pad thickness on the outside and then pressed them onto the rig using velcroband around the...

really cool retro. I really like it. Too bad it's a bit too expensive.

I am curious about what 'audio science review' members do for a living (or are retired) and if they have hobbies other than audio. I'll kick of. Daily job: is designing, building (manufacture), FAT and service electronics for railway measurement systems. Used to work in audio/video repairs...

Above the 440Hz square-wave of the HD800, below the HD650. The HD650 produce about the best squarewaves I have measured to date.

Just curious ... What headphone(s) do you currently own ? Which one(s) is(are) used the most, or is your favorite ?

Feeding/charging a low-current draw device from a powerbank is not going to work with most powerbanks. The reason for this is that a powerbank has an internal battery of 3.7V. In order to get 5V from an output there is a step-up converter present in the powerbank that puts out around 5V. Such a...

Hi Guys, Thought I'd join. Probably will not be posting that much due to being a bit too busy and a second reason listed below. Family, hobbies, website, forum, lots of e-mails, daily job etc. limit the time I can spend. But maybe I have it wrong and might post a bit more than I think I will...
