TestHiFi intro and motivation
Why TestHiFi? Non-technically interested friends used to ask why we do such a thing as the TestHiFi app.I could have answered with the words of another friend, who, when asked “why” about his super-elaborate tube […]
Digitalization – how far can it go?
Just recently I came across a new album, composed and played by AI. Also I found quite an interesting theses on the digitalization influence to the music business. This blog cites abstracts of those. Music […]
Hi-Res, yes but …
Digitalization used to be a harm to the quality of music reproduction. In the early days music digitalization, it was quite difficult to cut the analog information in small enough digital slices. That was on […]
Different harmonic distortions at different places?
Why would you get different measurement results for harmonic distortion at different places? In several of our other blogs, we talked about harmonic distortion. https://testhifi.com/2019/03/15/the-sound-of-distortion/ David explained why they are. Also we talked about acoustical […]
You can hear the difference – listening example
Any system plays music it is just a question of how close it comes to the original. The question of hifi, high fidelity. The two audio files attached play the recording’s taken at the same […]
Position is key
Influences to the frequency response Sure, we all know about and talk about the frequency response. Measuring amplitude over frequency. Of course, this is far too profane for a proper audiophile to have a seriously […]
Air between the tones
Very subjective view on some highly appreciated sound experience events This time I write about air between the tones and some of my recent listening experiences and about some thoughts about better measurements of sound […]
