This image is from RME a sound card maufaturer. And the image is of the analog output after dac. So still in the electrical domain. Short comings of a playback system has what to d…

Frequency response and dynamic range are low hanging fruit in high res audio debates. They are not the only factors in accurate reproduction of an input wave. What is rarely consid…

http://www.eirec.com/DPimages/digisqwvtest.jpg Here is an example of higher sampling rates being useful INSIDE the human hearing range. This example shows transient response. Frequ…

More to it than frequency response and dynamic range. The goal should be for the most accurate reproduction of the input waveform. Here is a pic of transient response for different…

http://www.eirec.com/DPimages/digisqwvtest.jpg Okay here is a picture of what I'm trying to explain. And the author of this picture used a frequency much further inside human heari…

Good an audio nerd. I am making the point about the square wave close to the nyquist to point out the short comings of a format for accurately reproducing an input. Square waves in…

Okay now actually look at the response on Matlab. As you get closer to the nyquist freq there are less samples to describe the wave. And while you get a bastadised 18k signal it's …

There has been a lot of talk about quantative aspects of but little about the qualitative. What does a 18khz square wave look like wher recorded and reproduced in 44.1 kHz. How is …

This test is flawed in a few ways. The and the error lies in the source material. The why would there be a perciveable difference between the same inferior input shown to both enco…
