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 do with the accuracy of a recoding…
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 considered is the temporal resolution of the…
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. Frequency response and dynamic range are low…
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 sample rates.…
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 hearing range. This is transient response…
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 the real world are rare but I am…
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 a far throw from what you put in. Anf…
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 phase affecte?. Phase of an audio…
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 encoding formats. Changing between encoding…
