Getting back to the original question I think 1 khz is a fine place for a basic distortion measurement. I'd like more info, but picking one frequency the 1 khz isn't a bad choice. Why? The 3rd harmonic is often the highest in distortion with most gear. It is an odd harmonic making it less...

It is super simple. Hot Schiit is smoother than cold Schiit. What more do you need to know?

I think you make a very important point. I have assumed mostly you can forget about most modern gear as having a sound. I think probably more than any other time in history that is true. However some people design for a sound which isn't about fidelity. And some seem intent on shearing the...

Okay, the LSR305's are excellent speakers for something their size and better than you can get possibly anywhere else for the price. Unless they are malfunctioning or you are using them inappropriately (using them in a huge room expecting the little boxes to fill it with sound at high sound...

Don't buy a Eitr. It won't fix your problem. I suggest as others simplifying the system and checking things one at a time. Surely someone could bring over a smartphone or other music source you could plug directly into your 305 speakers and see how that sounds. Is your computer running...

The 305s should not sound muffled. I have some and they are pretty nice. They will do better in a larger room than many small monitors intended for up close use. Do make sure you have the sensitivity switch on the back set to -10 dbv. If the Magni is working right it really shouldn't harm...

You might also think about the fact one can digitally record an LP, and the sound is that of LP. The imaging differences, which are real, are captured in the digital recording. Which means LP imaging can incidentally create some pleasing imaging artefacts. Same thing can happen with tube...

In Audacity, under preferences, look in the Interface section. You can choose the depth of metering up to -145 dbFS. Audacity however adjusts the lowest level based upon the lowest part of the signal shown. So even with a -145 db setting it might show only down to some higher level if there...

Here I put a 13 khz sine wave in both channels, but offset by 2 samples at 192 khz. That would be about halfway between samples in a 44.1 khz sampling of them. I then downsampled this to 44.1 khz and upsampled to 192 khz again. Notice how the two channels are still offset exactly 2 samples in...

I am posting much the same thing 71 db has. Here is what I did. Created a pair of pulses at 192 khz rates that were 2 samples apart which is just about 10 microseconds. Then a pair 4 samples apart which is about 20 microseconds. I then resampled it to 44.1 khz. Then upsampled it back to 192...

Your problem is that yes, even with 23 microsecond sample intervals digital audio can capture everything that happens below 20 khz. For starters if it begins and ends in less than 23 microseconds it is by definition at a frequency above 22 khz. If you are referring to changes in sound that...

Okay what you are seeing are the recordings of the cymbals I mentioned. I would credit the site with them, but forgot while I kept files I downloaded. Recordings were done at 176/24. The response is above the noise floor to 60 khz. I seem to recall these mics had 40 khz rated bandwidth...
