Oh Gods! I'm happy with the recent discovery! I use Fedora 38 and was looking for a convenient, practical and adequate way to play tracks from Qobuz under Linux. In Windows and MacOS there are no problems with this thanks to Audirvana. But under Linux everything is different. Yesterday, while...

I can confirm that qobuz, played back in firefox (on Linux), perfectly switches the sampling frequency of my smsl m500 DAC to the frequency of the track. Just a delight! Chrome doesn't do this for some reason. And no other programs are needed to play qobuz. The problem of playing tracks from...

How interesting. You can try to simulate the driver yourself thanks to these suggested models. What an interesting time we live in! https://www.comsol.ru/story/designing-the-gold-standard-of-immersive-audio-for-virtual-reality-gaming-90331

It can be seen that the required firmware file is in your folder, the name of which contains hieroglyphs. Maybe this is driving the program crazy? Try to locate the firmware file simply on your desktop.

hmm ... but where did this comb around 1kHz come from?

does your ST-Link have the latest firmware on board? (ST-LINK FW : V2J38S7)

When everything is soldered and connected. Then everything is simple:

I watched the topic "high 3rd harmonic". I also found this problem on my device. This caused frustration. Yesterday, thanks to @jdoe, I decided to reflash my device. Recently I have been studying programming of the STM32f103 microcontroller and realized that reflashing the device would not be a...

If the firmware is dated from last year, how can it fix the problem that was discovered this year? Have you tested your device after flashing?

I listened to a stationary signal with a "comb" and compared it with a signal that did not have a comb (at a close, adjacent frequency) but to which I added amplitude modulation. And indeed, when I added modulation, it was audible, but when there was just a visual comb, it was not audible. Thank...

I understand. it does not make sense.

Settings Hann FFT 8192

Also 16000Hz and 9600 ..

I tried an experiment. I generated a sinusoidal signal, the frequency of which ranged smoothly from 11999Hz to 12001Hz over 300 seconds. The sampling rate was 48000Hz. The bit depth is 32. I did this inside the Izotope program. I also did the same by connecting the balanced output of my S.M.S.L...

Can I ask you to make graphs of the same size? After all, the purpose of graphs is to compare different devices. You can open several browser tabs with different test graphs and switch between them. And compare. And if the graphs are of different sizes, they will complicate the comparison a...

Fine! Here it is, the correct graph for displaying harmonic distortion. It can be seen in what places and with what harmonics there may be problems.

I heard with confidence how my favorite albums sounded in mqa. Disappointment. I will never use mqa. It's worse than CD. But it is better than some of the other types of compression.

Interestingly, the fundamental harmonic can be a standing wave in the room, and then the presence of additional harmonics due to distortion is even more audible. Those. you move into a space where the fundamental tone is subtracted and becomes quieter, but the 2nd or 3rd harmonic (due to...

It's funny .. my reworked Microlab Pro 3, which I reworked a bit (changed twitter and redesigned the crossover). It played through SMSL M500 and Aiyima A07 on TPA3255. Distorted frequency response(not very good location of the microphone when measuring), but better thd distortion than some...

I also see that this speaker is good too: neumann-kh-310a. But, perhaps Revel will be better ..
