Hi, I received the newest beta (thanks a lot Wiim Team for your swift reply). I don't have so much feedback to add... All works smooth with various bitrates.
@WiiM Team,
With the beta firmware 4.6.434457, via the analog aux output:
- 0 dB, 1k tone - still see some distortions (screenshot 1)
- anything below 0 dB, only the background noise, not visible, below -100 dB (screenshot 2)
Great to know also your feedback.
I still don't understand the harmonics at 0 dB, with the 1000Hz tone test. Maybe that is a different issue in the DAC of the WiiM.
Otherwise the results we have are consistent below 0 dBFS.
I got the 22/09 firmware 4.6.430138. I repeated the tests and:
- The 0 dB sample still produces distortions
- Anything below does not produce distortions
- No more 'limiting' e.g. you see differences in output level now (versus no difference between 0 to -1,1 dB)
So, I think only partly...
With the current firmware 4.6.434158, I performed some tests:
Test in Adobe Audition entirely in digital domain: original generated tone of 1000 Hz at 0 dB (left) then increased the volume with only 0,3 dB, saved the file and opened again (right). See the distortions (harmonics) appeared...
