Quality basics: please improve digital volume control

[planetti]

Dear WiiM-Team,

can you improve the quality of the digital volume control implementation? (Do you use e.g 64bit/dithering algorithms?)

The current algorithm seems to be detrimental to sound quality, apart from the numerical bit-reduction. This general improvement would be a gain for all WiiM devices and in the future.

Some users will not recognise, but many (current) users ask for 1:1 bit-perfect, which means that they are not satisfied with the current implementation. This user group may appreciate the WiiM technical quality level.

Perhaps it is possible to add a ISO226 adapted volume level correction at the same time.

Thank you for your efforts!

I did not get the latest firmware yet to try but I believe it is too much volume for my dac maybe , since when I lower the volume about 3db it does not sound hot , loud, and tense and gives me more granularity in the amp as far as the volume . It sounds so much better with lower volume compared to fixed volume and probably it overloads and distorts…

Hi joffy1780,

There is a volume table ranging from 0 to 100 that applies to both digital and analog audio output. Our DAC supports 32-bit input, which we utilize to maintain bit depth. Additionally, intermediate processing is designed to preserve sample value accuracy throughout.

Thank you very much, @WiiM Support
