    Powering WiiM Pro Plus with a power bank

    Back to the thread topic ... Adam, it is undisputed that a clean and powerful PSU can improve the sound (depending on the internal noise and ripple rejection circuits of the sound device). Theoretically for our WiiM pros and minis, a native 5V powerful battery would be the best, a supercheap...

    Quality basics: please improve digital volume control

    Every digital processing has an influence on the digital signal, since the information is not the same as the original. Of course, there are algorithms (e.g. sophisticated tricks, filterings, interpolations etc.) which keep the distortion to a minimum or shift to inaudible regions. Depending on...

    Quality basics: please improve digital volume control

    If you do not tick "fixed volume" on 100% and if you use any EQ, the signal is processed and cannot be bit perfect any more.

    Convolver for Digital Room Correction and EQ fir filters.

    Dear FIR dreamers, from my FIR convolution experience there are some hurdles to pass. The hardware requirements for convolution is about the computing performance of a RPI 2B BruteFIR for 2 channels @192kHz, 65000taps. The miniDSP AD-chip, which is specialised on DSP calculations, provides...

    Room Correction Beta firmware for WiiM Pro, Pro Plus and Amp - User Testing Experience

    @canard Sorry, I do not understand your point. The topic here is "Room Correction", so we might take actual rooms with their room modes into account. The nature of music extends to the characteristics of the room - even for (my) 17Hz (9,7m) and its multiples, for deep sounds and base drums. At...

    Room Correction Beta firmware for WiiM Pro, Pro Plus and Amp - User Testing Experience

    Dear WiiM-team, concerning mic calibration of apple products, I get quite different results in a device room correction app (for a nubert subwoofer) by using different apple mobile devices (Iphone, 2xIpad). So I would expect not too much from the DRC results compared to an external calibrated...

    Room Correction Beta firmware for WiiM Pro, Pro Plus and Amp - User Testing Experience

    Dear WiiM-team, notwithstanding the results of the room correction tool (with its challenging aspects of mic calibration, target curves, low room modes, low filling dips etc), please extend the EQs additionally in the EQ-section to be manually fine tuned, channel separated.

    Loudness mode (Equal-loudness contour, or Fletcher–Munson curves)

    Dear WiiM-team, in the current FW there is an EQ called "Loudness". Please note that the Fletcher-Munson contour (ISO226) is not a correct interpretation of the loudness correction. The correct compensation is the difference between the curves with about 80dB (as reference level 0) = volume of...

    Quality basics: please improve digital volume control

    I have the subjective impression that the soundstage presentation is "reduced", the sound is "flatter", the instruments are more "diffuse" and a bit "constricted" - when the digital volume in the WiiM app is reduced while volume level is compensated, spdif coaxial out, on headphone and speakers.

    “Loudness” option - equal loudness curves based EQ for low level listening.

    Hi harkpabst, the adaption is done automatically, so the misuse argument is void. The user may only set his individual (letś say 80dB) level, additionally the intensity rate. Have you ever used e.g. RME adi dac having that functionality? Very convenient feature. This is more realistic sound...

    Quality basics: please improve digital volume control

    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...
