NMP 2.28.1 is out! It now supports a new Adaptive Loudness Compensation (ALC) DSP which could be found in Neutron HiFi DAC V1 (the same DSP core). In addition, implemented support for WebP album-art, improved HiBy DAPs support and, of course, fixes...

In this release we’ve ported ALC DSP found previously in Neutron HiFi DAC V1 directly into the player software.

What ALC DSP does: Its full name is Adaptive Loudness Compensation (ALC). It intelligently adjusts the frequency response based on the volume level, ensuring your music sounds rich and full-bodied even at lower volumes (where the human ear usually loses track of bass and treble). It's essentially "smart" loudness that respects your dynamics.

DAC V1 is now supported by Sony PlayStation and Nintendo Switch game consoles!

Newest Firmware 69 + NConfigurator 1.9.2 add pure UAC1 support (see pics) and a volume correction option for PS5.

⚙️For embedded developers, this may be of interest - (STK) was recently updated: C interface, Multi-core support (AMP), embedded RISC-V support verified on
Raspberry Pi Pico 2 RP2450 MCU.

STK can easily replace FreeRTOS and is featuring higher performance with Os optimization, MUCH lower source code footprint, does not require board-specific porting - so you can make it working on any board with a compatible MCU.

It is C++ AND now also C, thus you can add it to you embedded project without a hassle and steep learning curve 😁

With Firmware 57 Neutron HiFi DAC V1 got new unparalleled sonic performance. While sounds like magic it is the reality provided by the unique feature of ESS DAC chips which allows to fine-tune hardware in post-production stage when all components are installed and affecting the audio signal.

Details of measurements of all affected modes (2Vrms, 1Vrms, Voltage or Current mode) are posted on AudioScienceReview forum:

New measurements show much improved SNR/DNR in comparison to the initial ASR's review that means more space available for a sound wave with real audio content. The lower 2-nd and 3-rd harmonics, the more space is available for sound.

Neutron HiFi DAC V1 Review This is a review, listening tests and detailed measurements of the Neutron HiFi™ DAC V1 portable DAC and headphone amplifier with signal processing (e.g. EQ). It was sent to me by the company and costs US $180. I didn't think it was possible to give a feeling of luxury and style to a dongle...
