Firmware 61: Neutron HiFi DAC V1 – PEQ DSP got way better!

The latest firmware update brings a significant enhancement to the Parametric EQ (PEQ) DSP engine.

🔧 What changed?

● PEQ DSP math was upgraded from 32-bit floating point to the fixed-point processing for a higher precision math.
● This change reduces quantization noise considerably at low frequencies.
● New fixed-point DSP code is the same high-performing and allows up to 40 PEQ bands, per channel in a tiny portable device!

🎧 What does it mean for your music?

● Tighter, cleaner bass response.
● Improved dynamics and sonic depth.
● A more powerful, engaging experience - especially noticeable for fans of bass-driven, dynamic, and punchy music styles.

🔎 How it affects FRC (Frequency Response Correction, 10-band PEQ DSP):

● With the new fixed-point processing, FRC delivers more accurate correction curves, especially in the bass region where floating-point math used to introduce subtle noise.
● This means headphone users can enjoy cleaner, truer response compensation according to the AutoEQ or your personal FRC preset.

This refinement ensures that your listening sessions are not only precise but also more immersive and energetic. Whether you love electronic dance, hip-hop, rock, or any genre that thrives on deep, impactful lows, you’ll hear and feel the difference!

Neutron HiFi DAC V1 also supports other useful DSP, such as Crossfeed, Surround, check details in its specification page: https://neutronhifi.com/devices/dac/v1/details
