NCH Software DeskFX Plus v5.15

NCH Software DeskFX Plus is a Windows audio enhancement utility that processes sound playing through your computer’s speakers or headphones in real time. Rather than serving as a DAW instrument, it focuses on system-wide listening adjustments for music, video, games and streaming services.

Its equalizer offers up to 20 bands, with visual, graphic and parametric modes for shaping the frequency balance. You can add bass, adjust amplification, or combine reverb, chorus, wah-wah, vibrato and tremolo to change the character of playback. Low-pass and high-pass filters help reduce unwanted frequency content, while support for unlimited effects lets you build layered processing chains.

DeskFX Plus suits hobby producers and everyday listeners who want more control over their Windows playback setup. It can help tailor speaker or headphone sound to personal preferences and the listening environment. The straightforward interface makes effects adjustments accessible, and its low latency and CPU usage are useful when processing audio during live streaming. It is a playback-focused utility, not a replacement for mixing tools inside FL Studio or Ableton Live.
