The NF575 Noise Filter offers a powerful solution for removing various types of noise from audio recordings. Its high-resolution high pass and low pass filters effectively reduce unwanted low frequency rumble and high frequency hiss, ensuring a cleaner sound. With selectable slopes ranging from 6 to 36 dB per octave and a frequency control that covers the entire audible spectrum, the NF575 provides precise and adaptable filtering capabilities.

Equipped with five advanced notch filters, the NF575 allows detailed control over signal cut, cut frequency, and bandwidth, enabling the removal of cyclical noises like 60 Hz hum. These notch filters can be harmonically linked, making it easier to target and eliminate common harmonic noise without compromising the integrity of the desired audio. The narrow notch filters excel at buzz removal while preserving audio quality.

Additional features include steep filter slopes to effectively remove low rumble while maintaining the track's original content, and a real-time analyzer that provides visual monitoring of the frequency spectrum. Available in mono and stereo versions, the NF575 ensures zero latency processing and supports multiple plugin formats. A collection of presets from award-winning mix engineers further enhances its usability for audio professionals.
