  • High Pass Filtering (HPF) with slopes up to 36 dB/Oct
  • Low Pass Filtering (LPF) with slopes up to 36 dB/Oct
  • Five bands of Notch filtering with linkable frequency control
  • Analog Saturation Modeling
  • Double precision processing
  • Low Latency
  • Mono and stereo versions

Accurate high pass and low pass filters reduce low frequency rumble and high frequency hiss. Selectable slopes of 6, 12, 18, 24, 30 and 36 dB/Oct and frequency control range covering the entire audible spectrum make the NF575 filters extremely flexible.

Advanced notch filters allow the user to select the amount of signal cut, cut frequency, and width (Q). All five NF575 notch filters can be linked harmonically to address common cyclical noise problems such as 60 Hz hum.

Buzz Removal

Cyclical noise like AC power hum is all too common in audio production. While a simple notch filter may remove some of this kind of noise, there are often several harmonics of noise that require multiple notch filters, often with varying amounts of reduction. The NF575 notch filters are extremely narrow and linkable, so the removal of cyclical (and harmonic) noise is possible, without affecting the desired audio.

NF575 Low Rumble Removal

Low Rumble

Often a well recorded track can still have unwanted signal content; the singer’s plosives (ex: a really loud ‘buh’ sound when screaming ‘baby’ at the top of your lungs), the rumble from a mic stand, wind, or other low frequency signals that spoil the quality of the audio. Using the NF575 high pass filters, these types of sounds can be easily removed. The steeper slopes can remove more of these unwanted sounds, while preserving the real content in the track.

Phasor Effects

While the NF575 is really designed for noise reduction, the NF575 notch filters can create some pretty drastic phasor like effects. Link all 5 notch filters to the first notch using the link control, select a wide Q setting, and then vary the frequency control in the first notch filter (band 1). The effects are interesting, and by automating the frequency control of the first notch filter, the phasor sweep can be made into a consistent effect during playback (instead of locking to the rate of an LFO, which could produce different phasor effects each playback pass).
