The NF575 HD Noise Filter v5 from McDSP is a noise reduction plug-in designed to remove a wide variety of noise types from audio. It features accurate high- and low-pass filters to help reduce low frequency rumble and high frequency hiss.
Slopes of 6, 12, 18, 24, 30 and 36dB/octave can be selected and a frequency control range covering the entire audible spectrum make the filters extremely flexible when dealing with noise problems. Advanced notch filters allow the user to select the amount of signal cut, the cut frequency, and width (Q).
All five NF575 notch filters can be linked harmonically to address common cyclical noise problems such as 60Hz hum.
The NF575 HD HD v5 plug-in provides TDM functioning for Pro Tool HD, but also includes an Audio Units version for use with DAWs that support the format, including Logic, Digital Performer (DP) and Ableton Live. Additionally, a third party software application that supports the TDM, RTAS, or AudioSuite plug-in standard can also be used.
