Broadband Noise Reduction (BNR) And Hum Removal
Includes both TDM and AudioSuite versions of BNR
Two powerful new features in BNR-A/S:"Audition Noise" and "Artifact Removal"
Automation features including dynamic Real-Time Plug-In automation
DINR is Digidesign's award-winning Intelligent Noise Reduction Plug-In for real-time, high-quality reduction of both broadband and pitched noise. BNR-A/S was recently added to the DINR package for broadband noise reduction of both broadband noise reduction in the File-based AudioSuite environment.
Software based module
DINR is a software based, digital signal processing module designed to reduce the full spectrum of unwanted noise, from air-conditioner rumble to guitar-amp buzz. With DINR's impressive new AudioSuite functionality, high-fidelity digital noise reduction is now available for all Pro Tools Systems.
Broadband Noise Reduction
DINR reduces broadband noise, such as tape hiss, by iintelligentlyi subtracting the noise from the digital audio file. First, the noise signature is created by selecting and analyzing an example of the noise within the source material. (A brief, isolated passage of noise is ideal but not necessary.) Using this signature, the effects of the noise are then removed or greatly reduced.
BNR Audiosuite
BNR for AudioSuite is identical to the real-time TDM version, with the addition of two new features: iAudition Noisei and iArtifact Removali. iAudition Noisei allows you to listen to the noise being removed from the target material, making it easier to fine-tune adjustments for maximum noise reduction and minimum signal loss. iArtifact Removali applies post-processing to the audio file to help remove undesirable artifacts that may result from noise reduction.
Hum Removal (For use with DSP Farm only)
DINR for TDM offers Pro Tools owners a second mode specifically for cancellation of pitched noise, such as hum and buzz. DINRis Hum Removal offers specialized digital filters to isolate and render the noise virtually inaudible, providing a more DSP efficient option.
A High-Fidelity Solution
Once the noise is analyzed, processing can be applied in real-time during audio playback. An on-screen slider can be used to apply from 0.1 dB to an infinite amount of noise reduction. Other parameter settings can also be adjusted ion-the-flyi to achieve maximum noise reduction while minimizing signal loss and artifact generation. To help assess the result, DINR features a bypass button to allow comparison of unprocessed and noise-reduced source material during playback.
