DINR
Digidesign Intelligent Noise Reduction (DINR)
consists of a pair of DSP plug-ins (TDM and
AudioSuite only) that provide two types of noise
removal:
Broadband Noise Reduction (BNR) Provides
broadband and narrowband noise reduction for
suppressing such unwanted elements as tape
hiss, air conditioner rumble, and microphone
preamp noise. BNR is available as a real-time
TDM and as an AudioSuite plug-in.
Hum Removal Removes pitch-based noise such
as guitar pickup buzz, AC line noise, and fluores-
cent hum. Hum Removal is available as a real-
time TDM plug-in only.
Broadband Noise Reduction
The Broadband Noise Reduction module (BNR)
removes many types of broadband and narrow-
band noise from audio material. It is best suited
to reducing noise whose overall character
doesn’t change very much: tape hiss, air condi-
tioner rumble, and microphone preamp noise.
In cases where recorded material contains sev-
eral types of noise, the audio can be processed
repeatedly according to the specific types of
noise.
For noise that has more of a pitched quality, the
Hum Removal module may yield more satisfac-
tory results. See “Hum Removal” on page 72.
The TDM version of Broadband Noise Re-
duction is not supported at sample rates
above 96 kHz. The AudioSuite version of
Broadband Noise Reduction supports
192 kHz.
Hum Removal is a Macintosh-only plug-in.
It is not compatible with Mac OS X,
Pro Tools version 6.0 and later,
Pro Tools|HD or 24|MIX cards. It requires a
DSP Farm to operate.
