WAVEFORM STATISTICS
Waveform Statistics supplies the audio
engineer with useful information about the
peak, RMS, and loudness levels of the audio,
as well as potential warnings about DC osets
and clipping.
It’s accessible via View in the upper menu bar.
EQ
RX 4 includes a four-band parametric equalizer
module with adjustable notch filters and
low-pass/high-pass filters. This is a handy tool
for cutting or boosting certain frequencies, or
for quickly removing unwanted low or high
frequency sounds like rumble and hiss.
The EQ module comes in two EQ Types:
Analog EQ is a non-linear phase filter. The
Linear-phase EQ uses a FIR (finite response)
filter. The analog filter applies a very dierent
(some say warmer) character compared to the
linear phase filter, which is very precise and
designed to minimize phase shifts in audio.
You can easily switch between the two filters
to hear which best suits your project.
