iZotope RX 3 Advanced — It’s Delovely
a Friday at 4 p.m. Just one hour before the weekend begins. Your
program director walks into your production studio with a reel of
tape and asks you to “clean up” the song he just found in his
office for the upcoming “Retro Weekend.”
hope your reel machine still runs. Then you start worrying … Will
the tape be in phase? What about hiss? Was it dubbed from a record?
Maybe there’s crackle?
I’m here to tell you that you need not worry, my friend. Meet
iZotope RX 3 Advanced noise reduction/audio restoration software.
all under time constraints and nobody wants to spend hours trying to
figure out editing software. So iZotope took this into account when
designing RX 3. The layout and ergonomics of the program make it
super-easy to understand. Your eye can easily find the button for the
task that you wish to accomplish. From declipping to decrackling,
noise reduction to phase alignment — iZotope RX 3 Advanced has it
all. I especially like that you can view the waveform and spectrogram
display simultaneously making is super easy to edit and restore your
program also allows you to add AU and VST plug-ins so you can make
this your primary editing suite. However, in future releases I would
like to have an option to build a mastering chain. For example, if I
decide I want my EQ settings before noise reduction, instead of
after, I have to undo my work. If a mastering chain existed, I could
simply slide the EQ before noise reduction and be on my way.
Hopefully we will see this in an upcoming (maybe the next?) release.
thing that immediately caught my eye upon launching RX 3 was
that’s right. Dereverb. How cool is that?
I really wanted to test this tool out. I took a recording I made of a
popular artist and loaded it into RX 3. I had placed a decent amount
of reverb on this recording of a female singer and her guitar. Now, I
wanted to see if RX 3 was up to the challenge of removing the reverb.
was impressive. While there was a slight trace, the reverb was almost
completely inaudible, and I could not detect any artifacts. This tool
really comes in handy if you no longer have a session file and are
unable to mix the reverb out of the recording. This was cool!
you have read my articles, my love for 1920s and ’30s 78 rpm
records would be all-too apparent. I am always eager to try new
remastering software when it comes to restoring and preserving the
integrity of the original recordings. I have worked with several
software programs regarding this matter and RX 3 is right at the top.
It did a beautiful job of removing surface noise without creating
artifacts. It is important to remember that you can’t take out
everything. You do have to leave some noise or the recording will
I pushed RX 3 Advanced to the limits, and it sounded clean. The
interface was easy to use and allowed me to be precise as to which
frequencies I wished to attack. The Remove Hum module didn’t let me
down, either. I purposely removed the ground from my turntable to get
a nice 60 cycle hum. After running the dehumming filter, my recording
sounded fat and full … minus the hum. Declicking was also a simple
task. I tested this with a record that had minor groove distortion.
To my surprise, the Declicker went above and beyond, removing most of
the groove distortion. A nice side-effect, indeed. Although a word of
caution: If you overprocess with the Declicker or Decrackler, you may
get an unwanted gurgling sound, so be careful.
3 comes equipped with time compression/expansion, phase correction, a
spectrum analyzer and EQ.
used much more modern recordings to really get the feel of how well
the program handled altering the audio of a song recorded and mixed
in the last 15 years. I was pleased with the time compression and
expansion feature. Whether I wanted to alter the pitch or change the
BPM, RX 3 did not disappoint. There were little to no artifacts left
in the music after I compressed a three-minute song by 10 seconds. RX
3 really gives the user the ability to adjust the transient
sensitivity, pitch coherence and noise generation of the tool so your
recording will sound just right after alteration. However, I was
frustrated that I could not see a display on the duration of my audio
file. The Time and Pitch tool only displayed in percentage, not
duration. This made things take a little longer when I wanted to
shrink the size of my recording.
you have ever needed a good tool to extract the vocal from a song, RX
3 would be a fine candidate for the job. Like anything else, you have
to play with the settings to get the balance just right, but RX 3
makes it easy to extract the center channel and retrieve the vocal
from a song, if you wish. This same tool also helps you adjust the
phase and azimuth of your recording. This is especially helpful when
transferring old cassettes that were sometimes recorded out of phase.
