Use Cases
In many cases, it makes sense to use this tool on just one channel, rather
than on both stereo channels. is is the case when, for example, a ste-
reo pair of ambiance mics suer because of slightly dierent distances
to the source.
1) You have a DI’d bass track, which sounds annoyingly “D.I.ish,”
and you drop the track into the mixing project so you can re–
amp. You create a great, let’s say, Ampeg SVT sound and you try
to blend the DI track with the re–amped track and it sounds aw-
ful…
Just grab the RSPhaseShier, insert it into only one mono track
of the two bass tracks, and start o with what ever frequency, let’s
say 73 Hz, and play around with the phase angle…Bang! Sudden-
ly, it sound awesome and you are done. You just need to nd the
sweet spot so that you have a fat bass and both tracks complement
each other perfectly in terms of phase.
2) Another scenario would be a set of two, let’s say stereo, distorted
guitar tracks recorded with dierent guitars or amps but playing
the same ri. ey sound awful because both are modeling–based
guitar amp simulations. You insert the stereo version of the RS-
PhaseShier into one of those pair of tracks and play around in
the same way, aer you enabled Mirror mode, so that both tracks
are ganged. Within seconds, you will nd a sweet spot where
both guitars blend perfectly, because by sweeping through the
phase angle control, you’re applying very complex comb lters
which you could not create with EQ.
3) A common situation is you have closely spaced, multi–mic’d sources,
like a snare with top and bottom mics, some instrument with two
mics, or an acoustic guitar with a mic and a piezo pickup. Just play
around with the RSPhaseShier on one of the feeds, preferably the
one which is closest to the source, such as a piezo or D.I.’d signal,
and nd the sweet spot by feel.
4) Yet another would be you’ve made a great acoustic stereo recording
and have used supporting microphones, such as room, spot or far
hall placements. To meld these into your main stereo pair, take your
mains as the phase reference, and align one supporting mic aer
the other with the mains. is is easiest if your supporting sources
are panned center and approximately the same level during phase
alignment. Aerwards, you can set gain and panning back to taste.
5) Special Effects & Sound Design: Maybe you want to create
phase sweeps to “y a sound into the mix from outer space.”
Play around, especially with RSPhaseShifter within an MS
environment, to open a creative playground for fancy phase
tricks which are dicult to achieve with other plug–ins.
6) Acoustical issues are oen an annoyance at low frequencies. RSPhase-
Shier lets you compensate for time delays between main speakers
and subwoofer channels…
a) Reduce the inuence of standing waves, or room modes, for a
loudspeaker setup in conjunction with one or more subwoofers.
b) Reduce the acoustical energy caused by low frequency cancella-
tion in live sound applications.
Stereo Track Caveats
In most stereo use cases, it makes sense to adjust the phase of just one
of two stereo channels. For that reason, in stereo you get one mono
instance on the right channel as a starting point, with the unaltered le
channel shown with its cover plate. When you want to use the MAAT
RS Phase Shier on the le channel, just press the FLIP button. If you
want to apply phase shi to both channels equally, use MIRROR mode.
Note that, normally, you cannot have oset control settings in MIR-
ROR mode; the same settings are applied to both channels. By control–
clicking on MIRROR, the two sets of controls are unlinked, operating
independently.
You may be asking yourself, “How can I have dierent treatment for
le and right channels?” In most cases, that simply doesn’t make sense
and you’d have a good chance of getting lost in your plug–in setup.
at said, unlinking via control–clicking MIRROR as mentioned above
would do the trick. You would need that function if the stereo channel
you are working on has:
a) an internal phase problem to be cured and
b) a phase problem in relation to another channel or stereo pair
To prevent you from getting lost in nding the best phase settings, we
recommend that you not unlink, and instead rst use a plug–in instance
with just one side in use, either le or right, to adjust the internal phase
relation between the two. When you’re done, just open another plug–in
instance and switch that instance to MIRROR mode. Now you can nd
the proper phase relation in conjunction with other tracks by shiing
the phase of the le and right channel, always with the same phase rota-
tion so that you can’t mess up the correct internal phase relation set by
the rst instance. is is much faster and allows individual A/B-ing of
both steps of phase correction.
e unlink mode is useful when using RSPhaseShier in an MS work-
ow where you want to create special eects. We have added this option
to make it available to you geeks, you know who you are, who simply
can’t resist going one step further.
