Voxengo – PHA-979 2.7 VST, VST3, AAX, AU WIN.OSX x86 x64
PHA-979 2.7 is the latest version of the plugin that was released in May 2019. It features several improvements and enhancements, such as:
Added horizontal lining to correlometer.
Added Retina support on macOS, and automatic high-resolution UI size adjustment on Windows.
6% lower CPU usage on AVX2-capable processors (in 64-bit mode).
But what makes PHA-979 2.7 so special? Let's take a look at some of its features and benefits.
Arbitrary Signal Phase Control
PHA-979 2.7 allows you to apply an arbitrary phase shift to sound material. What is meant by the phase shift here is simultaneous rotation of all frequencies across the active frequency range of the signal by the given value in degrees. This is achieved by linear-phase design.
This feature is useful during mixing sessions, especially when working with the sound material recorded through an array of microphones. In many cases this allows you to solve various phasing problems arising from the microphone placement chosen during the tracking session. In other cases this process may help you to align drums and other instruments to each other bringing punch and time coherence not attainable by the ordinary time-aligning alone.
Positive and Negative Time Delaying
PHA-979 2.7 also features positive and negative time delaying that eliminates the need to move in-track events in the sequencer when doing time alignment over any set of recorded tracks. You can use the delay time calculator to easily set the desired delay value based on the tempo and note length.
This feature is also helpful for creating various effects such as doubling, flanging, chorus, etc.
Mid/Side Channel Balance and Panning Controls
PHA-979 2.7 provides mid/side channel balance and panning controls that permit you to record stereo microphone pairs into a single stereo track without resorting to dual mono recording (on separate tracks) which usually becomes time-consuming in a further editing.
This feature is also useful for adjusting the stereo width and balance of any stereo track or bus.
Multi-Band Correlation Meter
PHA-979 2.7 features multi-band analog-style correlation meter that greatly simplifies phase- and time-aligning process. It shows you how well the left and right channels of your signal are correlated across different frequency bands.
This feature helps you to avoid phase cancellation issues and achieve a better stereo image.
Headphone Monitoring Setup
PHA-979 2.7 also allows you to use its functionality to setup headphone monitoring so that it closer resembles sound stage produced by stereo speaker monitoring. You can use the phase rotator, stereo panner, and stereo balance meter to adjust the sound in your headphones according to your preferences.
This feature helps you to get a more realistic and accurate monitoring experience when using headphones.
How to Use PHA-979 2.7
PHA-979 2.7 is easy to use and intuitive. You can simply insert it on any track or bus that you want to process, and adjust the parameters according to your needs. Here are some of the main parameters and what they do:
Phase: This knob allows you to set the amount of phase shift in degrees. You can use positive or negative values to rotate the phase clockwise or counterclockwise.
Delay: This knob allows you to set the amount of time delay in milliseconds. You can use positive or negative values to delay or advance the signal.
Mid/Side: This switch allows you to choose between mid/side or left/right processing mode. In mid/side mode, you can adjust the balance and panning of the mid and side channels separately.
Balance: This knob allows you to adjust the balance between the left and right channels (in left/right mode) or the mid and side channels (in mid/side mode).
Pan: This knob allows you to adjust the panning of the stereo signal (in left/right mode) or the width of the mid/side signal (in mid/side mode).
Corr: This meter shows you the correlation between the left and right channels across different frequency bands. The green bars indicate positive correlation, while the red bars indicate negative correlation. You want to avoid negative correlation as much as possible, as it can cause phase cancellation and loss of stereo image.
You can also use the presets menu to choose from some common settings for different applications, such as drum overheads, guitar cabinets, vocal groups, etc.

PHA-979 2.7 has received many positive feedbacks and testimonials from users who have tried it and loved it. Here are some of them:
\"I must add a review to point out that this plug-in has more uses than at first meets the eye. You may use it to construct a Dolby ProLogic (r) encoder so that your stereo material is compatible with all the Hi-Fi amps, televisions, game consoles that provide surround sound from a two channel delivery format. ... This plug-in is the only one (and I've tested a lot!) that actually offers a true 90 degrees phase shift across the frequency range and that works as a surround encoder. The quality of the sound is pristine, and I'm happy to have found this gem!\" - Paal Rasmussen, sound engineer
\"In a market saturated by modeled plugins and 'unique concept' plugins, Voxengo continues to maintain a niche right in the middle. Their plugins are functional, stable, easy to work with and have a natural organic sound. ... The PHA-979 is a an excellent example: it is a phase and time correction plugin - the kind of tool one uses to reduce or eliminate phase cancellation between microphones or other problematic multi-channel sources. But PHA-979 is not like other phase correction plugins. For one thing, it is Linear Phase, which means that phase adjustments are equal across the spectrum; LP rotation makes it possible to correct phase cancellations across the frequency spectrum, unlike 'analog' (minimum phase) tools, which typically force a compromise.\" - Voxengo user
\"Been using these for about 6 years and I wanted to express how much I appreciate them. HarmoniEQ is such an asset to adding color. In the tradition of the Pultec EQP-1 I often bring frequencies down with the stock Reaper EQ and bring them back up with HarmoniEQ, adding color when I don't even need an EQ adjustment. ... The bass saturation feature in LF Max Punch gets so much use, even on vocals to give them a \\\"closer\\\" feel to them, on overheads and ambient mics to get more room impact on the lows, places I never would have thought to use them. Brilliant tool! Elephant is the only remotely pumpy limiter I'll use. ... Here's some pearls for folks who don't appreciate how awesome a phase adjustment tool PHA-979 is. Any recording that's live or live off the floor with ambient mics, you can use PHA-979 to phase-align direct mics to the ambient mics by adjusting the phase so the lower frequencies combine the most ... Then put a PHA-979 on an aux bus with L/R set to -90/+90, to generate a side channel. Mute the ambient mics and send all your direct mics through that side channel bus and feather it up until you can barely notice the widening effect. Now unmute the ambient mics, and you can't tell where they end and the direct mics begin.\" - Voxengo user
