Stereo Position Display (SPD)

The SPD shows you the stereo energy in your mix, clearly and intuitively. This unique audio meter analyzes the distribution of loudness across the stereo stage, as well as detecting out-of-phase components. It differs from the common ‘phase display’ where left/right channels are displayed against each other on a oscilloscope screen.

For those familiar with the Waves S1 Stereo Imager, the Stereo Position Display will seem familiar, as both use a polar coordinates graph. Loudness is shown by length of the line and stereo position is shown by the angle (direc- tion). The concentric lines are 20dB step indications.

In other words, a mono signal goes straight up (as will anything in the center of a stereo mix). A hard left or right sound will go 45 degrees to the respective sides. Most stereo mixes will have a fan-shaped display centered around the vertical line with occasional little spikes shooting out at greater angles.

Out-of-phase signals are shown between 45 and 90 degrees on each side. In the area beyond 60 degrees on each side have a red color in the background to indicate that signals in this range might be disturbing to the ears.

The controls

They are the same for the SPD as for the Frequency Display, except that when using the component Frequency plug- in, only the related controls are shown.

About Anti-phase

It is a bit tricky to define when a signal is shown by the Stereo Position Display or heard by the ears as “out-of-phase”. This is not simply when the left and right channels happen to have opposite polarity at any given instant. Such a situation can happen if independent instruments are panned to different stereo positions, and it just happens, statistically, that the signal of each channel has opposite polarities. The meter will show a quick spike in the anti- phase area. This can also happen if a stereo delay or reverb is applied to an instrument and the delays arrive to each

Users can visualize audio frequencies in real-time, providing an intuitive understanding of how sound behaves across different ranges. The high-resolution spectrum analyzer grants detailed insights into the frequency content of audio signals, which is invaluable for tasks like mastering and mixing.

In addition to spectrum analysis, Waves PAZ incorporates a phase correlation meter, which is essential for stereo imaging. This tool allows users to monitor the phase relationship between left and right channels, helping to avoid phase cancellation issues that can negatively impact the listening experience. The ability to assess stereo width and depth is crucial for achieving professional quality mixes and ensuring that audio translates well across various playback systems.

The intelligent loudness meter is another integral feature of Waves PAZ. It adheres to industry standards, providing precise measurements of loudness in accordance with standards such as EBU R128, and ITU-R BS.1770. This ensures that audio levels are compliant and optimized for broadcasting and streaming, maintaining sonic consistency across different platforms.

Waves PAZ is built on proprietary algorithms that deliver accuracy and speed without compromising on quality. Its user-friendly interface simplifies complex audio analysis, allowing users to focus on creativity rather than technical hurdles. The software is compatible with major digital audio workstations (DAWs), making it versatile and accessible for a wide range of users.

Moreover, Waves PAZ is designed with real-time performance in mind, enabling users to monitor their audio while working on projects without any noticeable latency. This is crucial for live sound applications and precise studio work where timing is everything.

Overall, Waves PAZ stands out as an essential tool for audio professionals, combining powerful analysis features with advanced technologies designed to elevate the quality of sound production. Its comprehensive capabilities make it a go-to choice for anyone looking to enhance their audio engineering skills. With continuous updates and improvements, Waves PAZ helps users stay at the forefront of sound technology, ensuring they can create the highest quality audio possible.
