Nugen Audio HaloVision (Digital product)

Customizable surround audio analysis

Comprehensive analysis for 3D and immersive audio; Halo Vision is a customizable, real-time visual analysis suite. A variety of modules provide audio professionals with a clearer understanding of every aspect of their audio, allowing for precise and confident decision making and troubleshooting, and pinpointing problem areas which might be missed using ears alone.

The Correlation Matrix displays colour-coded phase relationships between every channel, with a larger arched meter for more detailed analysis, and anti-correlation alerts at a user-defined threshold.

The Correlation Web shows a network of channels with an interconnecting line between each pair. When the phase relationship between two channels becomes anti-correlated, the corresponding line lights up.

Both of these views use Contextual Correlation by default. Standard calculations used by other correlation meters are normalised in such a way that two signals might appear to be highly anti-correlated, even if one signal is so much louder or quieter than the other that mixing them together will not cause phase cancellation. Contextual Correlation compensates for these level differences, only highlighting correlation issues which are likely to cause a problem.

Haze views

With low frequencies at the centre and high frequencies on the outer edge, the circular Frequency Haze displays frequency content across the surround field, with channel labels in typical speaker positions.

The Location Haze provides a visualization of the perceived location of your audio, showing energy distribution across the surround field, with brighter sections indicating increased “energy”.

Other views

In ‘Combined’ mode, the Spectrum view displays an FFT level-against-frequency graph for all the channels in one spectrum. In ‘Groups’ mode, channels can be organised into groups of spectrums.

True Peak view provides a True Peak dB level meter for each channel.

The Timecode view displays a timecode readout based on the current host/DAW playback position.
