Ambisonic

The Ambisonic DSP preset is designed for replaying material encoded in UHJ format, the two-channel stereo-compatible encoding found on Ambisonically-recorded discs and broadcasts. This material is specifically encoded for surround reproduction and can give breathtakingly realistic sound when replayed using the digital surround processor.

Ambisonic surround sound is quite unlike conventional stereo. A special microphone technique picks up the sound of the original performance in all three dimensions, allowing an archive to be made which describes the sound field exactly at that position. The microphone signals are then encoded using a phase- amplitude matrix to allow the effect to be conveyed on two- channel carriers (like FM radio, LP, or CD).

The digital surround processor uses accurately matched, frequency-dependent, phase-amplitude matrices to decode the signal and construct the signals for each speaker feed.

The fundamental difference between Ambisonic surround sound and conventional stereo is that the signals from all the speakers combine to produce a coherent sound field at the listening position, giving the illusion that you are sitting inside the

recording space whether you are at the exact central seat or well off to one side.

Of all the signal-processing options, Ambisonic is the one that requires the greatest attention to speaker choice and positioning.

Super Stereo

Super Stereo synthesises a signal from a conventional stereo recording or broadcast so that it can be decoded using the Ambisonic decoder. The result is especially effective for two particular types of recordings:

Those using true coincident microphone techniques.

Multi-tracked or multi-miked recordings.
