Ambisonics
The Ambisonics DSP preset can decode UHJ format, the two- channel
Ambisonics 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 soundfield exactly at that position. The microphone signals are then encoded using a
The digital surround controller uses accurately matched, frequency- dependent,
Ambisonics and Super DSP preset parameters
The fundamental difference between Ambisonics surround sound and conventional stereo is that the signals from all the speakers combine to produce a coherent soundfield 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
Super
Super 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.
