Demos

Several types of demonstration tracks are provided below. The full benefits of Ambiophonics can only be realized when a home user has access to all the adjustments provided in RACE equipped systems.

2 Channel

These demonstrations are samples of music and sound culled from ordinary commercially available CDs. Normally the RACE program is installed in a home preamp, surround processor, or PC, so that it can be adjusted to taste and used to reproduce your existing collection of CDs, LPs, or surround DVD/SACDs Ambiophonically rather than stereophonically.  In stereo, the stage is limited to the angle between the speakers.  In 2 speaker Ambiophonics the stage can extend beyond the speakers to widths of 150 to 180 degrees or more depending on the recording.  In 4 speaker Panambiophonics a full 360 degree circle of sound can be heard in movies, games, etc.   

Speakers should be about 20 degrees apart or about one third as much apart as they are in stereo.  Alternatively, if you do not want to move your speakers you can just move back from them until the apparent angle is one third narrower. Use any track to adjust your own or the speaker’s positions until you hear the sounds from as far to the sides as possible or somewhat less if your preference is for a narrower stage.  Move forward and back to get the range of the effect (normally many feet) and then start listening at the middle of this range.  At this point you should be able to move about, stand, recline, rotate, and nod without any more change than in a concert hall.  If you cannot achieve such a spread symmetrically to your left and right it may be that your speakers or vacuum tube amplifiers are not in balance.  Ambiophonics programs and components have controls to allow one to adjust them for optimum performance with any PC/component home system, recording or individual hearing characteristics. You can quickly compare Ambiophonic sound to stereophonic sound by moving toward the speakers until the normal 60 degree angle is again approximated.

These are short tracks culled from a variety of ordinary cds made using a variety of microphone and recording techniques.

 

2 Channel Ambiophone

This demonstration disc contains samples of music recorded using the Ambiophone, a microphone designed to deliver exceptional fidelity when processed, in playback, by a new type of digital audio program that allows these and most other two channel recordings to be played with unprecedented stage width, depth and binaural realism by reproducing all the localization cues inherent in CDs and LPs but lost when reproduced using the stereo loudspeaker triangle.  Normally the RACE program is installed in a home preamp, surround processor, or PC, so that it can be adjusted to taste and used to reproduce your existing collection of CDs, LPs, or surround DVD/SACDs, Ambiophonically rather than stereophonically.  In stereo, the stage is limited to the angle between the speakers.  In 2 speaker Ambiophonics the stage can extend beyond the speakers to widths of 150 to 180 degrees depending on the recording.  In 4 speaker Panambiophonics a full 360 degree circle of sound can be heard in movies, etc.  

Speakers should be about 23 degrees apart or about one third as much apart as they are in stereo.  Alternatively, if you do not want to move your speakers you can just move back from them until the angle is about one third narrower. Use any track to adjust your own or the speaker’s positions until you hear the sounds from as far to the sides as possible or somewhat less if your preference is for a narrower stage.  Move forward and back to get the range of the effect (normally many feet) and then start listening at the middle of this range.  At this point you should be able to move about, stand, recline, rotate, and nod without any more change than in a concert hall.  If you cannot achieve such a spread symmetrically to your left and right it may be that your speakers or vacuum tube amplifiers are not in balance. Ambiophonics programs and components have controls to allow one to adjust them for optimum performance with any PC/component home system, recording or individual hearing characteristics.

You can quickly compare Ambiophonic sound to stereophonic sound by moving toward the speakers until the normal 60 degree angle is again approximated.  However, these tracks will sound strange if played back at the normal stereo speaker angle of 60 degrees because instead of cancelling the stereo crosstalk you will be enhancing it.

The unprocessed .wav files in the table below are also provided for users who have RACE installed and wish to optimize the reproduction of these and their own disks. These samples were recorded using the Ambiophone by Robin Miller, of Filmmaker.

DTS

For those wanting to try 4.0 Pan Ambiophonic 360 degree surround sound, this set of .wav files is provided. These are 44.1 DTS encoded 4-channel recordings. You can download and make a DTS encoded cd from them to play back in a home theater system equipped with a RACE 4-channel decoder.
