ABSTRACT:
A sound capturing method and device for use in making recordings having improved three-dimensional imagery during playback. Vibration information is detected from a body portion through the use of a crystal microphone for generating a first signal corresponding to a vibrational frequency of the body portion in response to a received sound wave. Direct sound information is detected from the body portion through the use of a condenser microphone affixed thereto at a second location for generating a second signal corresponding to a frequency of the received sound wave. The first and second locations are in proximity to one another such that a sound wave will reach each location at substantially the same time. Alternatively, the signals received at either location may be processed or time-delayed such that sound waves are recorded from each location at substantially the same time. The resultant first and second signals may be combined through the use of a mixer and then put into a conventional sound recording device.
