Audio program / ram correction method
3. Detailed Description of the Invention In the recent development of acoustic systems, much
effort has been devoted to creating devices that improve music and speech reproduction.
However, these efforts are generally directed at improving fidelity. I have been doing something
as similar as possible to live playing the sound of the moon. By completely modifying the original
progery material as desired, it has been found that a completely new and pleasing form of sound
reproduction takes place, which brings a new dimension to the hearing field. The object of the
invention is to give the listener a whole new kind of enjoyable musical experience. Another object
of the invention is to provide a system for correcting the recorded normal sound. is there. Yet
another object of the invention is to make the sound from a pair of spaced apart speakers come
from an apparent sound source that is either sounding from one of the speakers or from one to
another. And moving the sound source left and right between the speakers.
4. Brief Description of the Drawings FIG. 1 is a block diagram showing an apparatus for
reproducing sound according to an embodiment of the present invention. FIG. 2 is a circuit
diagram of a part of the device 4 shown in FIG. 3A and 6B show an embodiment of a signal
distributor which forms an integral part of the invention, the same being connected to the circuit
of FIG. FIG. 4A is a top view of an example of a mechanism for generating control signals used in
the circuit of FIG. FIG. 4B is a side view of the mechanism of FIG. 4A taken along line 4B-4B. FIG.
5 is a block diagram of another embodiment of the invention similar to that of FIG. 1 but having a
control signal selector which obtains control signals from a recording medium. 6A and 6B are
waveform diagrams that serve to illustrate the operation of the embodiment of the invention of
FIGS. 5 and 7; FIG. 7 (d shows an example of a control signal selector used in the apparatus of
FIG. FIG. 8 shows an example of a transistor distribution circuit which can be used in place of the
mechanical signal distributor shown in FIGS. 1 and 2 and in particular in detail in FIGS. 3A and
3B. FIG. 9 is a table of the potentials at each point in the circuit of FIG. 8 useful for explaining the
operation of the transistor distribution circuit shown in FIG. FIG. 10 shows another embodiment
of the present invention useful for each musical instrument. FIG. 11 is a block diagram of yet
another embodiment of the invention which includes preselected patterns and, accordingly,
means for varying the gain of the audio amplifier. In the figure, ten nirecord 12: pinocano Nop
