Abstract

An interactive and programmable tone generator with scenarios is disclosednd described as a training device. Sounds are recorded as they are heard in their actual environment. The recording then can be combined with a coded track that triggers a graphics demonstration previously prepared from notations taken during the recordings that describe the actual environment that corresponds to the respective sound. Also, selections can be taken from the recording that present a best example of a sound to be learned, looped for repetition, and then rerecorded digitally onto micro-floppy diskettes. When played-back the diskettes provide challenging interactive training for the novice and expert alike in a variety of available modes using both computer generated graphics and sounds reconverted from digital storage.

Claims

1. Apparatus that provides sound related training by using sounds that have been recorded in the environment in which they occur, to school trainees in the direction, identification and interpretation of sounds that in their environment normally do not occur enough to be reliably used for training, or if they do occur enough, the environment in which they occur is not convenient for training, comprising:

a recording of sequential sounds;

means for indexing said sounds by digitally recording samples of said sounds in temporary storage;

means for subsequently detecting selected sounds by their indexes and presenting in response thereto a graphical display that corresponds to the indexes, comprising a programmed processor; and

,

means for providing an audible output of the selected sounds;

such that the graphical display presented corresponds to the sounds provided.

2. The apparatus of claim 1 wherein said indexing means further comprises means for permanently storing said samples.

3. The apparatus of claim 2 wherein said indexing means comprises an analog-to-digital converting multi-sampler device having internal temporary digital storage, disk drive and diskette based external permanent digital storage, and a digital-to-analog converting output.

4. The apparatus of claim 3 wherein said indexing means further comprises a dual channel audio tape recorder interfaced to said processor.

5. The apparatus of claim 4 wherein said sequentially recorded sound is on a first track of a stereophonic tape, and indexing is by an encoded signal generated by said processor and recorded on the second track of said stereophonic tape.

6. The apparatus of claim 5 whrein said processor is responsive to programs selectable from more than one mode.

7. The apparatus of claim 6 wherein the modes include a demonstration mode wherein at least one previously programmed scenario of dynamic graphics is presented by said processor in response to said encoded signal on said second track of said tape to correspond with sounds provided by the first track of said tape.

8. The apparatus of claim 7 wherein the modes include an interactive mode using digital storage of preselected sounds in said multi-sampler, and digital storage of previously prepared corresponding graphics in said processor, and wherein said processor further includes an input device to which it responds to control said multi-sampler and said graphics in accordance with said program to vary the sounds and display for interactive simulation.

9. The apparatus of claim 8 wherein said modes are selectable with said input device from a set of menus on the display, including a main menu for selecting a tutorial for operating the apparatus, a tutorial for operating the equipment about which said sequentially recorded sound is associated, a sub-menu for selecting at least one demonstration scenario in which said stereophonic tape is used, and at least one sub-menu for selecting at least one synthesized scenario in which said multi-sampler is used.
