Abstract

A recording and playback device according to the present invention stores in a memory section sound data for an amount of time corresponding to a beat which is acquired from an external source, and creates loop sound data in bar units by connecting a plurality of stored sound data. Then, the recording and playback device performs an operation to overlap newly acquired sound data onto the loop sound data while the loop sound data is being repeatedly replayed, and store the overlapping sound data in the memory section.

First claim

What is claimed is:

1. A recording and playback device comprising:
a memory; and
a controller which is configured to:
store in the memory first sound data having a length corresponding to a beat among sound data acquired from an external source;
create a plurality of pieces of copied sound data from the first sound data, such that a number of the created pieces of the copied sound data is based on a specified meter, connect one of the plurality of pieces of copied sound data to another of the plurality of pieces of copied sound data to create loop sound data of at least one bar, and store the loop sound data in the memory;
repeatedly replay the loop sound data stored in the memory; and
perform an operation to overlap sound data acquired during replaying of the loop sound data onto the loop sound data being replayed, and store the overlapping sound data in the memory.

2. The recording and playback device according to claim 1 , wherein the controller is further configured to:
set a recording time for the beat based on a specified tempo and the specified meter; and
perform an operation to record inputted sound data in the memory from a time when sound data exceeding a threshold value is inputted until a time when the set recording time elapses.

3. A non-transitory computer-readable storage medium having stored thereon a program that is executable by a computer used in a musical sound playback device, the program being executable by the computer to perform functions comprising:
storing in a memory first sound data having a length corresponding to a beat among sound data acquired from an external source;
creating a plurality of pieces of copied sound data from the first sound data, such that a number of the created pieces of the copied sound data is based on a specified meter, connecting one of the plurality of pieces of copied sound data to another of the plurality of pieces of copied sound data to create loop sound data of at least one bar, and storing the loop sound data in the memory;
repeatedly replaying the loop sound data stored in the memory; and
performing an operation to overlap sound data acquired during replaying of the loop sound data onto the loop sound data being replayed, and storing the overlapping sound data in the memory.

4. A musical sound playback method comprising:
storing in a memory first sound data having a length corresponding to a beat among sound data acquired from an external source;
creating a plurality of pieces of copied sound data from the first sound data, such that a number of the created pieces of the copied sound data is based on a specified meter, connecting one of the plurality of pieces of copied sound data to another of the plurality of pieces of copied sound data to create loop sound data of at least one bar, and storing the loop sound data in the memory;
repeatedly replaying the loop sound data stored in the memory; and
performing an operation to overlap sound data acquired during replaying of the loop sound data onto the loop sound data being replayed, and storing the overlapping sound data in the memory.

5. The non-transitory computer-readable storage medium according to claim 3 , the functions further comprising:
setting a recording time for the beat based on a specified tempo and the specified meter; and
performing an operation to record inputted sound data in the memory from a time when sound data exceeding a threshold value is inputted until a time when the set recording time elapses.

6. The method according to claim 4 , further comprising:
setting a recording time for the beat based on a specified tempo and the specified meter; and
performing an operation to record inputted sound data in the memory from a time when sound data exceeding a threshold value is inputted until a time when the set recording time elapses.

7. The device according to claim 1 , wherein the plurality of pieces of copied sound data are created such that the number of the created pieces of the copied sound data is equal to a number of beats in the specified meter.

8. The non-transitory computer-readable storage medium according to claim 3 , wherein the plurality of pieces of copied sound data are created such that the number of the created pieces of the copied sound data is equal to a number of beats in the specified meter.

9. The method according to claim 4 , wherein the plurality of pieces of copied sound data are created such that the number of the created pieces of the copied sound data is equal to a number of beats in the specified meter.
