Abstract

An audio reproducer that can be preferably used to practice to play a musical instrument is disclosed. The audio reproducer includes an audio reproduction part and a processing part. The audio reproduction part reproduces a first audio signal recorded in a recording medium. The processing part performs a special reproduction operation on the reproduced first audio signal under control over the audio reproduction part as well as a special effect operation on a second audio signal supplied via an input terminal. Then the processing part synthesizes the resulting first audio signal and the resulting second audio signal to generate an output audio signal.

Claims

1. An audio reproducer, comprising:

an audio reproduction part reproducing a first audio signal recorded in a recording medium; and

a processing part performing a special reproduction operation on the reproduced first audio signal under control over the audio reproduction part as well as a special effect operation on a second audio signal supplied via an input terminal, synthesizing the resulting first audio signal and the resulting second audio signal to generate an output audio signal.

2. The audio reproducer as claimed in claim 1, further comprising an instruction part issuing to the processing part an instruction for the special reproduction operation together with a level of the special reproduction operation and/or an instruction for the special effect operation together with a level of the special effect operation.

3. The audio reproducer as claimed in claim 1, wherein the audio reproduction part and the processing part are integrally configured.

4. The audio reproducer as claimed in claim 1, wherein the audio reproduction part reproduces digital audio data from the recording medium, and the processing part digitally processes the digital audio data and performs the special reproduction operation on the digitally processed digital audio data.

5. The audio reproducer as claimed in claim 1, wherein the processing part detects a difference between a key of the second audio signal and a reference key.

6. The audio reproducer as claimed in claim 5, further comprising a display part displaying the difference between the key of the second audio signal and the reference key.

7. The audio reproducer as claimed in claim 1, further comprising an analog-digital converter converting an analog audio signal supplied via the input terminal into digital audio data.

8. The audio reproducer as claimed in claim 7, wherein the processing part digitally processes the digital audio data and performs the special effect operation on the digitally processed digital audio data.

9. The audio reproducer as claimed in claim 1, wherein the processing part digitally performs the special reproduction operation on the first audio signal to generate first digital audio data and the special effect operation on the second audio signal to generate second digital audio data, and digitally synthesizes the first and second digital audio data to generate a synthesized digital audio data.

10. The audio reproducer as claimed in claim 9, further comprising a digital-analog converter, in response to receipt of the synthesized digital audio data from the processing part, converting the synthesized digital audio data into an output analog audio signal.

11. The audio reproducer as claimed in claim 1, wherein the special reproduction operation includes at least one of a loop reproduction, a key change reproduction, a pitch change reproduction and a tempo change reproduction.

12. The audio reproducer as claimed in claim 1, wherein the audio reproduction part and the processing part are detachable each other.

13. The audio reproducer as claimed in claim 1, wherein the input terminal receives an audio signal generated by playing a musical instrument.
