Abstract
Disclosed are a tone converter and a tone converting method employed in a process of playing music, voice, and an audio signal. The tone converter includes at least one delayer for generating an echo pulse by delaying an input audio signal for a predetermined time, a multiplier for multiplying a time delay value of the echo pulse outputted from a corresponding delayer by a gain value, and an adder for adding an echo signal outputted from the multiplier to the input audio signal so as to output a tone converted audio signal.
Claims11
A tone converter, comprising:
- at least one delayer for generating an echo pulse by delaying an input audio signal for a predetermined time;
- a multiplier for multiplying a time delay value of the echo pulse outputted from a corresponding delayer by a gain value;
- and
- an adder for adding an echo signal outputted from the multiplier to the input audio signal so as to output a tone converted audio signal.
A tone converter, comprising:
- a first delayer for generating a first echo pulse by delaying an input audio signal for a predetermined time;
- a first multiplier for multiplying a time delay value of the first echo pulse outputted from the first delayer by a gain value of the first echo pulse;
- a second delayer for generating a second echo pulse by delaying an audio signal outputted from the first delayer for a predetermined time;
- a second multiplier for multiplying a time delay value of the first echo pulse outputted from the first delayer by a gain value of the first echo pulse;
- and
- an adder for adding an echo signal outputted from the multiplier to the input audio signal so as to output tone converted audio signal.
An audio signal converting method of a tone converter comprising at least one delayer and multiplier, and an adder, the method comprising the steps of:
- inputting the audio signal;
- delaying the input audio signal for a predetermined time so as to generate the echo pulse;
- multiplying a time delay value of the echo pulse by a gain value of the echo pulse;
- and
- adding the multiplied echo signal and the input audio signal so as to output a tone converted audio signal.
