Abstract
Provided is an audio signal processing apparatus including: a first buffer configured to temporarily store an audio signal; a feedback path whose start point and end point are located close to an output side of the first buffer; and a second buffer connected in the feedback path and configured to temporarily store the audio signal.
Claims7
An audio signal processing apparatus comprising:
- a first buffer configured to temporarily store an audio signal;
- a feedback path whose start point and end point are located on an output side of the first buffer;
- a second buffer connected in the feedback path and configured to temporarily store the audio signal;
- and
- a gate connected to the output side of the first buffer and not connected in the feedback path,
- wherein the gate is turned on when a predetermined trigger operation is performed and is turned off when the audio signal of a predetermined time length is transmitted.
An audio signal processing method comprising:
- temporarily storing an inputted audio signal in a first buffer;
- turning on a gate connected to an output side of the first buffer to output the audio signal stored in the first buffer and temporarily store the outputted audio signal in a second buffer;
- turning off the gate when the audio signal of a predetermined time length is transmitted;
- and
- outputting the audio signal stored in the second buffer and feeding back the audio signal to the second buffer.
A non-transitory tangible recording medium recording a program configured to cause a computer to function as an audio signal processing apparatus comprising:
- a first buffer configured to temporarily store an audio signal;
- a feedback path whose start point and end point are located on an output side of the first buffer;
- a second buffer connected in the feedback path and configured to temporarily store the audio signal;
- and
- a gate connected to the output side of the first buffer and not connected in the feedback path,
- wherein the gate is turned on when a predetermined trigger operation is performed and is turned off when the audio signal of a predetermined time length is transmitted.
