Audio device and method having bypass function for effect change

A computer-implemented method for processing audio signals using an audio signal processor which is configured to process an original audio signal input thereto to impart at least one of various effects to the input audio signal and output the processed audio signal, the method comprising:

• an audio signal processing step of causing the audio signal processor to process an original audio signal input thereto to impart the at least one of various effects to the input audio signal;
• a bypass step of transferring the original audio signal without being processed by the audio signal processor;
• a gain adjustment step of performing gain adjustment for the original audio signals transferred through the bypass step;
• a gain setting step of setting a gain used for the gain adjustment performed by the gain adjustment step in accordance with a ratio of input and output signal levels of the audio signal processor;
• and
• a control step of selecting and outputting at least one of the audio signal processed by the audio signal processor and the audio signal having the gain adjusted by the gain adjustment step, and
• wherein the control step normally selects the audio signal processed by the audio signal processor, while the control step temporarily selects the audio signal having the gain adjusted by the gain adjustment step instead of the audio signal processed by the audio signal processor when the audio signal processor is given an effect change command.
