Abstract: An audio signal processing system for recording a sound inputted into a channel of a mixer which receives a plurality of audio signals, processes the audio signals in a plurality of channels and outputs the processed signals, and reproducing the recorded audio signal for adjusting parameters of the mixer is provided. The audio signal processing system records, when record is instructed a channel is selected, an audio signal inputted to the selected channel with relation information indicating the selected channel, and reproduces, when reproduction is instructed and a channel is selected, an audio signal which has been stored with relation information indicating the selected channel.

Abstract: In an automatic correction process, automatic correction processing portions 60 are connected to a set reference channel and target channels, respectively, so that test signals will be input to the automatic correction processing portions 60, respectively. A rise detection portion 60a detects a rise in a test signal input to a corresponding channel, so that a value counted by a sample counter 61 is latched by a latch 60b at the rising timing of this test signal. In accordance with a difference between the counted value latched to the reference channel and the counted value latched to the target channel, a time difference is calculated. In accordance with the time difference, a delay time set for a channel delay means of the target channel is automatically corrected.
