Abstract: A sound signal processing system includes: a sound signal processing apparatus executing non-linear signal processing on a collected sound signal collected by a microphone, and transmitting, to an information processing apparatus, both a pre-execution sound signal before the non-linear signal processing is executed and a post-execution sound signal after the non-linear signal processing is executed; and the information processing apparatus receiving the pre-execution sound signal and the post-execution sound signal from the sound signal processing apparatus, and executing first processing on the pre-execution sound signal and executing second processing on the post-execution sound signal, the second processing being different from the first processing.

Abstract: A sound signal processing device that acquires a collected-sound signal obtained by sampling a sound collected by a microphone at a first sampling frequency, and receives a reproduced-sound signal obtained by sampling a sound for reproduction at a second sampling frequency different from the first sampling frequency, and then converts the sampling frequency of the reproduced-sound signal into the first sampling frequency so as to remove an acoustic echo from the collected-sound signal by using the reproduced-sound signal whose sampling frequency has been converted.
