Musical sound processing apparatus and musical sound processing method

A musical sound processing method, for an information processing apparatus to:

• generate a plurality of first signals in which at least one of a frequency characteristic and a time response of each of a plurality of processing unit signals obtained from a musical sound signal is modified;
• and
• generate a plurality of second signals in which at least one of a frequency characteristic and a time response of a noise signal associated with one or more first signals among the plurality of first signals is replaced with at least one of a frequency characteristic and a time response of the one or more first signals.

A non-transitory computer readable medium, storing a program being executed by a computer and causing the computer to execute:

• generating a plurality of first signals in which at least one of a frequency characteristic and a time response of each of a plurality of processing unit signals obtained from a musical sound signal is modified;
• and
• generating a plurality of second signals in which at least one of a frequency characteristic and a time response of a noise signal associated with one or more first signals among the plurality of first signals is replaced with at least one of a frequency characteristic and a time response of the one or more first signals.
