Device and method for analyzing and representing sound signals in the musical notation

A sound signal analyzing device comprising:

• an input section that receives sound signals to be analyzed;
• a characteristic extraction section that extracts a pitch of a sound signal as it is received by said input section;
• a designating section that, based on the pitch of the sound signal, designates at least one of an upper and lower pitch limit as a pitch limit characteristic;
• a setting section that sets various parameters for use in subsequent analysis of sound signals received by said input section in accordance with the pitch limit characteristic, including at least a filter characteristic;
• and
• a display section that visually displays the pitch limit characteristic by displaying an image indicative of at least one of the upper and lower pitch limits,
• wherein a user can vary the pitch limit characteristic by manipulating the image such that the setting section sets the various parameters in accordance with the varied pitch limit characteristic.

A sound signal analyzing method comprising the steps of:

• receiving sound signals to be analyzed;
• extracting a volume level of the sound signal as it is received by said step of receiving;
