Abstract: To satisfactorily perform processing of increasing the sound quality of a recorded sound source obtained by picking up vocal sound and musical instrument sound in a room. An output audio signal is obtained by a sound converter performing sound conversion processing on a recorded sound source (an input audio signal) obtained by picking up vocal sound or musical instrument sound by using any microphone in any room. The sound conversion processing includes processing of removing room reverberation from the recorded sound source, processing of remove picked-up sound noise from the recorded sound source, processing of including target microphone characteristics into the recorded sound source, and processing of including the target studio characteristics into the recorded sound source.

Abstract: When an electronic mail is transmitted, a computer outputs to a display device a transmission confirmation screen on which a destination or an attached file name is displayed, the destination or the attached file name being different from a destination or an attached file name that has been set by a user in the electronic mail, and on which whether transmission of the electronic mail will be performed is selectable. Upon receipt of selection of whether the transmission will be performed, the computer outputs to the display device message information that varies according to a result of the selection of whether the transmission will be performed on the transmission confirmation screen.
