Questions tagged [sound-synthesis]

Periodic electric signals can be converted into sound by amplifying them and driving a loudspeaker with them. One way to do this is to simply add various amplitudes of the harmonics of a chosen pitch until the desired timbre is obtained, called additive synthesis. Another way is to start with geometric waves, which are rich in harmonic content, and filter the harmonics to produce a new sound- subtractive synthesis.
