sound design project total 2 sample sounds.
we have a piezo driver based device. we needed a design of several sound effects for this device. driver first resonance frequency is about 1150-1200 hz. it is some kind of alarm device 44100 khz mono and 16 bit file.
as you can see almost all sound has frequency sweep in a band. it is because the piezo driver resonance frequency is not certain and to catch resonance sound effect must sweep in a range.
