What is the name of a device that converts sound waves to electrical waves ?
a microphone
a microphone option is correct.
A microphone is an electro-acoustic transducer that converts sound-pressure waves striking its diaphragm into a proportional electrical signal, using dynamic, condenser, ribbon, piezoelectric or MEMS principles. It is the input transducer for every audio recording, telephony and speech-recognition chain.
An amplifier only raises the level of an already-electrical signal; a recorder stores a signal after conversion; a filter shapes the spectrum of an electrical signal. None of these performs the sound-to-electricity conversion itself.
