Simply put, transduction is the process of converting one type of energy to another. For audio-specific purposes, if you’ve ever used a microphone or a speaker to record or amplify a sound, you’ve seen transduction in action.
A microphone works as a transducer by changing acoustic waves to electrical waves. And a loudspeaker is also a transducer, even though it does the opposite: by changing electrical waves to acoustic waves.
