Answer:
by converting the electronic signals back into sound waves
Step-by-step explanation:
When sound is recorded then we convert the sound energy into electrical energy and store it on the magnetic tapes
Now when we have to convert this energy again into sound then we use the reverse phenomenon.
So in this reverse phenomenon we have to convert the electrical energy stored on the magnetic tapes into the sound energy so overall we can say that correct answer will be
