What are two common audio file extensions?

.mp4 and .wav
.mp3 and .pdf
.mp3 and .wav
.avi and .mov

The correct answer is: .mp3 and .wav

The choice highlighting .mp3 and .wav as common audio file extensions is accurate due to the widespread usage and recognition of both formats in the audio industry. The .mp3 format is one of the most popular digital audio formats for music and sound files, known for its ability to compress audio while maintaining acceptable sound quality, making it ideal for online streaming and portable media devices. .wav, on the other hand, is a format typically used for uncompressed audio and is favored in professional audio settings because of its high quality and ability to preserve the original sound without loss. Together, these two extensions represent a significant portion of audio files found in various applications, from music streaming to audio editing, demonstrating their importance and commonality in audio technology.
