Which file extension indicates that the file is an audio clip?

The file extension .wav indicates that the file is an audio clip. This format is known as Waveform Audio File Format, which was developed by Microsoft and IBM. It is widely used for storing audio on PCs and can handle high-quality sounds, making it a popular choice for audio recording and editing applications.

In context, .mp3 is another common audio format, known for its compression capabilities, which allow for easier storage and streaming of music files while sacrificing some audio quality. .mp4 is primarily a video file extension that can also contain audio, often used for video playback. Similarly, .avi is a video file format that can contain audio as well, but it is not specifically designated for audio clips alone. Therefore, while .mp3 can also indicate an audio file, .wav is distinctly recognized for high-quality audio.
