Audio converters are devices or software that change audio files from one format to another. For example, they can convert a WAV file into an MP3 format, making it easier to store and share. This is useful for ensuring compatibility with different devices, such as smartphones or computers. These converters can also adjust audio quality, allowing users to choose between high-fidelity sound and smaller file sizes. Many audio converters are available online or as downloadable applications, making them accessible for both casual users and professionals in the music industry.
