I. What are WAV and MP3 formats?

1. What is WAV format?

WAV, or Waveform Audio File Format, is an audio file format standard for storing waveform data, developed by IBM and Microsoft, with a .wav file extension. While WAV files can hold compressed audio, they typically contain uncompressed audio. Despite their large file size, uncompressed WAV files are favored by many radio broadcasters, including BBC Radio in the UK and Global Radio, the British commercial broadcaster.

2. What is MP3 format?

The MP3 format, a popular choice for digital audio coding, utilizes lossy compression to significantly reduce the size of audio files. Although this process involves the loss of some original data, a high-quality MP3 file can still preserve much of the original sound quality. This compression technique is not only advantageous for audio but is also employed for video and image files to help conserve storage space. For example, a 3-minute WAV file, which may be approximately 30MB, can be compressed into an MP3 file of just about 3MB, resulting in an impressive 90% reduction in size while still maintaining a considerable degree of audio fidelity.

After understanding what is WAV and MP3 format, let’s take a look at the method of converting WAV to MP3.
