Decompress audio for editing or studio use
WAV is the reference format in audio production (editing, mixing, sound design) because it introduces no compression, unlike MP3. Some professional software expects a WAV file as input to guarantee a processing chain with no additional degradation.
The resulting file is much heavier, with no quality gain
Converting an MP3 to WAV doesn’t restore audio data already removed by the original MP3 compression: the WAV file is simply larger (typically 5 to 10 times), being uncompressed, with no audible quality improvement.
Required by some devices and software that don’t read MP3
Some professional audio equipment, embedded systems, or sound-analysis software only accept WAV as input: this conversion meets that technical requirement rather than a quality need.
