Conversion of MP3 to WAV with saving the quality

The WAV/PCM is a lossless format, while MP3 is not. So, if you convert MP3 to WAV/PCM, you get whatever imperfections existed in the MP3, meaning the WAV won't get better. However, it is possible to avoid getting it worse.

When converting a music MP3, the default settings would do just fine to save the quality. That is, WAV Codec set to 'Automatic Selection.' To preserve quality, it is also essential to avoid resampling and remixing. Sample Rate and Channels should be 'As Source.'
