Part 5. Extended Knowledge on MP3 Files to WAV Conversion

At the starting of this article, we have already discussed the most common reasons why people prefer to convert MP3 audio files to WAV format. We know that MP3 is a lossy compressed file, converting it to WAV will not help regain the full resolution that initially existed. MP3 file compression is a destructive compression with permanent changes and data loss, which is decided by the compression algorithm. Once compressed, the original file cannot be recreated or rebuild, even if it is uncompressed through WAV format. Here, it needs to be well understood that whatever imperfections in the MP3 file will remain there even after converting it to WAV, but will surely not worsen.
