I have a large collection of audio files in different formats (like WAV, FLAC, AAC, and MP3), and I need to convert them all into a single format for easier playback and management. Doing it one by one is too time-consuming. Can anyone suggest a reliable audio converter tool that supports bulk or batch audio file conversion without losing sound quality? I am also looking for something that works efficiently on Windows (bonus if it is free or has a trial version).
