I have a large collection of music library and the files are in different formats, such as mp3, wav, flac and m4a. What is the best way to join multiple small audio files into a big one?

Tried three online audio joiners but none of them worked. They told me the codecs not supported. Could anyone recommend a good audio joiner to be used on Windows 10 or share step-by-step instructions on how to merge audio files?
