Audio can contain dial tones, or it can contain binary/morse code on some particular frequency, or it's not really "audio" but radio-transmission which needs to be decoded, or the audio can contain sounds of keyboard typing or even 3d printer head moving (like https://github.com/p4-team/ctf/tree/master/2020-05-10-spam-and-flags-teaser/3d_printer ), or maybe audio has multiple sources interleaved and you need to separate them and one has the flag, or maybe the audio file itself has specific format and some information can be passed there. There are infinite possibilities and it's impossible to say anything without analysing the file.
