Why Do Users Convert Audio Files?
Before jumping into the conversion methods, it helps to understand why these conversions are needed.

Professional editing
Studio recordings
Voiceovers
Podcasts
AAC and OPUS, being compressed, are not ideal for heavy editing.

MP3 strikes a balance between:
Good audio quality
Small file size
That is why OPUS is often converted to MP3.
4. Ease of Sharing
Not all platforms support AAC or OPUS, making conversion necessary for smoother uploads and distribution.
