Yes — I-AIFF yi-big-endian PCM apho i-WAV incinci-endian; isandi silingana, kwaye ukhetho luyimfuneko malunga nenkqubo ye-ecosystem evula ngaphandle kokukhathazeka. It is worth knowing before you overwrite an original you might need again.
Yintoni impazamo eqhelekileyo xa uxinzelela AIFF audio files?
