Transcribe a fileWhat AAC actually is
AAC is a lossy audio codec, the default on Apple devices and across most streaming. It is the successor to MP3 and packs the same quality into a smaller file. You will find it inside M4A containers, in streamed audio, and in the soundtrack of most video.
AAC is lossy, but it is clear for speech even at modest bitrates, since the compression keeps the frequencies a voice lives in. You do not need to convert it yourself: drop the file and Typist handles the rest, transcoding it before transcription so you never have to think about the codec. As with every format, the recording sets the ceiling. Clean, close-mic speech transcribes near 99%, noisy audio less.
