Lossless when possible
Most MP4 and MOV videos store their sound as AAC. Choosing M4A copies that track as it is, so the audio file sounds exactly like the video and is ready almost instantly, even for a two hour recording. WAV converts the sound to uncompressed audio, ideal for editing in Audacity, GarageBand or a DAW. OGG with the Opus codec gives the smallest files for speech.
Use it to listen to lectures and webinars on the go, to cut a podcast from a video call recording, or to pass the voice track of an interview to a transcription service.
Your recordings stay private
