Is the sound quality different for each app on iPhone Xs Max?

iphone-xs-max recording

It seems like the recording quality is different between using voice memo on iPhone Xs Max and taking a video

It's the same microphone, but can the recording quality be different for each app?

I think it's because of the encoding difference

I think there's a difference in the sampling method
Even if the microphone is the same, the app will sample it anyway

I understand that voice notes use lossless compression, and videos are not lossless compression

The video is stereo, and the voice note is different from Mono

Voice note is Apple Lossless Lossless lossless codec, Mono, 48000Hz
The video is AAC Codec, Stereo, 44100Hz
Both of them are sampling vaguely, so it's hard to say which one is better
