Is there any reason why iPhones dont record audio in stereo? Why do they record in mono only, is it because of just one speaker on the phone for playback?

The quality sounds good and clear but I notice some Android devices recording in stereo, they just sound a tad bit fuller

Here's a quiz:

How many microphones does it take to record in stereo?

How many microphones does the iPhone have?

:D

Ding ding ding.
We have a winner #
Stereo= 2 speakers.
iPhone has only 1 speaker.
He said microphones not speakers.
Also the iphone doesn't have only one mic like he stated. There is also one in between the camera and flash, and if the 6 is like the 5 then there would be one in the earpiece as well. This is in addition to the one on the bottom by the Lightning port. Although they aren't really setup in very good positions to record in stereo.

Okay, it's true there is more than one mic, but for good stereo recording, you need two MATCHED microphones. The two mics are not only very different in size and capabilities, but as you said, they are positioned horribly for stereo recording. The bottom mic is the only one that does decent recording. The other is barely useable for FaceTime and such.

Exactly.
The 2nd one is mostly for noise cancelation and such smaller capabilities than the main bottom mic.

The mic configuration is so that one mic can be used for recording (depending on how the phone is pointed) and the other(s) can be used for noise cancellation, which Apple thought (and it makes sense) was a more worthwhile thing than stereo recording.


Of course, if you need to record in stereo, you can get a stereo mic for your iPhone.
