voice memos hiss at beginning of sharp sounds
Can anyone please confirm this is normal and not a fault with my new SE? If I record a voice memo with clicking sounds like you get if you click your tongue I get a short clear hissing which dies away quickly. This ruins any recordings with transients from quiet to loud like nature noises. I could take my phone to the shop since it is new but I suspect this is just an artefact of the level control. To test please record clicking sounds with phone mic and then plug in phones to hear the hiss. If I use an attached mic like the headset I do not get this annoying problem.
Many thanks in advance.
