hi there,
i would like to make a new app with corona, but for that i would
need a proper recognition how loud is someone speaking in the mic.
I use:
local r = media.newRecording()
r:startTuner()
r:startRecording()
local v = r:getTunerVolume()
and ask for v=r:getTunerVolume() in a loop
i get values around (total silence) 0.07
and each normal speech immediately jumps up to around 0.53
while really loud speaking gives 0.59 and thats it…
sometimes a 0.6 appear… but by luck…
anyhow… its impossible to recognize a normal range of volume…
i made a lot of tests from lets say 0-10 very silent to very loud speaking
from 0-2 is silent rest is immediately 9-10
is that a bug and will be fixed soon… as mentioned in that state that feature is not useful.
(i made several apps on native iPhone Xcode and there the peak times are perfect to measure volume peaks, so its not on the iphone) 
finally i just like to activate an action when someone speak really loud… but right now, even someone speaks normal it does show me “Loud”, its just not fine… don’t know better how to explain
greets
chris
