audio - Turning off AGC on the iPad -



audio - Turning off AGC on the iPad -

there little consensus on whether ios interface apple provides shut off automatic gain command implemented. know definitively if possible shut off agc when recording sound on ipad and, if reply yes, how?

if using ios< 5...the reply no.

if using ios>=5 on ipad2...the reply still no. not

if using ios>=5 on iphone 3gs, ipod(4th gen), ipad1 (1st gen) reply seems yes.

acg turned off when audiosessionmode changed kaudiosessionmode_measurement. check sound session services reference.

input gain can controlled by:

1) set audiosession's mode kaudiosessionmode_measurement.

2) sure device using has input gain available using kaudiosessionproperty_inputgainavailable property.

3) set property kaudiosessionproperty_inputgainscalar desired gain level (between 0 , 1.0)

*haven't gotten hands on newest ipad yet, cant confirm.
