Mic Tester appears to be a factory testing app for the DS microphone and speakers. As of writing this, there are two known versions of Mic Tester.
This version uses a UI similar to that of NTR Aging/Nitro EVA
. It comes with 4 major tests:
, Plays some simple sound effects and music to test the speakers
, A few microphone tests. One is the
SAMPLING DATA GRAPH
, which displays a real time graph of the mic input.
- MIC CHECKER
, Appears to be another microphone test, though it's impossible to use as it requires special factory hardware
- SPEAKER TESTER
, Plays a tone in the left and right speakers to make sure they're working
This also comes with the standard NTR Aging tests like:
- COMM TEST
- Port Checker
- ROM HEADER
, Display cartridge header info
This later version has had nearly feature stripped, with the exception of
. It does not have the NTR Aging styled menu or any of the tests mentioned above.
