Decodes DRM (Digital Radio Mondiale) signals coming in through the external microphone input.
(We need to supply DRM signal to microphone input.)
The DRM app is for DRM30 decoding with HE-AAC. The free DRM app decodes sound and metadata only.
The DRM app requires a RC high pass filter audio line as well as a RF front-end module with antenna, tuner, modulator, IF mixer, AF amplifier.
If a call is received while the app is running, please remove the audio line connected to the external microphone jack.
If there is no input signal from Radio for more than 5 minutes, or after receiving a phone call, the DRM+ app may behave abnormally, in which case pressing the Clear button once will fix the problem.
