[media id=143]

You probably wonder what is the quality of the audio signal of DRM – Digital Radio Mondiale broadcast transmission. Well, I did analyze a short jingle of BBC & DW DRM radio recorded via line in/line out from a PC to another. Take a short peak on the graphics below and listen the audio sequence above. Clearly that’s a high quality transmission in short wave and let’s not forget that we got Stereo sound also and may other TEXT features.
