Summary
The DAB+/DAB Radcap receives and decodes the entire contents of a DAB+/DAB ensemble, rendering each audio service as a virtual Windows audio capture device for use with multi-channel recording or monitoring software. Broadcast data services, including DLS text and MOT slideshows, are also available through a simple application programming interface.
The card supports both legacy DAB MP2 audio coding as well as the new HE-AAC v2 encoding used with DAB+ broadcasts.
Multiple cards can be installed, allowing simultaneous monitoring or recording of several ensembles.
A sample application is provided with the card, allowing monitoring of DAB+/DAB audio and data as well as providing a diagnostic ensemble spectrum display, signal quality indicator and uncorrected error counter.
