Currently, the spectrum resource is sparse, requiring a system that optimizes use this. An option for radio broadcast is the use of digital radio techniques. These techniques are available standards DAB, DRM, IBOC and have extensive advantage over analog systems, for example, flexibility and audio quality. The choice of the most appropriate digital radio technique is a very important problem, and check of multilateral performances is necessary to countries considering the release of digital radio broadcasting service. In Brazil some tests with digital radio were performed, but no further definition of what standard to use. This paper aims establish some technical comparison of the leading digital radio standards available. Another goal is to present the movements of activities with digital radio in Brazil. Performing some direct comparisons between the patterns, it was observed that DRM is interesting in order to coverage and being open source, while IBOC (HD Radio) is a hybrid system, however proprietary.
