Reception Quality Comparison: Analog AM in Brazil vs. Digital AM in India (DRM)

The recordings presented in this comparison were captured in a real-world environment. This means the audio may exhibit some loss compared to what would be heard live, in person. However, the comparison remains valid, as both videos were recorded under the same ambient conditions. Therefore, any potential losses affect both cases equally, allowing for a fair analysis. The difference in clarity can thus be perceived subjectively by the viewer.

Digital Environment in DRM – AM 1368 (Video 1)

Analog Reception – AM 1280 (Videos 2 and 3)

• Reception: João Pessoa/PB

• Transmitter: Bayeux/PB (metropolitan region of João Pessoa)

• Distance between transmitter and receiver: 12 kilometers

• Recording time: 4:15 PM

• Environment: Urban area

Analog Reception – AM 1170 (Video 3)

• Reception: João Pessoa/PB

• Transmitter: Mossoró/RN

• Distance between transmitter and receiver: 310 kilometers

• Recording time: 4:45 PM

• Environment: Rural area of Mamanguape/PB

Evaluate the Differences

I have chosen not to share my conclusions upfront, as my goal is to encourage an individual perception exercise. Each listener can evaluate for themselves whether there are differences in signal stability — that is, if the audio fluctuates — and whether there is a sense of higher sound definition, such as a broader frequency response. These are questions that depend on each person’s auditory sensitivity, even if they are directly influenced by objective technical characteristics. These videos can serve as a basis for that personal analysis.
