There are two ecosystems for radio. The first uses an FM transmitter as its primary source, with analog audio subject to sound degradation as the listener moves farther away from the signal source. The second uses audio coming directly from the digital output of the station’s audio processor, which is not sent to a specific transmitter, but instead to an IP redundancy and distribution environment. This transmission can range from 48 kbps AAC+ to more than 256 kbps AAC+, alrea

Existem dois ecossistemas para o rádio. O primeiro tem como fonte primária um transmissor FM, com áudio analógico sujeito à degradação sonora conforme ocorre o afastamento da fonte do sinal.

Esse envio pode variar desde 48 kbps em AAC+ até mais de 256 kbps AAC+, já entregando, mesmo em ta

Over a total travel time of 1h28min, 1h26min had high‑quality audio with no static and less than 2 minutes of accumulated silence due to signal loss. The digital signal was configured at 64 kbps (AAC+) and 48 Hz, corresponding to the broadcast of Jovem Pan Natal radio station. Monitoring was carried out along different highway segments, with the aim of evaluating audio stability while in motion. On the stretch between Tangará and Serra Caiada, covering 15.6 km, audio dropou
