451 MHz

451 MHz has been publishing since 2019, and across the 7 years since has built a catalogue of 226 episodes, alongside 4 trailers or bonus episodes. That works out to roughly 210 hours of audio in total. Releases follow a fortnightly cadence.

Episodes typically run thirty-five to sixty minutes — most land between 49 min and 1h 3m — and the run-time is fairly consistent across the catalogue. None of the episodes are flagged explicit by the publisher. It is catalogued as a PT-BR-language Arts show.

The show is actively publishing — the most recent episode landed 3 days ago, with 34 episodes already out so far this year. The busiest year was 2025, with 53 episodes published. Published by Quatro cinco um.
