The Engineered Network shows are predominantly recorded using AudioShare, post-produced using Ferrite and published using Transmit for iOS on an iPad Pro. On the 10th of July, 2017 now that the final key MP3 patent had expired on the 9th of April, 2017 Ferrite was updated to include MP3 encoding as well as chapter markers in both formats. Following this, all episodes previously post-produced using Ferrite had their original audio pulled from the archives, and re-encoded in an MP3 format.
All episodes of Analytical as well as the most recent 8 episodes of both Pragmatic and Causality have also been upgraded to high bitrate VBR MP3 format. This will improve the overall final quality as well as fix any compatibility issues between different podcast playback devices that don’t support the M4A format.
As of now, all TEN shows are in the MP3 format and will remain that way for the foreseeable future.
