As I teach various workshops relating to educational podcasting, I frequently field questions relating to bandwidth. Today I discovered this excellent comparative table of podcast lengths and encoding bit-rates which shows the approximate sizes of podcasts of different lengths recorded with different quality levels from Liberated Syndication.
For my own podcasts that are primarly spoken voice episodes but do include some music for the intro, transitions and outro, I always encode at a bitrate of 32 kbps. This table of podcast sizes matches with my own experiences, where a 20 minute 32 kbps podcast takes up about 4.5 MB and a 60 minute podcast is 12-14 MB. When you want to calculate total bandwidth demands for a given podcast, multiply the podcast size times the number of anticipated subscribers / downloads.
Tim Wilson told me about Liberated Syndication this past week at the TCEA conference in Austin. It is the hosting solution he uses for podcasts. Their hosting features include “unmetered bandwidth,” which is a really big deal for popular podcasts. Individual as well as organizational podcasting plans are available, the individual plans start at $5 per month which includes 100 MB of uploaded podcasts per month. If you’re encoding at 32 kbps, that amounts to quite a bit of uploaded podcast content each month!
I haven’t tried Liberated Syndication myself, but I’ve added it to my “Intermediate/Advanced Topics in Podcasting” workshop curriculum.
