Why 112 kbps joint stereo is the sweet spot
Joint stereo keeps dialogue centered and collapses redundant information. At 112 kbps you can serve hour-long episodes under 50 MB, ideal for mobile downloads.
When to switch to mono
If your show is entirely voice, exporting to mono at 80 kbps halves the file size with minimal perceived loss. Ensure your host re-encodes gracefully to avoid double compression.
