WMA to OGG for Podcasts

Podcasters hit this specific conversion because CDs ripped in Windows Media Player during the 2000s is where the WMA came from — a remote guest, a field recording, a clip — and WMA has been abandoned — macOS, iPhones, most Android apps, car stereos and smart speakers all skip it. For a show you need OGG, so the WMA-to-OGG step is part of the edit, not an afterthought.

OGG is what you publish — Apple Podcasts, Spotify, and every RSS-based host expect it. The order matters more than the format: record and edit on a lossless file, and encode the OGG once, from the finished episode. Converting early means every later edit sits on top of lossy audio and your export adds another generation on top of that.

Podcast bitrates are lower than most people assume, deliberately. 128 kbps stereo is the widely used standard, and 64–96 kbps mono is entirely respectable for pure speech — it roughly halves the download for every listener, which adds up across a back catalogue and matters to anyone on limited mobile data. Reserve 192 kbps and above for shows where music genuinely carries the experience.

Mono is the decision most worth revisiting. If your episode is voices with no meaningful stereo image — which describes most interview and solo shows — mono at 96 kbps is perceptually equivalent to stereo at 192 and half the size. Publishing stereo by default is a habit, not a requirement. And archive the lossless edit: social clips, best-of segments, and fixes should always be cut from that, never from the published file.

You won't save meaningful space — the two formats are within touching distance at 1.2–1.2 MB per minute. Re-encoding lossy to lossy compounds artifacts. Convert once, at a high bitrate, and keep the result rather than round-tripping again.

Where does a WMA file even come from? Usually CDs ripped in Windows Media Player during the 2000s, when it was the Windows default. The catch is that WMA has been abandoned — macOS, iPhones, most Android apps, car stereos and smart speakers all skip it. OGG is the destination because it plays essentially everywhere — game assets and every ordinary phone, browser, and player. Sizes are comparable: WMA and OGG both sit near 1.2–1.2 MB per stereo minute, so this conversion is about compatibility, not storage. Both WMA and OGG are lossy, so this pair stacks a second encode — at a generous bitrate it stays inaudible, but if a lossless original of the WMA exists, encode the OGG from that instead.
