OGG to FLAC for Podcasts

Podcasters hit this specific conversion because game assets is where the OGG came from — a remote guest, a field recording, a clip — and OGG plays in browsers and game engines but is refused by iPhones, most car stereos, and plenty of upload forms. For a show you need FLAC, so the OGG-to-FLAC step is part of the edit, not an afterthought.

Edit in FLAC, publish in something lossy. Keeping the working file lossless means your cuts, levelling, noise reduction, and EQ all happen on raw samples — and only the final episode export is lossy, applied once to the finished mix.

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.

The file gets bigger — roughly 4× — because FLAC stores about 5 MB per minute against OGG's 1.2. For a working file that's irrelevant. OGG is lossy, and the detail its encoder discarded is gone permanently — converting to FLAC cannot restore it. What you gain is that nothing you do afterwards costs any further quality.

Most people meet OGG through game assets. It is a fine format there; the trouble is that OGG plays in browsers and game engines but is refused by iPhones, most car stereos, and plenty of upload forms. FLAC is the destination when you need uncompressed, edit-ready audio that every DAW and editor accepts. Budget for roughly 5 MB per minute — about 4× what the OGG took. You're trading disk for a format that tools actually accept. One honest note on this exact pair: OGG is already lossy, so moving to FLAC cannot restore detail the OGG encoder discarded — it hands you an uncompressed container, not better audio, and the value is a loss-free chain from here on.
