Subscriber audio uploads to Apple Podcasts Connect are rejected or degraded when container, sample rate or channel layout is wrong. Conditions. Subscriber audio uploaded in Apple Podcasts Connect, not RSS-hosted audio. Method. Use WAV, FLAC or MP3.

Use the stereo source if one exists; if only mono exists, send two identical L/R channels because single-channel WAV/FLAC is not accepted. MP3 accepts mono or stereo: minimum 44.1 kHz at 32 kbps mono or 64 kbps stereo; recommended 44.1/48 kHz at 96-128 kbps mono or 128-256 kbps stereo. Failure modes. Mono WAV/FLAC is not accepted; the MP3 minimum is a floor, not the recommendation. Limitations. The page does not say what happens above the recommended range; loudness is covered by a prior finding.
