Resampling
Resampling converts audio from one sample rate to another — 48 kHz video audio to 16 kHz for a speech model, or 44.1 kHz masters to 48 kHz for video delivery.
Quality resampling is a solved problem with proper filtering, and speech pipelines resample constantly since models expect fixed rates. Artifacts appear only with naive implementations that skip the anti-alias filter.
