Audio Range Seek Server (ARSS) ensures that audio has a standardized format for downstream applications. It provides sample- or frame-accurate audio time ranges. Request an audio file under the media root and use query parameters to slice and re-encode it on the fly. It uses the W3C Media Fragments temporal dimension, passed as ?t=, and caches responses.
t=START,END — time range in seconds (e.g. 10,20); omit for the whole fileformat=wav|mp3|flac|opus — output encoding (default wav)channels=original|downmix — downmix averages all channels to monosamplerate=N — resample to N Hz (8000–384000); needed for Opus from non-48 kHz sources
