Engineering considerations

Quality is
a set of decisions.

Perceptual quality

Choose an audio format in relation to the material and the listening conditions.

Bandwidth & compatibility

Consider network cost and device support together.

Loudness

Reference ITU-R BS.1770-5 and EBU R128 in the loudness workflow.

Operational boundaries

Separate source audio, encoding, playout and public delivery.

Standards inform the engineering approach; this page makes no certification or service-level claim.
