Description

MultiRecord has a sig_name attribute (which is copied from the first segment.) Should it also have units and samps_per_frame attributes, for convenience?

(An application calls rdheader in order to obtain record metadata, without reading any signal data. If the same attributes are available both for Record and MultiRecord then applications don't need to handle the two cases differently.)

Research direction

Start by locating the MultiRecord and Record definitions and the metadata path used by rdheader. Compare how sig_name is exposed for both types, then check the relevant tests or metadata-loading entry points. Done means MultiRecord provides units and samps_per_frame consistently with Record without requiring signal data to be read.
