Bitrate is the primary size lever
For constant-duration audio, lower bitrate generally means fewer bytes. The right value depends on content and codec.
Mono can help spoken content
Interviews, lectures and voice notes may not need stereo. Music and spatial content often do.
Sample rate is not a quality slider
Reducing sample rate can save processing/data in some workflows, but arbitrarily increasing it never restores detail.
Use your ears and measured bytes
A professional compression decision considers both actual file savings and audible artifacts.
