[−][src]Function bs1770::reduce_stereo
pub fn reduce_stereo(

right: Windows100ms<&[Power]>
) -> Windows100ms<Vec<Power>>
Combine power for multiple channels by taking a weighted sum.
Note that BS.1770-4 defines power for a multi-channel signal as a weighted
sum over channels which is not normalized. This means that a stereo signal
is inherently louder than a mono signal. For a mono signal played back on
stereo speakers, you should therefore still apply reduce_stereo
, passing
in the same signal for both channels.
