13.6.4. Audio format and bitrate

Your target uses a hard disk which consumes a large amount of power while spinning –

up to several hundred mA. The less often the hard disk needs to spin up for buﬀering

and the shorter the buﬀering duration is, the lower is the power consumption. Therefore

the bitrate of the audio ﬁles does have an impact on the battery runtime as well. Lower

bitrate audio ﬁles will result in longer battery runtime.

Please do not re-encode any existing audio ﬁles from one lossy format to another based

upon the above mentioned. This will reduce the audio quality. If you have the choice,

select the best suiting codec when encoding the original source material.
