Hello, I am concerning about ogg and flac on MP3 Player.

I know that flac is lossless and encodes use no float point library.

I know that ogg is loss and have a good test on low bitrate.

But, I wanna know ogg Q10 (or other high bitrate, such as Q9, Q8) VS. flac, which is more energy consuming in decoding ?

Since I play music on SAMSUNG YP-Q3, endurance is important.

Thanks, guys !

Probably ogg, since its algorithmically much more complex. But decoder quality varies massively from device to device, so its hard to say.

If you already have the player, load up a playlist and test how long it last with each format.

Maybe it should also be taken into account the increase in energy consumption for FLAC due to reading about three times more data from mass storage.
