Codec battery usage (MP3 vs M4A vs OGG, etc)

Recommended Posts

I've been looking into this for a little while now, and can't really find a definitive answer. Maybe someone here will know:


Which of the popular music codecs, MP3, M4A, OGG, etc., are most efficient for battery use? All my music is encoded in OGG, but would it be better to use M4A (AAC) if it's lighter on the battery?


Does it make a difference in Android at all? I've read about something called OpenSL which seems to provide hardware acceleration for decoding music, but I know nothing about low level stuff.


Anyone know..?

Of course, M4A is better than MP3 because M4A is generally regarded as the successor to MP3 but compared with MP3, M4A can compress audio with the same bit rate in smaller file size.  While M4A is one of the popular audio formats developed and generalized by Apple. M4A is seldom compatible with devices except for Apple devices. If you want to play audio on devices other than Apple, then you’d better transfer M4A audio to WAV. Compared with M4A to MP3, M4A audio to WAV can keep the original audio quality.more info: http://www.videoconverterfactory.com/tips/m4a-to-wav.html As for OGG, the Ogg container format can multiplex a number of independent streams for audio, video, text, and metadata.  more info: https://en.wikipedia.org/wiki/Advanced_Audio_Coding:)
