  1. 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..?


  2. I been playing all my music by randomly shuffling albums, using the library view. This all works fine, except for when Poweramp comes to albums with the same name. In this case, all the songs are grouped together into one big playlist, which is rather strange. Instead of getting just all the songs from one album, I get all the tracks from each album played one after the other.


    In this case, I have albums by Feeder and Basement Jaxx called "The Singles", as well as some singles bought from Amazon from greatest hits albums also called "The Singles".


    The results is that Poweramp will play track 1 from Feeder, then track 1 from Basement Jaxx. Then track 2 from Feeder, and then track 2 from Basement Jaxx, and so on, eventually throwing in the random singles when their track number matches.


    Has anyone else encountered this? Is there a way around it?


    Is this what the album artist tag is suppose to solve..?


    Could changing the list view settings in the Album library view fix things? Right now, I've got it set to "By Name". If I use "By Artist" will that cure the issue, or will that have no impact..?

  3. There seems to be a lot of questions about this, but I've not seen an answer yet.


    Does anyone know how to get gapless playback to work with MP4s when using Poweramp?


    I ripped a few CDs using Nero AAC, which played back fine in Poweramp. However, the playback wasn't gapless. There is a small break of a few milliseconds between songs, which, when listening to an album where one track seamlessly transitions to another, is quite disruptive to listen to (at first I thought that Poweramp was hiccuping on the tracks).


    Are there any tags I can add to the files?


    The reason I'm interested is that right now I have most of my music in OGG. However, I've notice that the battery takes quite a beating from playing these, compared to MP4 (because the CPU usage is much higher). It's not dreadful of course, but could be better. An example:


    2 hours of playing back MP4 audio shows a total CPU usage of 13m in Android.

    1.5 hours of playing back OGG audio shows a total CPU usage of 20m (some quick maths suggests this would be almost double that of MP4).


    The OGGs are encoded at q6 (~192kps), whereas the MP4 are ripped at 0.5 (~160kps). I'm not sure that the extra 32kps accounts for double the CPU usage, but maybe I'm wrong ;)


    Tags? Ripping suggestions..?

  4. I'd like to see an extra option added to the list of Auto-advance crossfade settings. Right now, we have:


    * No Fading

    * Crossfade non-gapless / non-cue songs

    * Crossfade all songs


    Could we have an option to crossfade when shuffles songs (though not lists). So:


    * Crossfade when shuffling songs


    Rockbox had such a feature, so it would be nice to add it to Poweramp.


    A use case would be that, in the folder view, a user long presses on a folder and selects Shuffle. If the "Crossfade when shuffling songs" option is selected, the songs in that folder will be crossfaded. However, if the songs are being played as normal (using the Play option), the songs are played as normal.
