None, for the time being, with the latest versions of USB Audio Recorder PRO as far as I know.

  Ok, time for the first public beta of USB Audio Player PRO!
 
You can download it here:
USBAudioPlayerPROTrial_0.0.4.apk
 
Notes:
 
  1. This is a BETA, meaning anything can happen. It can crash, burn, rip your ears apart etc.. or it might just work.. 
    biggrin.gif
  2. There are some (serious) limitations in this demo while we think of the best way to handle demo limits:
  * Time limit of 20 minutes
  * Max. around 8 songs (if you exceed it, it will start giving errors like 'Error playing back')
  * Some other secret limits :)
  1. If you have started UAPP without a DAC connected, it might be needed to force stop the app (or restart your device) before it gets recognized again.
  2. Some mono files are not supported (wav's are ok, mp3's are not).
 
Features compared to USB Audio Recorder PRO:
  1. Functions as 'regular' media player
  2. Play lists
  3. Gapless playback (if sample rate isn't changing between two audio files)
  4. Support for mp3 files
  5. Support for .m4a etc. files depending on your Android device
  6. Background playback (meaning that you can turn off the screen, go to other apps etc.)
  7. Sample rate conversion (if your DAC doesn't support the audio file's sample rate, it will be converted to a higher sample rate if available or the highest if not available)
 
Please contact me BY EMAIL (info AT audio-evolution.com) if you find problems. This forum is not a bug report forum for this app!

  I just tried the beta trial of UAPP and it kind of sounds weird (congested?) as opposed to the native USB audio on the Int S4 running CM11

What you get out of UARP and UAPP is the the pure unaltered sound. When you use the standard audio/CM11, you get 16-bit audio, processed by the audio chain of Android, which can include equalization and all sorts of mess/'improvements' like Dolby processing etc. There is likely going to be a difference. I'd be pleased to hear samples of both outputs, but you would need to record both streams somewhere in high quality as well.
In case you are playing mp3's, there can also be different codecs involved since we use libmpg123 to decode.

Hmm... I play FLAC files and tested with Neutron MP with all effects disabled and no audio mods installed, and also with UAPP. Maybe I'll try comparing with UARP. I could have gotten too used to the sound from neutron

Perhaps. Can you tell me which DAC you use and which sample rate your flac is that sounds different? Also, let me know if your DAC has an indication of sample rate.

OK, thanks!
 
BTW, it is not so straight-forward to find the paid version in Google Play Store: I tried searching for USB Audio Player Pro, and never got the UAPP. The only way I could find it is to go to UARP, and then select "See more from this developer" - is it just  me or this is the way it should be?

Unfortunately, that is the way the Play Store works. The term 'player' is used so often that a lot more apps hit the search target. If you search for "usb audio player pro" with quotes, you will find it directly. Searching without quotes will display it, but currently on position 108.
 
What would help is if people would rate the app (some already did, thanks!) and of course purchases help as well. :)  The rating system of the Play Store is on one hand complex, but on the other hand it's a system that drives the most income to Google: they put the best-selling and top-rated apps on top (which becomes a self-fulfilling prophecy at some point).

Bought and rated! :)))

Brilliant Christmas present! Just purchased, +1'd, shared to Twitter, 5-star rated. Deserves all the kudos it can get. Very solid 1.0 version, over time hopefully we'll see a few more things added to the music player capabilities, but for now I'm just ecstatic to have a reliable means of using USB audio with all my Android devices and not finding this or that DAC doesn't work with my latest phone.
 
Really need to dust off my video camera and get some more YouTube videos going, this deserves a feature.
