PowerAmp Music Player has for long been the standout music player on the Android OS ecosystem. With its excellent music playback, extensive audio codec support and equalisers.

The developer behind PowerAmp has just made an alpha build of the third version of app public. The new version brings a lot of changes such as a change in the Audio Engine and Visualisations, however the most noticeable is the slight change in the UI of the app with the addition of a side menu which should make navigation a tad easier. The App still maintains its retro look which is a bit disappointing. The full changelog are as follows:

- new audio engine
- Poweramp now uses 32-bit float sample representation
- Poweramp core DSP now uses 64-bit float internal math, helps a lot for accurate high amplification of basses
- Reverb with presets, improved StereoX effects
- Tempo control
- mp3, aac, ogg vorbis, opus and other lossy formats now decoded directly to 32-bit float representaion (no intermediate conversions)
- opus, tak, mka, dsf, dff formats support
- Poweramp now always properly fades in/out and ramps volume changes to avoid clicks and pops during any transitions (resume/pause/seek/etc.)
- Poweramp now applies gapless smoothing between gapless tracks
- Poweramp now always uses own resampler
- optional SoX very high quality resampler
- output Dithering options
- OpenSL optimized output
- support for 3rd party plugins (DSP/Decoder/Output)
- visualizations
- full support for milkdrop presets
- v1 and v2 (with shaders) presets supported. Support for v2 presets is best on OpenGL ES 3.0 enabled devices
- milkdrop presets can be loaded from sdcard and downloaded as APKs from Play
- support for 3rd party preset APKs
- spectrum visualizations
- main player right drawer for fast Equ/DSP/Visualizations access
- many other changes, more changes are planned
Planned features for next betas:
- improved Album Art area navigation
- new spectrum-like seekbar
- improved tablet UI

- various plugin APIs published with sample apps
- improved info/tag editing
- some cloud support
