## What is Kalliopeia?

Kalliopeia is a high resolution music player app.


Features:

1. High-res audio playback
 Supports up to 5.6MHz DSD and 384kHz PCM high-res audio. Capable of playing song synced to your iTunes.

 Compatible Formats
　- DSF / DIFF
　- FLAC
　- WAV / AIFF
　- ALAC(Apple Lossless)
　- AAC

* A device with a portable amp or other function that supports high resolution is required to output high-res audio at its original quality. Headphones plugged directly into a headphone jack will output at 44.1kHz or 48kHz.

2. Converts standard audio files to high-res using upsampling
 Kalliopeia links to your connected device to provide upsampling and playback at up to 192kHz.

* Kalliopeia has a fairly high CPU utilization rate, so your battery may drain faster when it is in use.


3. Built-in 11-band equalizer for bringing out that high-res power
 Built-in 32Hz~32000Hz 11-band equalizer.
 Use the 20 stock presets, or create and save your own settings.

### 2/5 — Great sound, but...

*2019-02-08*

The music sounds great, but for some reason it only plays in shuffle mode. I looked in settings and saw no options to turn this off. Did I miss something? This is quite annoying and will probably cause me to delete the app.

### 5/5 — Good sound! Gapless playback too...

*2016-01-17*

UI is simple and easy on the eye too. Highly recommended.
