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

* 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.
* To play DSD files, you need a DAC that supports DSD over PCM (DoP).
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.
You can also assign settings for each musical genre.
