Kalliopeia vs FolderPlay

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 　- MP3 * 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.

FolderPlay turns a folder in Files into a continuous audio queue. Choose a folder once. FolderPlay finds supported audio files, keeps their natural filename order, and starts playing without importing or copying them into another library. Come back later and continue from the same folder, file, and position. It is a focused player for lessons, recordings, mixes, demos, chapters, and music already organized on your device or in a Files provider. FREE • Play one folder from beginning to end • Keep the source folder unchanged • Background audio and lock screen controls LIFETIME UNLOCK • Save and resume unlimited folders • Bookmarks, playback speeds, and sleep timer • One purchase, no subscription FolderPlay does not upload your audio, create an account, stream a catalog, or build a duplicate media library.
