RSPlayer

RSPlayer is a music player built for high-quality playback of local
music libraries. It decodes FLAC, WAV, ALAC, DSD (DSF/DFF), MP3, AAC,
Ogg and more, and can send audio bit-perfect to a USB DAC via direct
ALSA access, or through PipeWire/PulseAudio for everyday listening.

Features:

- Fast library scanning with rich metadata, album art and lyrics
- Gapless playback, ReplayGain/loudness analysis and a parametric DSP chain
- Bit-perfect exclusive output to USB DACs, including DSD
- Internet radio and streaming metadata
- Multiroom: group RSPlayer instances on your LAN for synchronized playback
- Media key / MPRIS integration

The desktop app embeds the same engine that powers the headless RSPlayer
server, which you can also run on a Raspberry Pi, NAS or home server and
control from any browser.

For bit-perfect direct ALSA output to a USB DAC, connect the alsa
interface:

 sudo snap connect rsplayer:alsa

For music libraries on external/removable drives (/media, /mnt):

 sudo snap connect rsplayer:removable-media

Note: mounting network shares from inside the app and system power
actions are not available in the snap sandbox.
