# Decibel
Decibel version 2 is the next-generation high-quality audio player.
# Features
## Library Management
Decibel supports full-fledged music library management:
- View your collection grouped by album or artist or as a customizable list of tracks
- Create and manage playlists and smart playlists
- Fast searching and filtering
- Full metadata editing
- Replay gain analysis
- _Note_: Automatic file renaming and organization is not supported
The speed and flexibility of Decibel’s library is made possible by [FeistyDB](https://github.com/feistydog/FeistyDB).
## Audio Playback
Audio playback is built on an improved [SFBAudioEngine](https://github.com/sbooth/SFBAudioEngine).
### Supported Formats
Decibel supports playback of all popular audio formats including [FLAC](https://xiph.org/flac/), [Vorbis](https://xiph.org/vorbis/), [Musepack](https://www.musepack.net), [WavPack](http://www.wavpack.com), [Monkey’s Audio](https://www.monkeysaudio.com), [Speex](https://www.speex.org), [Opus](https://opus-codec.org), [True Audio](http://tta.tausoft.org/), Apple Lossless, Shorten, AAC, MP3, Module (Mod) files, DSF, DSDIFF, WAVE, and AIFF.
### Playback Features
Decibel supports gapless playback and replay gain adjustment for most audio formats.
Decibel can optionally set the output device’s sample rate to that of the playing track to prevent audio quality degradation associated with software sample rate conversion (SRC). When software SRC is unavoidable Decibel allows the computational complexity of the SRC algorithm to be adjusted.
### Direct Stream Digital (DSD)
On supported Digital-to-Analog Converters (DACs), Decibel supports DSD over PCM (DoP). For DSD64 (DSD sampled at 2.8224 MHz) Decibel supports DSD to PCM conversion.
### Multiple Device Support
Decibel allows simultaneous playback of different audio tracks to different audio devices.
## Download
The latest beta version of Decibel version 2 is [Decibel 2.0 beta 37](https://s3.amazonaws.com/feisty-dog/Decibel-2.0b37.dmg).
