Decibel is an audio player tailored to the particular needs of audiophiles.

Decibel supports all popular lossless and lossy audio formats including FLAC, Ogg Vorbis, Musepack, WavPack, Monkey's Audio, Speex, True Audio, Apple Lossless, AAC, MP3, MOD, DSF, DSDIFF, WAVE and AIFF.

For lossless formats such as FLAC and WAVE, and for Ogg Vorbis and specially tagged MP3 files, Decibel supports gapless playback with seamless transitions between tracks. Decibel also features replay gain adjustment for more comfortable listening.

Decibel has an intentionally minimal user interface designed to be instantly intuitive and non-intrusive. Decibel has an optional 31-band equalizer for unlimited sonic adjustment and provides precise digital and device volume control.

For users desiring more control over their audio, Decibel can take exclusive control of the output device using hog mode. Additionally, Decibel can automatically adjust the output device's sample rate to that of the playing track, preventing audio quality degradation associated with software sample rate conversion.

Finally, Decibel can load and play files entirely in memory, eliminating audio glitching associated with disk access.

For users with exaSound DACs, Decibel supports native DSD playback via ASIO. Decibel also contains DoP (DSD over PCM) support.

Decibel requires Mac OS X 10.7 (Lion) or later.
