Bit-perfect Android player for audiophiles with USB DACs
Sends bit-perfect audio to external USB DACs and shows a live Signal Path display that reports exact sample rate and bit depth in use. PureBit, by Dinh Van Hoang, targets high-resolution listeners and collectors. It combines file support for FLAC, ALAC and WAV, network and cloud playback, and an Audio Lab set of DSP tools for headphone tuning, making it suitable for careful listening sessions with high-end gear.
What PureBit does for critical listening
PureBit routes audio directly to supported USB DACs, bypassing the Android mixer to keep a bit-perfect path from file to device. The app surfaces the active decoder, DSP stages, and output sample rate in a live Signal Path readout, which lets you confirm that files play at their native sample rate and bit depth without unwanted resampling.
What formats and sources it handles
High-resolution lossless files play natively, with explicit support for FLAC, ALAC and WAV at up to 192 kHz/24-bit. You can open files stored on the device or stream from a home server using UPnP/DLNA, SMB and WebDAV, and access Dropbox or OneDrive for cloud-hosted libraries, so library location is flexible.
How its processing and monitoring behave
Audio Lab delivers direct control over tone and correction: a 10-band parametric EQ, AutoEQ headphone profiles, Crossfeed, Upsampling and Convolution are available for shaping output. The Signal Path transparency display updates in real time, which lets you verify whether any DSP stage or sample-rate conversion is active during playback.
Who gets the most from this workflow
The app is aimed at listeners using external DACs and high-resolution files, not casual mobile listeners. Its feature set emphasizes technical verification and precise DSP options, which suits collectors and Hi-Fi enthusiasts who pair Android devices with dedicated DAC hardware and calibrated headphone profiles.
A focused gateway for DAC-equipped listeners
If you have a USB Audio Class DAC and a library of high-resolution files, PureBit gives you a verifiable, bit-perfect playback chain and detailed DSP controls. Casual users without external gear will find less immediate value, but for its intended audience the app provides direct control and transparency that help ensure accurate reproduction.
