PureBit: Hi-Res Music Player

The audiophile player with nothing hidden: bit-perfect output, a visible signal path, 10-band EQ & AutoEq. Now with library sorting. Buy once, keep forever.

Most music players show you a waveform and a volume knob. PureBit shows you the rest of it — every decoder, every conversion, every filter — so you know exactly what's happening between the file and your ears.

For the listener who cares whether a 24-bit FLAC actually plays as 24-bit. Whether the DAC is getting the native sample rate. What an EQ band sounds like when it's measured, not just imagined.

What you get:

• Lossless and Hi-Res playback. FLAC, ALAC, AIFF, WAV, DSD. Native CoreAudio path that respects your DAC's preferred format. No forced upsampling unless you ask for it.
• A live Signal Path view. Source rate, decoder output, every DSP node, the format reaching the hardware. Tap a node, see what it's doing. Tap again, change it.
• 10-band parametric EQ with adjustable Q. AutoEq integration pulls a target curve for your headphones straight from the AutoEq community (jaakkopasanen/AutoEq) — two taps and you're done.
• Audio Lab: upsampling, convolution for impulse responses (room correction, HRTF, custom), crossfeed for headphone soundstage, balance and mono tools for diagnostic listening.
• Files from the Files app, or stream from Dropbox and OneDrive. Browse and play your music by folder. Offline downloads come with Pro.

PureBit Pro

• One purchase. No subscription, no ads, no upsell. Unlocks the full Audio Lab, AutoEq search, offline cloud downloads, and unlimited EQ presets. App Store handles the payment; we never see your card.

Privacy

• PureBit doesn't track what you listen to. No analytics on your library, no listening profile sent anywhere. You bought the app — that's the end of the transaction.

Network Sources (Pro): stream your own library straight from your home network — a NAS over SMB (Synology, QNAP, Windows/macOS shares), UPnP/DLNA media servers, or WebDAV. Auto-discover servers, browse and import, read embedded metadata and cover art, and download tracks for offline listening. Bytes pass through unmodified, so it stays bit-perfect — no third-party cloud in between.
