Fidelify uses Spotify Core to deliver streaming content in a bit perfect stream directly to the soundcard, using either ASIO or WASAPI. In addition the player itself is optimized for minimal jitter. Convolver DSP is integrated in the player to allow real time FIR filter correction of the audio stream (room correction), and a custom VST module to allow users running an additional DSP effect or EQ on the audio stream (breaks bitperfect chain).

Fidelify is currently in beta, which means that a fully functional verified stable release is not yet ready. Please forward any bug reports to

The new 1.0 version of Fidelify has been delayed, as development is temporarely suspended. We hope to resume development within a month or two.
