Swiss based Merging Technologies has announced the availability of the PureNotes Denoiser for Pyramix, a new noise reduction system. The PureNotes algorithms analyze the music in short frames (from tens to a few thousand samples at a time) and for each frame identifies the noise and music components. The noise components are then removed, using an intelligent algorithm which further examines the frames to ensure that music with characteristics similar to noise is not removed.
All processing is linear phase, preserving the phase characteristics of the original signal. The signal identification and separation can be automated, done semi-automatic or manual and the process can be applied to material at all sample rates from 44.1kHz to 352.8kHz (DXD).
