  "The majority of the music you hear on KCEA is digitized from 78 RPM records. DART Pro is the software application we use in the restoration process of those records."
Michael Isaacs, General Manager

Key Features:
  • Special audio restoration and quality improvement functions:
    • Eliminate impulsive disturbances (Click and Pop removal)
    • Eliminate broadband/wideband noise (Hiss and all types of background noise removal)
    • Eliminate harmonic disturbances (Hum & Buzz removal)
    • Noise suppression based on a psychoacoustic model of the human auditory system. (Improved results)
    • Replacement and reconstruction of large and small fragments and losses. (Replacement and Drop-out reconstruction
  • MT™ (Multithreading) Support uses all CPUs simultaneously in a multi-CPU system for much faster processing.
  • Works with 16 & 24 bit and up to 96kHz wave files and sound cards.
  • Works with Music or Speech Recordings.
  • Automatic tool settings as well as manual settings audio tools for full control.
  • GUI - Graphical User Interface for sound file visualization. (Waveforms, parametrics & spectral views)
  • Filter Builder for unique combinations of tools and processing options.
  • Batch processing. (For lengthy unattended processing)
  • Full background processing. Process files in the background while using other programs.
  • Analog audio capture. (Via the Sound Card)
  • Documentation. (Online Help and Electronic Manual)

Applications - Who is using the best audio restoration system?
  • Audio Engineers - Professional re-mastering of music and post production audio quality work.
  • Project Studios - Remove and reduce audio distortions from vocal and instrumental tracks.
  • Forensics Analysis - Investigative and Evidentiary audio analysis.
  • Historians and Archivists - Recovery of historical voice recordings, or lecture tape clarification and amplification.
  • School music labs - Teach digital audio, audio science and music history.
  • DJs - Music Recovery & Audio improvement.
  • KJs - Removal of lead vocal and adding sound affects. (audio prep for Karaoke authoring)
  • Music lovers - Restore and Save the music you love from records, tapes, cassettes, and video.
  • Record collectors - Music Restoration, Preservation, & Listening.

Eight Powerful Sound Quality Improvement Functions -
  1. DART DeClick MT™ - Elimination of impulsive disturbances and low intensity wide band noise. The tool isolates and reconstructs irrevocably distorted signal samples.
  2. DART DeCrackle MT™ - An advanced tool for elimination of impulsive disturbances, based on bidirectional processing of audio signals (it combines results of forward-time and backward-time signal analysis).
  3. DART NoisePrint™ - A special noise identification function selects a fragment of a recording that contains noise only - a short piece of "silence" preceding or after a recorded signal. Or extract the NoisePrint from another recording.
  4. DART ReTouch™ - Manual control of DeClick and DeCrackle including replacement and reconstruction of large fragments useful for repairing long-lasting disturbances or dropouts.
  5. DART DeNoise MT™ - Elimination of a broadband noise of known characteristics using NoisePrint to identify a specific noise pattern.
  6. DART MaskNoise MT™ - Noise suppression tool based on a psychoacoustic model of the human auditory system. MaskNoise identifies noise components of corrupted audio files and divides them into audible and inaudible components, "masked" by the audio signal. Only the audible components are removed.
  7. DART DeHiss MT™ - A wideband noise reduction utility based on a standard noise model. Used when a noiseprint is not available.
  8. DART DeHum™ - Elimination of harmonic disturbances. (Hum and Buzz removal)

New Features -
  • Windows 7® Support - Runs on 7! (and Windows XP®)
  • MT™ (MultiThreading) Support - Uses hardware SMT and Microsoft Windows Preemptive Multitasking to achieve simultaneous processing on all cores in a multi-core system for much faster processing - as much as nX on an n CPU system! DART MT is automatically invoked when multi-CPU systems are in use.
  • Faster Processing - Many tools run faster due to software optimizations increasing single CPU performance.
  • Faster File Duplication - Up to 5 times faster file duplication.
  • Improved Buffer Management - No limitation on buffer assignments and more efficient use of buffers improving perfrmance.
  • Improved Realtime Support - Software optimization improvements made.
  • GUI Improvements - A complete set of shortcuts and mouseclicks for easier control.
  • Full Background Support - Use other programs while DART runs in the background.
