DSP-Quattro is an extremely powerful sound editor for the Mac OS. It's a highly innovative product that utilizes the latest technological advances of computer-based sound editing. DSP-Quattro, with it's foundation being the well-seasoned D-SoundPRO, benefits from 10 years of development and professional use in the audio production community. As the newest evolution, DSP-Quattro injects new life into sound editing by expanding the possibilities of simple sound editing into a full-fledged, professional audio workstation, effortlessly accommodating music production, plug-in hosting and advanced audio editing. You can even create final mastered files in DSP-Quattro, ready for pressing CDs.

Tremendous possibilities are offered by DSP-Quattro's built-in digital effects like reverbs, modulated digital delays, analog filter simulators and parametric or graphic Eqs. In addition, DSP-Quattro includes many more sophisticated algorithms, such as real-time hard-drive based polyphonic sample playback and real-time time-stretching and pitch shifting. DSP-Quattro expands it's capabilities exponentially as a host for third parties instrument and effect plug-ins, such as VST and AudioUnits.

DSP-Quattro is designed for the most discriminating professional users. However, because of it's simple and intuitive interface, DSP-Quattro is also an ideal product for novices in the field seeking to discover the world of digital audio. DSP-Quattro allows for professional results, it is simple to use, and with plug-in hosting capabilities, offers seemingly endless possibilities.
