The .Audio 476 also offers a comfortable lightweight fit, convenient inline controls, and plug-and-play USB setup. DSP Technology Offers Clear Calls and Natural Sound Experience exceptional call quality when you use the .Audio 476 to make VoIP (voice internet protocol) calls using Skype or other Internet phone services. Whether you're on the phone with friends or clients, they'll appreciate how clear you sound, thanks to DSP (digital signal processing) technology. This multifaceted technology improves both outgoing and incoming audio for crisp, natural conversation. DSP technology captures the full voice range and stabilizes the spoken voice by amplifying or minimizing certain frequency ranges. This ensures a more natural-sounding conversation and reduces listening fatigue for the person on the other end of your call. Wideband Echo Cancellation and Noise-Cancelling Microphone Sound professional no matter where you're calling from. The .Audio 476 uses a two-step approach to remove distracting background noise and improve voice clarity. First, a noise-cancelling microphone minimizes the distractions typically found in a busy home, office, or travel stop. Second, DSP enhances the performance of the noise-canceling microphone by blocking out low-frequency noise for clearer conversations. A central part of this improved sound is DSP's wideband acoustic echo cancellation, which diminishes feedback and reduces speaker-to-microphone echo (a common problem that can affect VoIP calls). Rich Stereo Sound with Noise Reduction to Prevent Distortion When listening to your favorite band or catching up on games and movies, enjoy an enhanced listening experience that includes rich, 24-bit hi-fi stereo sound provided by the .Audio 476's acoustically tuned digital equalizers. DSP technology also works to prevent the creation of artificial noise or distortion, allowing the .Audio 476 to offer smooth volume transitions that preserve high audio quality.
