FxSound enhances Internet-oriented audio listening experiences by correcting for the sonic limitations of nearly all the popular data compressed Internet audio formats. Data compressed audio suffers from two major problems: loss of high frequency fidelity and loss of stereo separation and depth.
FxSound compensates for the loss of high frequency fidelity by carefully regenerating the missing high frequency harmonics in the audio. FxSound then compensates for the reduced stereo imaging and depth by carefully generating ambience and stereo depth.
An additional factor limiting the quality of Internet audio playback is the use of speakers that are narrowly spaced and located close to the listener's ears. These location constraints reduce the perceived stereo field and reduce the natural room ambience which is important to good sounding audio.
In addition to compensating for reduced stereo depth in the audio source, FxSound's added ambience and imaging works particularly well in correcting for these limitations of closely spaced and located speakers.
Typical PC-based multimedia playback systems and even home stereo playback systems also suffer from limited dynamic range and headroom. FxSound compensates for this limited headroom by carefully processing the audio to increase the perceived loudness of the audio without altering the perceived dynamic range. This can dramatically increase the undistorted playback level available when listening to MP3 and other streaming audio files.
FxSound performs all audio processing with 32-bit floating point precision, yielding truly professional audio quality. Since Internet audio playback systems currently only support 16-bit audio playback, as a final processing step FxSound carefully re-dithers the audio signal to the final 16-bit resolution using FxSound's proprietary high quality dithering technology. Re-dithering allows a dynamic range in the playback signal that actually exceeds the theoretical limit of a 16-bit playback system.
