Sound Image Localization Using Frequency-Selective Clipping Suppression

The patent applies preliminary action by detecting peaks in the head-related transfer function before sound image localization processing and preemptively applying gain reduction to those specific frequency ranges. This prevents clipping distortion from occurring during the convolution process while preserving the localization accuracy benefits of the original HRTF peaks.

The patent implements local quality by applying gain reduction selectively only to frequency ranges where peaks are detected in the head-related transfer function, rather than uniformly reducing gain across all frequencies. This localized approach maintains sound volume in non-peak frequencies while preventing clipping only where necessary.

The patent applies local quality by implementing frequency-selective gain reduction that targets only the specific frequency ranges where peaks are detected in the head-related transfer function. This allows the majority of the frequency spectrum to maintain full gain and sound volume, while clipping is prevented only in the problematic peak regions.

The patent uses preliminary action by identifying and marking peak frequency ranges in the HRTF before performing sound image localization processing. Gain reduction is then applied only to these pre-identified peak ranges, preventing clipping while preserving overall signal volume.

The patent implements local quality by applying gain reduction selectively only to frequency ranges where peaks are detected in the head-related transfer function, rather than applying nonlinear compression across the entire signal. This linear, frequency-selective approach preserves the natural frequency characteristics and temporal structure of the sound signal while preventing clipping only where needed.

The patent substitutes the mechanical nonlinear compression system (limiter/compressor) with a linear frequency-selective gain reduction system. By replacing the nonlinear time-domain processing with linear frequency-domain processing, the natural frequency characteristics and temporal structure of the sound signal are preserved while achieving clipping prevention.

The patent applies preliminary action by detecting and marking peak frequency ranges in the head-related transfer function before sound image localization processing. The gain reduction is then applied only to these pre-identified peak ranges, preserving the dip components and other important localization features while preventing clipping in the peak regions.

The patent implements local quality by applying gain reduction selectively only to frequency ranges where peaks are detected, rather than uniformly reducing all frequency components. This preserves the dip components and other important localization features in the HRTF while preventing clipping only in the problematic peak regions.
