摘要： A process and system for enhancing and customizing movie theatre sound includes receiving an input audio sound and enhancing the voice audio input in two or more harmonic and dynamic ranges by re-synthesizing the audio into a full range PCM wave. The enhancement includes the parallel processing the input audio via a low pass filter with dynamic offset, an envelope controlled bandpass filter, a high pass filter, adding an amount of dynamic synthesized sub bass to the audio and combining the four treated audio signals in a summing mixer with the original audio.

摘要： A method for producing an optimum sound field of loudspeakers is revealed. Firstly enclose a surface of a human head with a first closed geometric shape. Then enclose the first closed geometric shape with at least one second closed geometric shape. Next set up reference points on the first and second closed geometric shapes respectively. Use signal strength of the reference point on the second closed geometric shape and a gradient of the corresponding reference points on the first and second closed geometric shapes to obtain a transfer function of each point between a virtual loudspeaker/a real loudspeaker and the sound field respectively. Then create a virtual sound field and a real sound field according to the above transfer functions. Finally, get an optimum signal of the real loudspeaker by minimizing an error between the virtual sound field and the real sound field with a boundary condition.

摘要： There is provided a sound processing apparatus and a sound processing method which are capable of reproducing discrete data with a high-quality sound matching users' preferences. In a sound processing means 2, since an interpolation value reflecting a value of a variable parameter α by which the value of a control sampling function c0(t) is multiplied can be calculated, an analog signal obtained through the interpolation performed in a sampling function sN(t) can be regulated in accordance with the variable parameter α by changing the value of the variable parameter α. In this way, by allowing the user to appropriately change the variable parameter α in accordance with various conditions including music reproduction environments, sound sources, musical tones and so on, it becomes possible to reproduce high-quality-sound music in which its frequency characteristics of the analog signal have changed and a high quality desired by the user is obtained.
