    摘要: A surround experience for headphones can be created using various techniques and tools. The described techniques and tools can be applied separately or in combination. For example, a surround experience can be created by splitting input audio channel signals into high-pass and low-pass signals. The low-pass signals can undergo cross-mixing and artificial reverberation. The artificial reverberation can apply different delay profiles to the low-pass audio signals. The high-pass and low-pass audio signals can be combined to generate output audio channel signals. A surround experience can be crated using a system comprising an input module, a crossover module, a channel cross-mixing module, a reverberation module, and an adder module.

    摘要: Described techniques and tools include techniques and tools for mapping digital media data (e.g., audio, video, still images, and/or text, among others) in a given format to a transport or file container format useful for encoding the data on optical disks such as digital video disks (DVDs). A digital media universal elementary stream can be used to map digital media streams (e.g., an audio stream, video stream or an image) into any arbitrary transport or file container, including optical disk formats, and other transports, such as broadcast streams, wireless transmissions, etc. The information to decode any given frame of the digital media in the stream can be carried in each coded frame. A digital media universal elementary stream includes stream components called chunks. An implementation of a digital media universal elementary stream arranges data for a media stream in frames, the frames having one or more chunks.

    摘要: The level of an audio signal can be compressed by receiving an input audio signal, determining a measure of loudness of the signal using a perceptually derived filter, determining a target gain amount, determining a current gain amount using piecewise linear attack/release logic, and producing an output audio signal by adjusting the input audio signal by the current gain amount. An audio compression filter for compressing the level of audio can comprise a loudness measuring module configured to determine a measure of loudness using a perceptually derived filter, and a compression module configured to determine a target gain amount, determine a current gain amount using piecewise linear attack/release logic, and adjust an input audio signal by the current gain amount. Audio level compression can be implemented using integer calculations.

    摘要: Bass frequencies of audio can be dynamically boosted using various techniques and tools. The described techniques and tools can be applied separately or in combination. Bass frequencies of audio can be boosted using a linear combination of an input audio signal and output of a high-pass filter. For example, bass frequencies of audio can be boosted by applying a high-pass filter to an input audio signal to produce an output of the high-pass filter, determining a current level, determining a target gain amount, dynamically adjusting the input audio signal and the output of the high-pass filter, and combining the gain-adjusted signals to produce an output signal. A dynamic bass boost filter can comprise a high-pass filter and a dynamic boost module.
