Abstract

Generally disclosed herein is a system and method for correcting an audio spatial image within a vehicle. The gain and the delay of sound sources, such as speakers within a vehicle, are adjusted such that the sound sources arrive at a listener simultaneously and with the same amplitude. Symmetric output channel pairs may be identified from the sound sources, and power spectrum differences between the symmetric output channel pairs may be computed. A power spectrum equalization transfer function may be obtained and applied to each output channel pair. A center image of the sound sources may be detected, and the center image of the sound sources may be adjusted by applying additional amplitude or phase panning such that the center image may be placed in a desired position.

Abstract

Generally disclosed herein is a mechanism to increase the perceived sound field width and depth in an automotive environment without causing excessive or unnatural reverberation. The audio ambiance may be added using a cross-analysis of a vehicle cabin and a typical room's sound decay characteristics. The late reverb insertion and extraction time may be determined from the target room response and the vehicle cabin response, and the late reverberation transfer function may be computed. Once the late reverberation transfer function is obtained, the combined cabin transfer function can be measured, and a scale factor for energy equalization derived. The total energy of the sound within the vehicle cabin may be normalized and the reverberation frequency spectrum may be equalized such that the late reverberation within the vehicle cabin is synthesized with the desired energy decay of the late reverberation of the sound in a room.

Abstract

A method for processing a digital audio broadcast signal in a radio receiver, includes: receiving a hybrid broadcast signal; demodulating the hybrid broadcast signal to produce an analog audio stream and a digital audio stream; and using a normalized cross-correlation of envelopes of the analog audio stream and the digital audio stream to measure a time offset between the analog audio stream and the digital audio stream. The time offset can be used to align the analog audio stream and the digital audio stream for subsequent blending of an output of the radio receiver from the analog audio stream to the digital audio stream or from the digital audio stream to the analog audio stream.

In an improved service mode, encoded bits can be distributed between an in-band encoded component and a cross-band encoded component, where the encoded bits in the in-band encoded component are desynchronized by a specified duration with respect to the encoded bits in the cross-band encoded component. The encoded bits in the in-band encoded component can be allocated into frequency partitions that are used by a legacy service mode, such as MP1 or MP3, which can provide backward compatibility with the legacy service mode. The encoded bits in the cross-band encoded component can be allocated into frequency partitions that are not used by the legacy service mode, and are found in the opposite sideband, compared with the legacy service mode, which can provide time diversity within a single sideband.

Abstract

A method for processing a digital audio broadcast signal in a radio receiver, includes: receiving a hybrid broadcast signal; demodulating the hybrid broadcast signal to produce an analog audio stream and a digital audio stream; and using a normalized cross-correlation of envelopes of the analog audio stream and the digital audio stream to measure a time offset between the analog audio stream and the digital audio stream. The time offset can be used to align the analog audio stream and the digital audio stream for subsequent blending of an output of the radio receiver from the analog audio stream to the digital audio stream or from the digital audio stream to the analog audio stream.

A method and apparatus are provided for blending analog and digital portions of a composite digital radio broadcast signal by processing compressed audio packets to compute corresponding digital audio quality indicator values, storing the compressed audio packets in an audio blend buffer, processing audio information from each compressed audio packet stored in the audio blend buffer with an audio decoder to generate decompressed digital audio signal samples, and using the digital audio quality indicator values to guide a blending process for combining analog audio signal samples with the digital audio signal samples to produce an audio output by preventing unnecessary blending back and forth between analog and digital if the digital audio quality indicator values indicate that the compressed audio packets are degraded or impaired.
