Problems solved by technology

[0003] Hi-Res Audio has one downside: file size
While storage is a lot cheaper than it used to be, file size issues without compression still make hi-res audio difficult to stream over Wi-Fi or mobile networks

Embodiment Construction

[0032] First, it should be understood that although the illustrative implementation of one or more embodiments is provided below, the disclosed system and / or method can be implemented using any number of techniques (whether currently known or existing) techniques. . The present invention will be limited to the exemplary implementations, figures, and techniques shown below, including exemplary design and implementation of the appended claims, but can range and equivalents in the appended claims. Modifications in all ranges.

[0033] High resolution (HI-RES) audio (also known as HD audio or HD audio) is a marketing term for recording music retailers and high-fidelity sound reproducing equipment suppliers. Due to more products, streaming services, high-resolution, high-resolution audio, will gradually become mainstream. However, different from HD video, high resolution audio has no unified general standards. Digital Entertainment Group, the US Consumer Electronics Association and t...

Abstract

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for performing residual quantization are described. One example of the methods includes performing a first residual quantization on a first target residual signal at a first bit rate to generate a first quantized residual signal. A second target residual signal is generated based at least on the first quantized residual signal and the first target residual signal. A second residual quantization is performed on the second target residual signal at a second bit rate to generate a second quantized residual signal, wherein the first bit rate is different from the second bit rate.

Description

Technical field [0001] The present application relates to a signal processing, and more particularly to improve the efficiency of the audio signal codec. Background [0002] High-resolution (HI-RES) audio (also known as high-definition audio or high definition (HD) audio) is a marketing term for recording music retailers and high fidelity sound reproducing equipment suppliers. The simplest that high-resolution audio is often referring to a sampling frequency and / or a sampling frequency and / or a bit depth (specified as 16-bit / 444.1 kHz) high-quality music file than the sampling frequency and / or bit depth of the compressed disc (CD). . The high-resolution audio file for the main requirements protection is better than the excellent sound quality of the compressed audio format. Due to more information on playback files, high-resolution audio tends to have more details and textures, making the audience closer to listen to the original performance. [0003] High resolution audi...
