and truth, the closer it is to sound like an immersive voice, and the closer it is to the standard of HD audio. Therefore, we can say that to determine whether we have heard HD Audio, multi-channel 5.1 surround sound is the most basic. The 6.1 or even 7.1 multi-channel surround sound extended on this basis is closer to the definition of HD Audio.However, from the "audio channel" perspective, the so-called HD Audio has already been implemented. Even many years ago, the audio standards of the DVD

I have read two paper articles today. One is an important algorithm of Contour Grouping in and: Structrual Saliency [1]. The other article is specially designed for this article [2]. Alter and Bassri B are too harsh on the Ullman and sha'shua algorithms. They are all mixed at the Weizmann Research Institute in Israel. Why ~~ Haha, it's fun to read this article! Reading is quite enjoyable, because sha'shua and Ullman have not been improved. They [2] provide three criteria:

Comparison Between Media Foundation and DirectShow We have entered the era of HD Digital Media. In the future, Digital HD will be everywhere. However, he needs robust protection, which is not available on the current digital media platform. Media fundation exists for this purpose.Let's take a look at the high-definition numbers. This platform needs to be flexible and easy to recover from small failures. A large number of different quality video and audio. Media foundations must be considered for

What is AAC? AAC, Advanced audio coding, is a technique for compressing digital audio files. officially part of the MPEG-4 standard, itIsMost widely used to create small digital audio files. The current variant is specified in ISO/IEC Standard 14496-3. AACIs conceptually similar to the ubiquitous MP3 format. like MP3, it takes advantage of deficiencies in human hearing to discard Digital bits corresponding to sounds unlikely to be heard. the human hearing system cannot hear quiet sounds in th

retain customers. Study user experience design from around the world and apply this knowledge. Strive to create a product that truly conforms to the user experience design. Success Criteria: reputation and viral marketing among users User experience design VS lean Design In fact, these two design methods are not completely opposite. Their core is the same: user-centered design. The sooner you meet your needs, the better the product will be. Users don't care how you build a product or how much y

Cocos2d-x Optimization in image optimization, cocos2d-x optimization picturesIn 2D games, images are undoubtedly the most important resource files. They are loaded into the memory and converted to textures, which are rendered by the GPU on top of the genie. It can be optimized in many aspects, including: image format, puzzle and texture format. Below we will introduce the optimization of one piece and texture from these aspects.1. Select the image formatTo answer this question, we need to first

Recently I bought the most expensive headset I have ever purchased: Baiya dt131. According to official instructions, this is an entry-level hifi headset. however, when I received the goods and started to try it out, I was a little disappointed: the sound quality was similar to that of the goods sold for dozens of dollars, and the appearance was still ugly. I started to query the relevant information online. After one afternoon and one night, I finally figured it out. HIFI is short for English

maintained or transmitted. In contrast to serialization, deserialization converts a stream into an object. These two processes can be combined to easily store and transmit data. . NET Framework provides two serialization technologies: Binary serialization maintains type fidelity, which is useful for retaining the state of objects between different calls of an application. For example, objects can be shared between different applications by serializin

I will give you a detailed analysis of the Illustrator software to share with you the tutorial on creating the extremely realistic smog effect.Tutorial sharing:Step 1. Create a document and then use the rectangle tool (M) to draw a rectangle. You can set the size as needed, fill it with black, and lock it.Step 2: use the pen tool to draw a vertical line. The stroke is white, no fill, and the width is 0.05mm.Step 3: Select the stroke, move 05mm horizontally, and copy it. Then press Ctrl + D (Obje

Axure draws on the office interface to help users get started quickly. It also provides a wide range of component style changes, allowing users to create interfaces with low fidelity, high fidelity

on the issue, the method is basically similar. The idea is similar to the conventional super-resolution method based on reconstruction, it is to establish the observation model, and establish the reconstruction cost function according to the data fidelity and regularization terms. The difference is that the data fidelity is somewhat different, because it is necessary to consider the quantization noise and

Serialization is the process of converting an object's state to a format that can be persisted or transmitted. The opposite of serialization is deserialization, which converts a stream to an object. These two processes combine to make it easy to store and transfer data. Several serialization techniques: 1 binary serialization preserves type fidelity, which is useful for preserving the state of an object between different invocations of an applicatio
