analog-to-digital converter (ADC), which is stored in the computer. When replayed, these digital signals are sent to the analog converter (DAC), which is reduced to analogue waveform at the same sampling speed, amplified and delivered to the speaker, which is known as pulse coded modulation (PCM) technology. Main role (1) It can record a digital sound file. Through the sound card and the corresponding driver's control, collects the signal from the microphone, the recorder and so on the sound

achieve better hardness performance than traditional chemical-enhanced glass by purifying its elements and applying it to some transparent glass panels. According to what we have learned, the hardness of Sapphire is 9, and the hardness of glass is 5, and the fracture toughness of the former is 2.3mpa√m, almost 3 to 4 times times that of ordinary glass. In addition to the extremely high hardness, Sapphire also has excellent electrical and dielectric properties, and has chemical corr

Instruments has recently been used to analyze the performance of the entire application. Discover a lot of interesting points, as well as performance optimizations and some techniques for analyzing performance consumption, summarized below.Instruments Tips for useAbout Instruments official has a very useful user to use guide, of course if not accustomed to the official English can be found here in the text

Hard Canton: "iOS Performance Tuning Series" The third, continuously updated, welcome attention.iOS Performance Tuning series: Analyze static analysis describes how to find iOS memory leaks using the static analysis method, iOS Performance Tuning series: Dynamic analysis of memory leaks using instruments Explains the dynamic analysis of memory leaks using the instruments leaks tool.These two articles are al

high, the system terminates the background thread to relieve memory pressure. If enough memory is available, the app will be able to continue running without generating a crash report.Otherwise, the app will be terminated by iOS and generate a low memory crash report. There is no stack backtracking on the application thread on the low memory crash log. Instead, it shows the amount of memory used per process in memory pages. (When writing this article, the size of a memory page is 4KB.) You will

. 2. Midi, short for Musical Instrument Digital Interface, is also known as the digital interface of musical instruments. It is a unified international standard for digital music/electronic synthesis instruments. It defines how computer music programs, digital synthesizer, and other electronic devices exchange Music signals, it specifies the protocol for data transmission between cables and hardware and e

1) The memory problem is that the earlier the discovery, the lower the cost of solution. So the most important thing is to understand objective. C Memory Management follows the practices and coding specifications I mentioned earlier. In addition, some stress and memory tests are required in each iteration cycle to detect problems as soon as possible. 2) use clang static detection tools. Clang has been integrated in Versions later than xcode 3.2. Build-> build analyze can be run. It can det

. Because the preparation is different, the test limits are different. The user's end cable is always used no matter whether there is a transfer point. 5. Basic Link Basic connection) Model Definition This model describes the testing requirements for contractors responsible for installation of fixed cables only in buildings. The easy-to-remember feature of the Basic Link model is that there is only one connection point at each end of the connection, not the connection point to the tester ). Comp

IOS app memory analysis routines and iosapp memory routinesIOS app Memory analysis routines: 2 ways to view app Memory usage in Xcode: 1. Debug Memory in navigator This method is the easiest and most effective way to view Memory. When debugging a real machine, you can view the app Memory through Memory in Debug navigator. Total memory is the sum of the stack memory and virtual memory (the memory occupied by OpenGL is included in the virtual memory.Ii. Instru
