2, OK now in the Audacity interface we click "File"-"open" to the computer you want to process the file import.
3, click "Open" as shown below.

Audacity is a free open source program for editing audio recordings. It can run on multiple platforms (Windows/linux). Audacity is a GUI-based, powerful program with a variety of options. It allows you to record various types of sounds. Displays a screen. You can display data in multiple parallel tracks, and you can cut, copy, and paste the time portion of the source data, and you can even add special effec
First of all, this is the first time I have compiled such a large project, so I have taken some detours. Because I want to learn about speech processing, I will compile the source code of audacity under sf. I use audacity1.3.9 version. first, find the compile.txt file in win.com. This is the instruction file compiled in windows. The instructions above are clear (only in English) and the compilation tool is vs2008.

1, we open audacity on the computer.
And then we open the audacity and then we open it and we click on "No More on startup" and we click "OK" to see the effect as shown below.
2. After opening the audio file, we click "File"-"open" and then import the file to be processed.

1, click and Open Audacity. The first time you open will jump out of a hint, we need to "start no longer show" before the check, and then click "OK".
2, in the menu bar leftmost "file" select "Open", and open a we need to format conversion processing of audio files.

Multi-process scheduling is essential for the operating system. Some people say that process scheduling is the most important part of the operating system. I think this is an absolute saying, just as many people say that "a function is XX times mor

During database operation and maintenance, files are often transferred between systems to perform operations such as data extraction, conversion, and integration. In addition, statistical scheduling is performed after data integration. Here, I will describe an ETL
First, the common batch processing job scheduling algorithm1. First come first service scheduling algorithm (FCFS): is according to each job into the system's natural order to dispatch the job. The advantage of this scheduling algorithm is to achieve simple, fair. The disadvantage is that it does not take into account the comprehensive use of various resources i

Scheduling Algorithm and Resource Scheduling Algorithm
In a multi-channel program environment, there are multiple processes in the main memory, and the number of processes is usually more than the number of processors. This requires the system to dynamically allocate the processor to a process in the ready queue according to an algorithm for execution. The task of allocating the processor is completed by th
