wav cutter

WAV uses a digital signal, it is to use a bunch of numbers to describe the original analog signal, so it to the original analog signal analysis, we know that all the sound has its waveform, digital signal is in the original analog signal waveform on every time at once "take the point", give each point to a value, This is "sampling", and then all the "dots" can be used to describe the analog signal, it is clear that the more points in a given time, th

If you want to know the relationship between the MP3 frequency, bit rate, bit rate, and sound quality, the higher the frequency, the higher the bit rate, the better the sound quality. It seems that most of the MP3 frequencies are 44100hz. The bit rate is 128,192. The frequency mentioned here is the sampling rate, which is usually 44100khz, because it is the standard of music CD.Every song is captured from Cd, converted into wav files, and then convert

1. The first line is the format of the music, which is .wav. If your favorite music is not the type of the music, you must first convert it. Fortunately, there are many conversion tools.2. The music size is limited. It seems that it cannot be larger than KB (it cannot be too large), and the start music of Win2000 is only 154kb.3. paste the prepared music to c: \ winnt \ Media (Single System Win2000 is used as an example)4.

The following is how it works: The desktop window "Clears" the cropping object. Next, draw the Child Window of each window, first draw the top, at the bottom of the painting. After each window is drawn, add its screen rectangle to the cutter, this area is effective

For example, you want to change your own icons for your program, use some lively cursors to increase interest, play some sound and animation files, or use a program written by others to implement a function. We often want to put these resources directly in the EXE file to form a separate executable file, which leads to a problem of how to access and use

Early StageLameThe ISO encoding technology is used, but the psychological audio model (LameGpsycho) has been fully developed independently and has nothing to do with other companies' technologies. The most important thing is free software. Iii. Essentials of rail capturing First, we need to compress the CD to MP3 and save it as WAV. It is very complicated and troublesome to compress the CD into

Delphi is an excellent visual programming tool of Inprise (formerly Borland). Its built-in Mediaplayer control is a powerful tool for developing multimedia. You can use it to create a program that can play multimedia files like the interpreter in just a few minutes. But few people may know that it can also be used as a recording program.Run Delphi and drag a Mediaplayer control to the form on the System page. The default name is Mediaplayer1. because our program uses its own button, set the Visi
