Is there any software that can adjust the tempo fast or slow?

VideoStudio, Adobe Audition, etc., both of which are more mainstream.

But now the genuine one seems to cost money?

FL Studio12 tutorials.

1. Open the software settings for the first time.

System Settings window. The window will pop up when we open the software for the first time, if it doesn't pop up we can press and hold the keyboard key "F10", and then we can choose the sound card and MIDI driver we need. We'll look at the MIDI settings window first, but the most important one is the audio settings window.

1. We can select the output driver in the drop-down menu. If you're not sure which one to choose, you can choose the default system driver. If you feel that there is a problem with the output sound, you can re-select a different driver.

2. Buffer length. We don't need to know much about this window, but I need to grasp the basic purpose of buffer length. Generally speaking, if the buffering setting is long, the possibility of outbursts will be greatly reduced, but the response speed of playback will be reduced; If the settings are short, you can get a faster response, but there is a risk of loud noises.

We certainly want it to be as short as possible, but it depends on your computer. If your computer's sound card is good and fast, we can set it to 10ms. The innovative SoundBlaster Live sound card allows us to set it down to 30ms.

3. In addition, if you want to improve the response speed of the operating system, we can use the use polling option, provided that you are using Windows 95 or 98, but if you are using Windows 2000, it is better not to open the main window. Once the settings are complete, we can see the main window, which is the start screen of FL Studio. You'll find that FL Studio's interface is made up of a lot of large and small windows nested together.

Above the main window is the toolbar. Inside the large window are the Browser (left) and the Beat Sequencer (right). We can freely arrange the window position according to our needs.

2. Simple production and saving output:

2. Open the piano window interface, enter the notes, and then play your own ** cells and improvise.

3. You can open another instrument on another track and enter it again. A variety of ** is combined to make a simple song.

4. Output, when the production is completed, you need to output, click Export in the window file, usually in *** format. Or output it in the format you need.

It's okay to listen quietly with a thousand thousands.

Use the audio recorder software that comes with the XP system to do the trick.

With Format Kid, you can speed up or slow down the speed of the songs available in the Apple Store.

You can use the audio recorder software that comes with the XP system, which is very convenient.

[Specific operation method] (take slowing down as an example).

Open the audio file you want to change, select"Effects - Time & Pitch - Stretch & Pitch Shift"

In the pop-up window, you can see that the default time is 4:49

Click OK to make it a slower**.
