    1.0 following instructions works if you are using windows
    1.1 Search up cmd in 开始. Click 以管理员身份运行
    1.2 Redirect the directory to the folder of the project. Search on web if you don't know how, it's easy
    1.3 type in cmd: python tryinitffmpeg.py
2. Make sure your proxy/VPN is off if crawling from bilibili, make sure proxy/VPN is on if crawling from YouTube
3. Input the BV num on the top entry if you are crawling bilibili. Input the v num / list num if Youtube
    3.1 If you don't know what the numbers are, click the '?' button beside
4. Input the output directory in the following entry textbox. If you leave it blank, it will be outputted in the default folder.
    4.1 You can click on the '?' beside it to see which folder will be the output for default.
    4.2 Do not leave " or ' on the ends of the directory, or else, there may be errors
5. Input the p_numbers of videos you want in the next 2 entry boxes. 
    5.1 This stands for simply the P number (分P) in Bilibili or episodes in lists for YouTube.

How to use Audio Edit:
1. Run file TryInitFFmpeg.py (which is in the same folder) with admin authority
   (Or directly add the path of ffmpeg in this folder (./ffmpeg-master-latest-win64-gpl-shared/bin) to system path if you are familiar with IT)
    1.0 the following instructions works if you are using windows
    1.1 Search up cmd in 开始. Click 以管理员身份运行 (or for some computers, 搜索 on the left down corner of your screen)
    1.2 Redirect the directory to the folder of the project. Search on web if you don't know how, it's easy
    1.3 type in cmd: python tryinitffmpeg.py
2. open AudioEditGUI and run the program (you should be able to see a tkinter page on your screen)
3. "Audio Path" box
1) if you want to edit only one audio:
- find the file in your folder, and copy its path, then paste it to the box (*replace the original content)
2) if you want to edit multiple audio:
- find the audios you want to edit and put them under the same folder, then, copy the path of the folder and paste it to the box (*replace the original content)
4. "Audio Output Path" box:
1) leave it blank if you want the program to output the editted file into a folder caller "extracts" under the same path as your input
2) find the folder you want it to output to and copy paste its path into the box
5. "Length Edit" boxes:
- there are two boxes in total, which marks the start second of your intended clip and the ending second (for ex. 0s~10s for a clip of 10 seconds) 
- beware that the numbers have to be within the time length of your audio (which you can check by playing your audio)
- for convinience, you can input -1 to the second box to set the ending second to be the end of the original audio, and 0 for the first box to start from the very beginning
6. "Loop" box:
- after editing the length, you can let the clip loop for multiple times by typing a positive integer into the box (for ex. looping a clip with 10 seconds for 2 times results with a 20 seconds long audio)
*beware that the looping function works after the length edit, so your clip resulted from the previous Length Edit will loop

        label = tk.Label(frame, text='''Instructions for to use the widget:
7. "Speed Up" box:
- input a positive number (does not have to be integer) to change the speed of the clip (for example input 2 for double the speed and input 0.5 for half the speed, similar to the changing speed function you see in Bilibili and Youtube)
8. "Volume Edit" box:
- works the same as the previous "Speed Up" box, but with volume
- for the sake of your ear, please make sure you know how loud your audio will be after editting, or else turn down the volume of your computer before listening
9. "Fade In and Fade Out" boxes:
- The fisrt box is for how many seconds the audio starts from 0 audio and gradually increase volume till it reaches the original volume to make the audio more start and end more smoothly(ex. Fade in 2 seconds, Fade out 3 seconds)
- beware that this works after all the above functions (length, loop, speed up, volume)
10. "3D Sound Effect" box:
