Audacity

Audacity is an audio editor and recorder available for Windows, macOS and Linux operating systems.
You can use it to:

Record live audio
Convert records/tapes into digital format
Mix multiple audio sources together into a multi-track project etc

If you are now starting to work with audio, and you need some basic skills to record and edit files, Audacity with its tools is a good option.

Why Audacity?

Simple to use and lightweight
Has several tools and functions that cover your basic needs in editing
Its price is free
It is FOSS - free and open-source software

Free and Open-Source Software

Audacity is free, open-source software. You are free to use it for any personal, commercial, or educational purposes, including installing it on as many different computers as you wish. You are also free to give it away, sell it, or modify it for your own use, under the terms of the GNU General Public License.
The authors of Audacity decided to release it under the GPL for many reasons. Some do so out of generosity. Some do it for moral reasons because they believe that all software should be free;
Audacity being free means also that it will be more popular and useful. Another reason is to encourage collaboration. Because of Audacity's free license, multiple people worldwide have contributed code, bug fixes, documentation, and graphics.
Like other FOSS, it has online documentation and a community you can participate (ask questions, exchange knowledge etc).

Basics

Download and install Audacity

https://www.audacityteam.org/
DOWNLOAD AUDACITY button (It will download the latest version of Audacity)
Choose the operating system you are using. (Windows, macOS, GNU/Linux)
Follow the installation instructions

Import audio

Import existing audio into Audacity. Can open many of the most common file formats like WAV, AIFF (uncompressed audio formats) or MP3, Ogg Vorbis (compressed audio formats) etc.
1. File > Import > Audio...
If you select the File > Import > Audio... command, then choose one or more audio files, Audacity will import the selected file(s) into the existing project. This is useful to bring the content of one or more audio files into a project that already contains audio (for example, to mix several audio files together).
2. File > Recent Files (Open Recent on Mac)
This command imports a single file from a list of the 12 most recently imported files or recently saved projects. The file opens in a new window exactly as File > Open....
3. Drag and drop files into an open Audacity Project window.

Select and Zoom

Waveform: Audio in Audacity shows up as a Waveform. These jagged lines of peaks and valleys (high and low points) make up the waveform.

This is the visual representation of sound waves; time is represented horizontally from left to right, and the loudness of sound is represented vertically.
The louder the sound, the taller the waveform.

Mono & Stereo files: In stereo, we can have separate audio in the left and right channels. In mono, there is only a single channel and you hear the same audio on both left & right sides.
Mute & Solo
Start, stop, pause: Play button or Spacebar to start and stop! Pause button or (p) key to pause.
Selection tool: default tool to work with waveforms. Allows you to select specific sections. Eg you may need this to focus on editing a specific part or remove the selected part. Adjust the selection by holding (shift) or moving the cursor at the edges of the selection.
Zoom tool: Lets you zoom in specific sections of the waveform by clicking. Helps for precise editing, like chopping a word or a breath and reorganising them. Zoom out by holding (shift) and clicking. To view the whole project as a whole, you can click the "Fit project to width" button. To zoom vertically: View->Zoom->Advanced Vertical Zooming and click on the left side of the waveform.
