Audacity

Audacity is an easy-to-use, free, open-source, cross-platform audio editing software.

Audacity is designed to meet the needs of any audio professional, whether a voice-over operator, sound designer, or music producer. It has applications for macOS, Windows, Linux, GNU, and more.

You can download an audio file or record one via a microphone or mixer for editing on the desktop application.

Audacity offers 16-bit, 24-bit, and 32-bit sound processing and uses high-quality resampling and dithering to convert original sample rates and formats. In addition, it performs real-time conversion so that tracks with different sample rates or formats can be combined seamlessly. It's the perfect tool for recording the voiceover for your next marketing video or the "hit" your music career needs.

With Audacity, you can cut, copy, paste, delete, import, and merge sound files. The "envelope tool" function allows you to increase or decrease the volume smoothly. Leverage sound effects to induce tones, silence, noise, instruments, or rhythm tracks. The sound effects also allow you to change the tempo without altering the pitch, and vice versa.

Locate the exact portion of the sample to edit by "scrubbing and searching" or using the Timeline Quick-Play. The "draw tool" function makes it easy to edit individual sample points.

With Audacity, you have an unlimited number of "redo" options. You can undo as many steps as needed.

Activate the spectrogram display mode to make it easier to view and select frequencies and ensure first-rate audio analysis. The Plot Spectrum window allows detailed frequency analysis during editing. You can also export your recordings in many different file formats, including multiple files at once.

Audacity also makes it easy for audio editors to fully manipulate the tool and perfectly edit tracks using the keyboard and providing a series of keyboard shortcuts.
