If you are a professional sound designer or looking to become one, you need to have strong, versatile audio editing software. Audacity has your sound design needs covered no matter what platform you use for your sound design: Windows, Mac OS, and Linux are all compatible. You can import and digitize audio tracks from other devices or record directly into your computer by connecting a microphone and headset – or if you prefer a more direct approach, a MIDI keyboard. The program is free and open-source.
Audacity provides support for three bitrates: 16-, 24-, and 32-bit sound quality. By accessing the Quality Settings tab from Edit -> Preferences, you can change the bitrate. Other options available in this sound mixing program are the ability to detect the BPM of a track and generate a backing track to keep the sound channels in sync.
You get unparalleled customization ability and real-time preview of the various plugins such as LADSPA, Nyquist, Audio Unit, and VST. Some of the customization options include distortion-free pitch and tempo shifting, reversed track, reverb, vocal isolation, and distortion. Feel free to experiment to your liking; unlike other audio editing programs, Audacity gives you unlimited Undo/Redo iterations. For ease of access, Audacity allows you to create and customize a multitude of keyboard shortcuts and macros through the Tools menu. You can perform dozens of operations with a single key press.
The Spectrograph view feature gives you a visual representation of how your sound changes over time, indicated as colored bands to indicate gain at various decibel levels. You can access this view by clicking on an individual track and selecting the appropriate option in the dropdown menu that appears.
These are just a few of the features that Audacity offers to sound engineers, and you can also create your own plug-ins using text editor programs.
