Core Capabilities

Audacity allows users to record live audio through a microphone, mixer, or other digital input devices. It supports sample rates ranging from 16-bit to 32-bit float, enabling professional-grade sound capture. Users can also digitize physical recordings from cassette tapes, vinyl records, or minidiscs.

The software is primarily known for its extensive editing suite. Users can:

• Cut, copy, paste, and delete audio segments with sample-level precision.
• Arrange multiple audio tracks simultaneously to create complex mixes or podcasts.
• Apply built-in effects such as noise reduction, equalization, compression, reverb, and normalization.
• Alter audio pitch without changing tempo, or adjust playback speed independently.
• Expand functionality through third-party plugins, including VST, LV2, AU, and LADSPA formats.

File Support and Compatibility

Audacity supports importing and exporting a wide variety of standard audio formats, including WAV, AIFF, MP3, AU, FLAC, and Ogg Vorbis. With optional libraries such as FFmpeg installed, users can also work with specialized or proprietary formats like AC3, M4A, and WMA, as well as extract audio directly from video files.
