Software function

Recording and importing: You can record live via microphone or line input, supporting simultaneous recording of up to 16 channels. In addition, it can also transcribe audio from external media such as cassette tapes and records, or capture streaming audio directly from your computer. The software can import and edit audio files in a variety of mainstream formats, such as WAV, AIFF, MP3, OGG Vorbis, etc.

Editing and processing: Audacity provides unlimited undo and redo functions, allowing you to experiment without worrying about mistakes. Its multi-track editing capabilities allow you to mix and edit multiple audio tracks. The unique "zero-crossing point" editing function can automatically adjust the editing point to the zero point of the audio waveform, effectively avoiding popping sounds or noise during cutting.

Effects and plug-ins: The software has built-in rich audio effects, such as "pitch change" to change the pitch, "speed change" to adjust the speed, "noise reduction" to remove background noise, as well as echo, equalizer, etc. It also supports unlimited expansion of its functionality by loading third-party plug-ins such as LADSPA and VST.

Analysis and export: In addition to waveform graphs, Audacity also provides spectrogram mode, which allows you to visually analyze and edit audio from the frequency dimension. When exporting audio, you can create WAV files suitable for burning CDs, or export MP3 files by installing additional LAME encoding libraries.
