AUDACITY - THE #1 WORLD'S MOST POPULAR RECORDING SOFTWARE
Both Windows and MacOS versions are included!
Recording:

- Timer Record and Sound Activated Recording features.
- Dub over existing tracks to create multi-track recordings.
- Record at very low latencies on supported devices on Linux by using Audacity with JACK.

- Record at 24-bit depth on Windows (using Windows WASAPI host), Mac OS X or Linux (using ALSA or JACK host).
- Record multiple channels at once (subject to appropriate hardware).
Import and Export:
- Import and export WAV, AIFF, AU, FLAC and Ogg Vorbis files.
- Fast "On-Demand" import of WAV or AIFF files (letting you start work with the files almost immediately) if read directly from source.
- Import and export all formats supported by libsndfile such as GSM 6.10, 32-bit and 64-bit float WAV, RF64, and U/A-Law.
- Import MPEG audio (including MP2 and MP3 files) using libmad.
- Import raw (headerless) audio files using the "Import Raw" command.
- Create WAV or AIFF files suitable for burning to audio CD.
- Export MP3 files with the optional LAME encoder library.
- Import and export AC3, M4A/M4R (AAC) and WMA with the optional FFmpeg library (this also supports import of audio from video files).
Sound Quality:- Supports 16-bit, 24-bit and 32-bit (floating point) samples (the latter preserves samples in excess of full scale).
- Sample rates and formats are converted using high-quality resampling and dithering.
- Tracks with different sample rates or formats are converted automatically in real time.
Editing:
- Easy editing with Cut, Copy, Paste and Delete.
- Find the spot to edit easily with scrubbing and seeking or Timeline Quick-Play.
- Unlimited sequential Undo (and Redo) in the session to go back any number of steps.
- Edit and mix large numbers of tracks.
- Multiple clips are allowed per track.
- Label tracks with selectable Sync-Lock Tracks feature for keeping tracks and labels synchronized.
- Draw Tool to alter individual sample points.
- Envelope Tool to fade the volume up or down smoothly.
- Automatic Crash Recovery in the event of abnormal program termination.
Accessibility:- Tracks and selections can be fully manipulated using the keyboard.
- Large range of keyboard shortcuts.
- Excellent support for JAWS, NVDA and other screen readers on Windows, and for VoiceOver on Mac.
Effects:- Real-time preview of LADSPA, LV2, VST and Audio Unit (OS X) effects.
- Plug-in Manager handles plug-in installation and addition/removal of effects and generators from the menus.
- Change the pitch without altering the tempo (or vice-versa).
- Remove static, hiss, hum or other constant background noises.
- Alter frequencies with Equalization, Bass and Treble, High/Low Pass and Notch Filter effects.
- Filter a frequency selection made in Spectral Selection views or Spectral Selection Toolbar using spectral edit effects.
- Adjust volume with Compressor, Amplify, Normalize, Fade In/Fade Out, Crossfade Clips, Crossfade Tracks and Adjustable Fade effects.

- Experimental modules that extend the functionality of Audacity.
- Links for many plugins are provided on the CD.
Analysis:
- Spectrogram view modes for visualizing and selecting frequencies.
- "Plot Spectrum" window for detailed frequency analysis.
- "Sample Data Export" for exporting a file containing amplitude values for each sample in the selection.
- Contrast Analysis for analyzing average RMS volume differences between foreground speech and background music.
- Support for adding VAMP analysis plug-ins.
