- 1Features and usage
Features and usage[edit]
- Audacity is a free, easy-to-use audio editor and recorder for Windows, Mac OS X, GNU/Linux and other operating systems. You can use Audacity to: Record live audio. Convert tapes and records into digital recordings or CDs. Edit Ogg Vorbis, MP3, WAV or AIFF sound files. Cut, copy, splice or mix sounds together. Change the speed or pitch of a.
- Mar 29, 2019 How to Manually Auto Tune With Audacity. This wikiHow teaches you how to apply an auto-tune effect to vocals in Audacity. You'll use a free plug-in called 'GSnap' to do so. Contrary to popular belief, GSnap is available for both Windows.
Audacity's main panel annotated. All the components that have been labelled are custom for Audacity.[12]
In addition to recording audio from multiple sources, Audacity can be used for post-processing of all types of audio, including podcasts by adding effects such as normalization, trimming, and fading in and out.[13] Audacity has also been used to record and mix entire albums, such as by Tune-Yards.[14] It is also currently used in the UK OCR National Level 2 ICT course for the sound creation unit.
Audacity's features include:
- Four user-selectable themes enable the user to choose their preferred look and feel for the application (version 2.2.0 and later)[15]
- Four user-selectable colorways for waveform display in audio tracks (version 2.2.1 and later)[16]
- Recording and playing back sounds[17]
- Scrubbing (Version 2.1.1 and later)[18]
- Timer Record [19] enables the user to schedule when a recording begins and ends to make an unattended recording.
- MIDI playback is available (from version 2.2.0 onwards)[20]
- Punch and Roll recording - for editing on-the-fly (from version 2.3.0 onwards)
- Editing
- via cut, copy, and paste, with unlimited levels of undo[21]
- Features of modern multitrack audio software including navigation controls, zoom and single track edit, project pane and XY project navigation, non-destructive and destructive effect processing, audio file manipulation (cut, copy, paste)
- Amplitude envelope editing[22]
- Precise adjustments to the audio speed (tempo) while maintaining pitch in order to synchronize it with video or run for a predetermined length of time[23]
- Conversion of cassette tapes or records into digital tracks by splitting the audio source into multiple tracks based on silences in the source material[24]
- Cross-platform operation — Audacity works on Windows, macOS/OS X, and Unix-like systems (including Linux and BSD)[25]
- Audacity uses the wxWidgets software library to provide a similar graphical user interface on several different operating systems.[26]
- A large array of digital effects and plug-ins.[27] Additional effects can be written with Nyquist, a Lisp dialect.[28]
- Built-in LADSPA, VST(32-bit) and Nyquist plug-in support[29]
- Noise Reduction based on sampling the noise to be minimized.[30]
- Vocal Reduction and Isolation for the creation of karaoke tracks and isolated vocal tracks.[31]
- Adjusting audio pitch while maintaining speed and adjusting audio speed while maintaining pitch[32]
- LADSPA, VST (32-bit) and Audio Unit (macOS/OS X) effects now support real-time preview (from version 2.1.0 onwards). Note: Real-time preview does not yet support latency compensation.[33]
- Saving and loading of user presets for effect settings across sessions (from 2.1.0 onwards).[34]
- Multitrack mixing[35]
- Support for multi-channel modes with sampling rates up to 96 kHz with 32 bits per sample[36]
- Audio spectrum analysis using the Fourier transform algorithm[37][38]
- Importing and exporting of WAV, AIFF, MP3 (via the LAME encoder, now integrated as part of Audacity), OggVorbis, and all file formats supported by libsndfile library. Versions 1.3.2 and later supported Free Lossless Audio Codec (FLAC).[39] Version 1.3.6 and later also supported additional formats such as WMA, AAC, AMR and AC3 via the optional FFmpeg library.[40]
- Detection of dropout errors while recording with an overburdened CPU
- From 2.3.2 onwards, mod-script-pipe for driving Audacity from Python now comes with Audacity and it can be enabled via preferences.
- A full downloadable Manual[41](or available online without downloading).
Audacity supports the LV2 open standard for plugins and can therefore load software like Calf Studio Gear.[42]
Limitations[edit]
Audacity supports only 32-bit or 64-bit VST audio effect plug-ins, depending on which architecture it was built for, but not both at the same time. It does not support instrument VST (VSTi) plugins.[43]
Audacity lacks dynamic equalizer controls and real time effects while recording.
Audacity does not natively import or export WMA, AAC, AC3 or most other proprietary or restricted file formats; rather, an optional FFmpeg library is required.[44]
Language support[edit]
In addition to English language, the Graphical User Interface of the Audacity software program is translated into Afrikaans, Arabic, Basque, Bulgarian, Catalan, Chinese (simplified), Chinese (traditional), Czech, Danish, Dutch, Finnish, French, Galician, German, Greek, Hungarian, Irish, Italian, Japanese, Lithuanian, Macedonian, Norwegian (Bokmål), Polish, Portuguese, Romanian, Russian, Slovak, Slovenian, Spanish, Swedish, Turkish, Ukrainian, and Welsh.[45]
The documentation, the Audacity Manual, is available only in English.[46] The Audacity Forum offers technical support in: Spanish, French, Russian and German.
Audacity architecture[edit]
Software architecture of Audacity showing how the software is built in layers[12]
The diagram illustrates the layers and modules in Audacity. Note the three important classes within wxWidgets, each of which has a reflection in Audacity. Higher-level abstractions result from related lower-level ones.
For example, the BlockFile system is a reflection of and is built on wxWidgets' wxFiles. Lower down in the diagram is a narrow strip for 'Platform Specific Implementation Layers.'
Both wxWidgets and PortAudio are OS abstraction layers. Both contain conditional code that chooses between different implementations depending on the target platform.[12]
Reception[edit]
The free and open nature of Audacity has allowed it to become very popular in education, encouraging its developers to make the user interface easier for students and teachers.[47]
CNET rated Audacity 5/5 stars and called it 'feature rich and flexible'.[48] Preston Gralla of PC World said, 'If you're interested in creating, editing, and mixing you'll want Audacity.'[49] Jack Wallen of Tech Republic highlighted its features and ease-of-use.[50] Michael Muchmore of PC Magazine rated it 3.5/5 stars and said, 'Though not as slick or powerful as programs from the likes of Adobe, Sony, and M-Audio, Audacity is surprisingly feature-full for free software.'[51]
In The Art of Unix Programming, Eric S. Raymond says of Audacity 'The central virtue of this program is that it has a superbly transparent and natural user interface, one that erects as few barriers between the user and the sound file as possible.'[52]
Several authors criticized Audacity for inconvenient user interface, destructive editing and lack of features, comparing Audacity unfavorably to competing products, which require fewer actions from the user to do tasks such as crossfade and noise reduction.[53][54]

Audacity for Mac is a powerful audio editing tool that surpasses default OS X tools. The downsides are a dated and sometimes clunky interface and a cumbersome installation process.
Pros
Audacity Mac Os
Powerful and robust feature set: Audacity is loaded with audio editing, recording, and exporting tools that work in tandem with Mac's multimedia capabilities.
Audacity
Free with regular updates for diverse uses: Audacity is a free, regularly updated tool with solid support from the developer. This means a solid core that works far better than some other free software suites in the same category, and a good alternative to somewhat limited tools like GarageBand.
Cons
Interface is dated and sometimes clunky: While Audacity's feature set delivers, it looks and feels a little dated compared to more modern software. In most cases this is purely aesthetic, but finding certain menus can be cumbersome in some circumstances. Mac product knowledge manual.
Bottom Line
Audacity Download Mac Free
If you need a powerful, free audio editing tool for your Mac, Audacity is a great tool with which to start. While the interface could use some updates, you'll still get the bang you're looking for in your audio project.
