Edit a video without using a mouse or trackpad. Build a presentation without seeing the screen. Or track down important files for your next project with just your voice. Because Mac is designed for everybody to create amazing things.
Means that Audacity team is not bounded Section 508 since audacity develepment team is not Federal agency (??). OK, perhaps schools are bound 508 but their servis consists of many components that complement each other which is an adventage. Unfortunately, Audacity 2.1.2 is not accessible for users of VoiceOver, and this was also the case for the Audacity 2.1.1 release. However, an accessible version of Audacity 2.1.1 is available on our Mac OS X downloads page. The name of this accessible version is '2.1.1-screen-reader' (DMG and ZIP downloads are available). Does Audacity work with screen-reader programs for blind users? What features does Audacity have for speech transcription or speech recognition? Does Audacity run on 64-bit systems?
VoiceOverYou don’t need to see your Mac to use your Mac.
VoiceOver is a revolutionary built-in screen reader that’s more than a text-to-speech tool. It tells you exactly what’s on your screen and talks you through actions like editing a video, building a presentation, or quickly navigating from one app to another.
Dark ModeWorking hard gets easier on the eyes.
Dark Mode transforms the desktop and built-in apps with a new dark color scheme that helps you focus on your work.1 The fine points of your content take center screen as toolbars and menus recede into the background. Light text against darker backdrops in Mail, Safari Reader, Calendar, and more makes everything easier to read in low lighting conditions. And the Accessibility preferences for increased contrast and reduced transparency work with Dark Mode enabled.
SiriMake requests by talking or typing.
Siri on Mac lets you quickly find and open files, set reminders, send text messages, and more, making it easy to handle the things you do every day.2 With “Type to Siri” mode, you can make requests using a physical or onscreen keyboard. And Siri can also predict your next word based on what you’ve said before, so you can minimize typing over time.
Switch ControlNavigate your Mac with as little as a tap.
Create amazing things with your Mac without touching a mouse or keyboard. With Switch Control, you can navigate through onscreen keyboards, menus, and the Dock using a variety of switch options.
Text to SpeechGo from written word to spoken word.
If you learn better when you can hear what you’re reading or writing, Text to Speech lets you highlight any text and have your Mac read it aloud. And you can choose from more than 70 male or female voices across 42 languages.
What Is Audacity Program
Audacity, according to the developers, is a “free, open source, cross-platform software for recording and editing sounds.” This means that we can all work together, regardless of our preferred operating systems, to participate in the art of creating and editing audio. And Audacity supports plugins! Plugins are amazing, wonderful things, especially when the base program itself is amazing.
When compared to the commercial competition that can cost upwards of $800 and is restricted to Windows-only platforms, why shouldn’t we give Audacity a shot?
Who should use Audacity?
Audacity is great for anyone who wants to record and edit audio, but it’s not that great for recording music. Audacity is not a multi-track recorder. It can only record two channels at a time, left and right. If only one instrument is being recorded at a time, Audacity works fine. People who want multi-track recording should probably take a look at Ardour.
Now that we know what Audacity is not for, here are some projects that Audacity excels at:
Screen Reader For Windows 7
- Voice acting – People have been known to use Audacity on Fiverr to get started.
- Audio Books – The librevox project recommends Audacity to their volunteers.
- Screen cast tutorials – Sure, screen recording software can typically capture voice, too, but it’s nice to edit voice separately from sounds produced on the computer.
- Let’s plays – Similar to screen casting, using Audacity to record commentary separate from in-game audio makes post-production less of a nightmare.
Installation
Audacity is available for Windows, Mac OS X and Linux. It is available in most Linux distribution’s repositories, so you can easily install it directly from your package manager. In Ubuntu you can install it from the Software Center or just run the following command:
For those Ubuntu users who want the bleeding edge Audacity experience, feel free to add the audacity team ppa to get a daily build:
A word of warning: while daily builds can showcase the most up-to-date features, they may also contain catastrophic bugs and are generally not recommended for use in a production environment.
Configuration
After everything is nicely installed and running, the first thing we need to do is check the Preferences to make sure our audio devices are correct. To do this we will go to “Edit -> Preference.s”
The defaults should be fine, but let’s say we have a Blue Yeti Pro USB microphone plugged into a laptop. Audacity’s default will most likely be the laptop mic. To fix this we need to click the recording device’s drop-down menu and select the one that says, in this case, “Blue USB Audio.” Other USB microphones should have a similar listing.
Note: USB microphones must be plugged in prior to Audacity being started for Audacity to recognize them.

For those who are using a cheap 3.5mm microphone, choose the “Analog” option. In the case of the more professional XLR mics, special equipment is needed to interface the microphone with the computer and is beyond the scope of this guide.
Usage
Audacity Download Mac Os X
Audacity is one of those things that is easy to start but difficult to master. Since we already have Audacity installed and the mic setup, all we need to do is hit Record (the big red Record button at the toolbar) and start talking.
When we’re done recording, we click stop, and the wavelength of our voice will show up in Audacity. If we click Record again, Audacity will play the track we already recorded while simultaneously recording a new one. This is incredibly handy for musicians trying to add another instrument to a mix.
To visualize recordings is useful even from a basic perspective. Particularly, we can even use it to leave a note for ourselves.
Audacity Software For Mac
So there we are, reading a passage from some short story, and we mess up on the second paragraph. To make it easy on ourselves we clap, or make some other loud noise, to cause a spike as shown in the second recording in the above image. Now when we come back and edit the audio, we can easily find the place where we made the mistake and edit it out.
All we have to do is click somewhere in the audio, hold “Shift,” click somewhere else and we will have a section highlighted. From here we can cut/copy/paste, play the selection, or add some sort of effect. To make things easy, the team behind Audacity decided to use shortcuts many of us are familiar with from using file managers. Some examples:
- Ctrl + x – Cuts a selection of audio
- Ctrl + v – Pastes a selection of audio
- delete – Deletes, as expected
Plug-ins and special effects
It would be insane to try and go through all of the plugins and special effects of Audacity, so we are going to focus on two major ones.
First, the ability to relatively easily filter out background noise. Derrik Diener wrote a great piece on how to do this last year.
To make things a little easier, we need to be sure to have five to ten seconds of empty audio at the begging of the track.
Why? The preview button will play the first five seconds of audio on the track, and it’s a lot easier to listen for background noise when there are no other distracting sounds.
At the end of his article, Derrik did mention the use of normalization to make audio sound better. While this works, the librevox project recommends replaygain, which aims to get volume as close to 89 dB as possible.
This is particularly important for serialized content such as let’s plays, where we don’t want our voice to be louder or quieter video to video.
