This page is an overview of the key new functionality that has been introduced in Audacity 2.1.3
Gale 02Dec16: The intro looks silly with larger text size, IMO. If we want larger text size, which perhaps we do, I suggest not using the intro template but styling a div with appropriate top and bottom margins like we do on the front page. The "font size" HTML tag is deprecated in HTML 5, so better not to use it if possible.
  • Bill 01Dec2016: At first I was put off by the "we did this" and "we did that" but I now see that this page is half hype and half documentation. As such, those phrases work.
    I've made a few minor changes here and there.
    • Simplified the sentences in the pinned head section
    • Change heading from "Distortion" to "Distortion Effect"
    • Simplify description of "Act when paused"
    • Fix a couple of typos
  • Peter 01Dec16: Thanks for the feedback Bill. And yes this is partly intended to be a marketing "puff piece" designed to get folk interested in and excited by the new functionality - hence the "we did this" and "we did that".
  • Peter 01Dec16: Gale suggested by email: DISPLAYTEXT that says "New features in <version number> on this page.

Transport improvements

Pinned play/record head

We have implemented the long-standing and popular feature request of a fixed and centered play/record head (called the "pinned head"). When the pinned head is selected the waveform scrolls continuously past the fixed head while you are playing or recording.

The pinned head can be selected by using the new button at the left of the Timeline. By default this is the familiar green downwards-pointing triangle (like the playhead) and the default behavior is the old familiar scrolling play/record head. The pinned head can also be selected in Tracks Preferences.

When pinned playback or recording is chosen, the playhead displays as a green drawing-pin (as shown in the image below) and the recording head displays as a red drawing-pin.

Clicking the drawing-pin reverts to default unpinned playback and recording, and the button will change back to the green triangle.

Scrubbing

For this release we have changed the way in which scrubbing works.

We have introduced a new Scrub Ruler which is on by default and sits just under the Timeline. You can turn it on or off from the right-click dropdown menu of the Timeline.

If you hover the mouse over the Scrub Ruler you will see the Scrub widget's green left- and right-pointing arrows Scrub icon naked 80%.png appear (along with a tooltip if you continue to hover). Clicking anywhere in the Scrub Ruler, releasing the mouse button then moving the mouse left or right will start Scrubbing from there. Note that in this image the green scrub widget is to the right of the green triangle playhead, indicating that forwards scrubbing towards the pointer is taking place.

To stop scrub play and set the cursor at the current playback position, just click the Stop button The Stop button (or its shortcut SPACE).

There is also a Scrub Toolbar Scrub Toolbar 60%.png which is off by default, but you can enable it at View > Toolbars. This toolbar gives you button access to the scrubbing and seeking transport commands and facilitates turning the Scrub Bar on/off.

Timer Record

We have added some new features to improve Timer Record.

You can now specify optional actions on completion such as Save and/or Export, quit Audacity and, on Windows, shut down.

Audacity will now warn you in advance if it calculates that you have insufficient disk space for the length of your scheduled recording.

Peter 01Dec16: I decided not to include this here

Effects and Generators

Stop and Do if paused

A big improvement you will notice is that all effects plus edits and other functionality can now be actioned from paused state - Audacity will stop the audio and do the action or open the dialog requested. This should remove a common cause of confusion for our users.

Distortion Effect

We have introduced a new Distortion effect (which supersedes the "Leveller" and "Hard Limiter" effects found in earlier Audacity versions). Technically this effect is a waveshaper. The result of waveshaping is equivalent to applying non-linear amplification to the audio waveform. Preset shaping functions are provided, each of which produces a different type of distortion. Presets are provided which suggest typical settings for a wide range of uses.

Rhythm Track

The former Click Track generator has been updated and renamed to Rhythm Track with improved sounds and a new "Swing amount" control for unequal beat duration.

Sample Data Import

We have added a new Generator for Sample Data Import which reads numeric values from a plain ASCII text file and creates a PCM sample for each numeric value read.

Keyboard Shortcuts

There are two new keyboard shortcuts to navigate between labels: ALT + RIGHT to Move to Next Label and ALT + LEFT to Move to Previous Label. Use these shortcuts to move the editing position to the label, without opening the label for editing. If audio is already playing, playback jumps to the label requested, which is useful if you have split a recording into separate tracks using labels.

These new shortcuts also let screen readers for the blind read the label's name and its order in the labels in that track, a feature lacking in Audacity until now. There are no corresponding menu entries or buttons for these shortcuts.

New menu items

Edit Menu

There are two new commands to aid making selections:

  • Use Edit > Store Cursor Position to store the position of the editing cursor (or when there is active audio, to store the position of the playback or recording cursor).
  • Subsequently, use Edit > Select > Cursor to Stored Cursor Position to select from the editing cursor (or during active audio, from the position of the playback or recording cursor) to the stored cursor position.
If you want to use these commands during playback or recording, it's best to either pause playback or recording at the correct place, or add shortcuts for these two commands.

Tracks Menu

Another new menu item is Tracks > Type to Create a Label (on/off). Previous Audacity already let you type to create a label in the focused label track, but this feature made it easy to accidentally create a label when you really wanted to use shortcuts to play or act on the audio. Uncheck this new menu item (or make the same change in Tracks Preferences) to avoid that risk.

Audacity Tour Guide

We have added Audacity Tour Guide to this Manual. It tells you about a few of the core Audacity features and about some of the more specialized features you might not know where to find.

Ed 01Dec16 : I do not like that last sentence "It tells you…" Might I suggest something more along the lines of:

"It gives you a brief overview of some of Audacity's more important features and acquaint you with some of the more common controls."

  • Gale 02Dec16: Somewhat modified. The main reasons for James's Guide were a possible source of ad revenue as a separate download, and to point users to already existing features that are often requested in Forum and [email protected] To me, it is a partial duplication of "Getting Started" and the only additional value in the Manual is the "not known about" features.
  • Ed 2Dec16 : I'm happy with this now.
  • Peter 02Dec16: the difference between the Tour Guide and the Getting Started is that the Tour Guide is really an advert for what we have got, things that users mighht have overlooked (even experienced users) a bit of a marketing "puff piece" like this new "New Features" page. In contrast the Getting Started is a How To do stuff for beginners. Inevitably there will be a little overlap in content (just as there is with this page and the Release Notes) but the purpose of both pages is fundamentally quite different (again, just as there is with this page and the Release Notes).
