Audacity 1.3 -howto

Audacity 1.3 Setup and Configuration http://manual.audacityteam.org/index.php?title=Audacity_Setup_and_Configuration To record: 1. Set Recording Device either in the Devices tab of Preferences („Bearbeiten (Edit) > Einstellungen (Preferences) > Geräte (Devices)" ) or in Device Toolbar.

Device Preferences lets you choose stereo recording if required.

2. Set input source for that device (for example, microphone or line-in) in the dropdown selector of the Mixer Toolbar, 3. Adjust input level using the right-hand slider on the Mixer Toolbar.

Adjusting and monitoring recording level

Use the input volume slider on the Mixer Toolbar to adjust the level of audio being recorded. In the image above, note that the blue lines in the recording meter (indicating the maximum peak level attained) are at about -6 dB.

Recording a New Track Every time you click the Record button Audacity will create a new track and begin recording on that track from the current cursor position.

If you want recording to start from the beginning of the new track, click the "Skip to Start" button on the Control Toolbar.

Continuing Recording on an Existing Track If you want to continue recording on an existing track instead of starting a new track you have two options.

1. Instead of clicking the Stop button to end recording, click the Pause button to pause recording. Click the Pause button again to continue recording.

2. Select the track you want add the recording to and, while holding down the SHIFT key, click the Record button. This is called "Append Record".

Audio selection You select both the tracks and the time range simultaneously, by clicking and dragging. Make sure you're using the Selection tool !

To change the selected time range, you have several options: • •

Move the mouse cursor to one of the edges of the selection until it changes to a different pointer. Click and drag to change that edge of the selection.

Shift-click near one of the edges of the selection to extend or contract the selection to the time point you clicked on.

The Edit menu provides the standard edit commands (Undo, Cut, Copy, Paste and Delete) plus many other commands specific to editing audio:

Track Start to Cursor Selects a region in the selected track(s) from the start of the track to the cursor position.

Cursor to Track End Selects a region in the selected track(s) from the cursor position to the end of the track.

Tracks (Tonspuren) All audio files that are imported, or new audio that is recorded, goes into a new track.

Many track properties can be accessed by clicking the title of the track, near the upper-left corner, bringing up a menu something like this:

Stereo Tracks Stereo Tracks contain a single label area to the left with two waveforms on the right. The top waveform represents the left channel and the bottom waveform represents the right channel:

By default, the two channels of a stereo track are always edited simultaneously. However, you can split them apart and work with them independently by opening the track menu (see above) and selecting “Split Stereo Track�.

Splitting a track into clips allowing you to manipulate the clips independently.

As an example, see what happens when you select Edit > Split:

This splits the current clip into three clips at the selection boundaries.

Time-shifting clips To move clips around independently, use the Time Shift Tool When you click on a clip and drag it to the left or right, this is called time-shifting, because you are changing the time that audio will be heard.

Tools Toolbar Tools Toolbar allows you to choose various tools for selection, volume adjustment, zooming and time-shifting of audio.

Selection F1 Click to select a start point for audio playback, or click and drag to select a range of audio to play or edit. You can also create a selection area between two points by clicking at one point, then holding down SHIFT while clicking at the other point.

Envelope (H端llkurvenwerkzeug) F2 Allows smooth volume changes to be made over the length of a track by means of embedded volume "control points". Click in the track to create a control point, then set the volume of that point by dragging one of its four vertically arranged "handles". Dragging an inner handle allows you to amplify a quiet piece of audio beyond the original volume envelope of the track.

Time Shift (Zeitverschiebungswerkzeug) F5 Selecting this tool lets you synchronize audio in a project by dragging individual or multiple tracks or clips left or right along the timeline. Also use this tool to drag individual tracks or clips up or down into another track. Note: dragged audio cannot paste into other audio, so the area being dragged into must have sufficient space to accommodate the drag.

Multi F6 Combines all five tools in one. One tool is available at a time, according to the mouse position.

The shape of the cursor changes to show which tool is active. (linke Maustaste zum Markieren, rechte Maustaste zum Zoomen)

Envelope Tool (H端llkurvenwerkzeug) F2 The volume is directly proportional to the height of the waveform - the smaller you make the waveform, the quieter it will sound:

An amplitude envelope is manipulated by a number of control points. Each control point is visible by its four handles (the small circles in the image above), by which you can drag the point up or down to control the volume level.

Adding and editing Control Points Just click the mouse button anywhere in a track to create a new control point.

The audio will always change smoothly between each control point, so you only need to add as many as are necessary. You can click in either the top or bottom half of a track to create a new point. If you have a stereo track, the same envelope will apply to both channels.

Removing control points To remove a control point, click on any one of its control points and drag it outside the track.

Extra amplification If you are amplifying a quiet passage, you can amplify outside the original volume envelope of the track by grabbing either of the inner control points. When you do this, Audacity can't display the full shape of the envelope, and changes the border to a dotted line in the affected area:

Track gain control Totally separate from the amplitude envelope, each track has a gain slider in its Track Panel. This adjusts the volume of the whole track, like Effect > Amplify... can do, but without modifying the waveform itself.

Therefore you don't have to use Envelope Tool to adjust the overall volume of a track use it to specify changes in volume through the course of the track, then you can make fine adjustments to the overall volume with the gain slider.

Rendering envelope changes A lot of volume changes can make a track more cumbersome to work with, so sometimes when you're sure you've got them right, you may want to commit them all and get rid of the control points. To do this, select the track you're finished with and click Tracks (Spuren) > Mix and Render (Spuren zusammenf端hren). This option is sometimes called Bounce in other software.

The resulting track will sound the same but will no longer have its amplitude envelope control points. Naturally you can always add further control points later on, or get all the original control points back by undoing the Mix and Render if you're not happy with it.

Taskleiste: Bearbeiten [Ausschneiden] Wurde ein Bereich in einer Spur markiert, dann kann den mit diesem Befehl entfernen. Wobei sich dann der ausgeschnittene Bereich in der Zwischenablage befindet. Desweiteren schiebt sich der Bereicht, der sich auf der rechte Seite der Markierung befand, in die Lücke (so dass keine Pause entsteht).

[Ausschneiden und trennen] Dieser Befehl ist ähnlich, wie [Ausschneiden]. Einziger Unterschied ist, dass der Rest der Spur unberührt bleibt. Es entsteht also an der ausgeschnittenen Stelle ein Lücke.

[Trimmen (umgekehrt löschen)] Manchmal möchte man nichts ausschneiden, sondern nur den markierten Bereich behalten, so dass der links und rechts von der Markierung befindliche Bereich verschwindet. Mit diesem Befehl ist das möglich. Wobei die Position des markierten Bereichs nicht verändert wird.

[Clip trennen] Dieser Befehlt trennt die Spur an der Stelle, an der sich der Curser in der Spur befindet, so dass sich die Teile links und rechts des Cursors verschieben lassen.

[In neue Tonspur verschieben] Verschiebt den markierten Bereich in eine neu erzeugte Spur. Dabei nimmt der Bereich in der neuen Spur die gleiche Position ein und der ursprüngliche Bereich bleibt leer..

[Clip verbinden] Verbindet innerhalb einer Markierung die Bereiche (Clips). Befindet sich Leerraum innerhalb des Bereiches, so wird der durch Stille ersetzt.

[Detach at Silences] Ersetzt Bereiche innerhalb einer Markierung, die aus Stille bestehen, durch Leerraum. Löscht also Stille.

Label Tracks (Textmarken hinzuf端gen) Suppose that you have a recording of an interview and you want to annotate the questions and answers so you can easily jump directly to a particular question or answer later on. Initially, you may have something like the image below. Without any annotation it's almost impossible to tell them apart just looking at the waveform.

Here, we select the first question with the mouse (below). This may require listening to the audio several times to determine the exact boundaries of the selection.

Now click on Tracks (Spuren) > Add Label at Selection, or type its keyboard shortcut ( CTRL + B). This creates a new label track and a blank label outlining the current selection (below).

The cursor is automatically positioned inside the label, so just type the name of the label and then press Enter. Pressing Enter then allows you to use any current keyboard shortcuts normally, so you could press spacebar to listen to the selection again if you wished. In the image below we've typed Question 1.

http://manual.audacityteam.org

Claude Schmit, Februar 2010

After this question comes the answer from the person being interviewed. We'll select this one by starting from the right side of the answer and dragging to the left. Note that a vertical yellow guide appears when we get to the edge of the first label, making it easy to line up the two labels (below).

It's common for the next label to start exactly where the previous one ends, but it's not necessary.

Once again, click on Tracks > Add Label at Selection to create the next label, then type its name and press Enter. Then in the following image, we've added even more labels.

And here is a complete label track with several labels

http://manual.audacityteam.org

Claude Schmit, Februar 2010

Selecting a label Whenever you click on the title of a label inside the label track, it selects the label and also selects that range of audio in all audio tracks. It also lets you edit the name of the label.

Press TAB to move from one label to the next, and SHIFT+TAB to move backwards.

Deleting labels Click on the label's title to select it, then press the Backspace key on your keyboard until the title is gone. Once the title is empty, press Enter or just press Backspace again to delete the label.

Changing the length and position of labels with the mouse You can change the time boundaries of a label by clicking and dragging the little handles on either side of each label. There are actually two handles on the side of each label, or three where two labels meet. The purpose of these is so that you can either adjust just one label, or two neighboring labels together.

Editing multiple labels at once Sometimes it's useful to edit multiple labels at once using a tabular view, similar to editing a spreadsheet. To do this, click on Tracks > Edit Labels, which brings up a dialog box showing all of your labels:

Taskleiste: Effekte (Auswahl) [Ausblenden] [Einblenden] Dieser Effekt wird direkt angewendet. Dabei wird vom Anfang bis Ende der Markierung die Lautstärke (Volume) geradlinig runter- resp. hochgerechnet.

Alternative (Kurve): [Cross Fade In] / [Cross Fade Out] [Geschwindigkeit ändern] Plattenspieler-Effekt: Beim Ändern der Geschwindigkeit ändert sich gleichzeitig auch die Tonhöhe. Auch die Länge der markierten Auswahl ändert sich dabei.

[Tempo ändern] Dieser Effekt bewirkt ähnliches, wie [Geschwindigkeit ändern]. Der Unterschied hier aber ist, dass sich die Tonhöhe nicht ändert. Die Länge der markierten Auswahl ändert sich dabei.

[Tonhöhe ändern] ändert die Tonhöhe ohne dabei die Abspielgeschwindigkeit zu verändern. Die Länge der markierten Auswahl ändert sich dabei nicht.

[Klick-Filter] entfernt kurze Störgeräusche, z.B. Knackser bei Schallplattenaufnahmen.

[Rauschentfernung] Bedienungsanleitung im Effektmodul selbst.

[Kompressor] macht laute Stellen leiser, leise Stellen bleiben wie sie sind.

[Normalisieren] entfernt eventuell vorhandene Gleichspannungsanteile (billiger Soundkarten) und gleicht die Lautstärke unterschiedlich lauter Tondateien an.

[Verstärken] Beim Aufrufen dieser Funktion wird das rechte Popupfenster geöffnet. Wobei Audacity im Bereich "Verstärkung (dB)" automatisch die maximal mögliche Verstärkung (dh. ohne Verzerrung) des markierten Bereiches angibt. Dieser kann mit dem Schieberegler oder durch direkte Eingabe verändert werden ( - Werte = leiser / + Werte = lauter ). Wird der vorgeschlagene Wert allerdings überschritten, so kann dieser Effekt nur angewendet werden, wenn man explizit den Bereich "Übersteuerung erlauben" angeklickt wird.

[Vocal Remover (for center-panned vocals)] –ermöglicht unter gewissen Umständen und mit Qualitätseinbußen den Gesang eines Musikstückes zu entfernen [Auto-Duck] Mit diesem Effekt kann man z.b. Musik, die als Begleitung von Gesprochenem dienen soll, an eben diesen gesprochenen Stellen leiser erscheinen lassen.

http://manual.audacityteam.org

Claude Schmit, Februar 2010

[Wiederholen] Mit diesem Effekt kann man den markierten Bereich um die Anzahl, wie in der Zeile "Number of time to repeat" angegeben ist duplizieren. Dadurch wird der nachfolgende Bereich um diesen Faktor zugleich mit verschoben.

[Rückwärts] Spielt die markierte Auswahl rückwärts.

[Vocoder] 'Computerstimme' Effekt [GVerb] Halleffekt.

[Tremolo] Lautstärken-"Vibrations"-Effekt [High Pass Filter] Hochpassfilter (lässt nur Höhen übrig - einstellbar).

[Low Pass Filter] Tiefpassfilter (lässt nur Bässe übrig - einstellbar).

Export To hear your work in other media programs, export it to an audio file such as WAV or MP3 (some formats are unsupported). Saving an Audacity project creates a project file (and linked _data folder) containing all your edited tracks, so you can return to your work later. However, other programs can't read Audacity projects.

To export, click File > Export then choose the file format you want to export to in the "Save as type" dropdown. To burn a CD for standalone CD players, choose WAV or AIFF. To export as MP3, the Lame Encoder must be installed.

File > Export Selection exports only a selected area of audio. Use File > Export Multiple to export multiple files at the same time, either one for each audio track, or one for each labeled area in a single track. Tracks > Add Label At Selection lets you split the tracks from an album for multiple export as separate files.

BurnCD To burn your work to an audio CD for standalone CD players, first export it as WAV or AIFF. The exported file should be stereo, 44100 Hz (set in the "Project Rate" tool at the bottom left of the project window) and 16 bit (set via the "Options" button in the file export dialog). These are Audacity's default settings, so normally you will not need to change these before exporting.

Burn the exported file to an "audio CD" - not a "data CD" with a CD burning program like iTunes or Windows Media Player.
