Recording

Preparing Audacity for Recording

Before you start recording you will need to perform some checks and tests to ensure your recording is successful.

Device Toolbar

Finally, it is recommended that you test your microphone before you begin recording and adjust the microphone level for optimum quality. To do this, go to the Recording Meter toolbar, click the ‘Click to Start Monitoring’ button, speak at a comfortable level and increase or decrease the Microphone Volume slider, and/or sit closer or further away from your microphone so that it registers peaks around -12dB.

Start Recording

To start recording you will need to use the Transport Toolbar and follow the instructions below:

  1. Click on the red Record button (or keyboard shortcut R) to start the recording.

  2. Say what you wish to say.

  3. Press the Pause Button if you wish to pause your recording at any point, then press it again to resume recording.

  4. Press the Stop button (or press the spacebar) when you have finished recording.

When you have finished recording, you should see your voice represented as an audio ‘waveform’, as shown on the screenshot below.

Single-track Recording using a single microphone ‘1 (Mono) Recording Channel’

If you recorded using a single microphone, your recording will look like the screenshot below

Multi-track Recording using two microphones ‘2 (Stereo) Recording Channel’

If you recorded using two microphones at once, your recording will look like the screenshot below

Listening to Your Recording

You might certainly want to listen back to your recording to check your performance and the quality of your recording. If you are happy with your recording, you can proceed to the next step and save/export your recording, but if you are not happy, you may wish to re-record it again and consult the previous section 'Preparing Audacity for recording'.

Here are the steps on how to listen to your recording:

  1. Click on the Play button in the Transport Toolbar as shown below.

  2. Click on the Stop or Pause button in the Transport Toolbar to stop
    or pause the playback.

  3. You can adjust the volume using the Playback Volume slider in the Mixer Toolbar.

Saving Your Project

Once you have finished recording and you are happy or partially happy with your recording and wish to make some edits, it is important to save the project first to avoid losing any work in case a problem arises. It is also advisable to save your project on a regular basis while editing your audio. Saving your project allows you to revisit your project and continue editing.

  1. Click ‘File’ from the ‘Menu Bar’ > Save Project > Save Project > Ok

  2. Select a drive/location to save your project in

  3. Give your project an appropriate name

  4. Click ‘Save’

Exporting Your Audio File

Once you are pleased with your recording and edit, and are ready to share/upload your audio file to your podcast host, you will need to export your audio file as an MP3 or WAV file.

WAV files are lossless, uncompressed, broadcast CD quality files. Some podcast hosts support WAV formats such as Soundcloud. The drawback with WAV format is that the file size is almost 10 times bigger than an equivalent MP3 file of the same length.

MP3 files are compressed and 10 times smaller than WAV files. They are very useful for Internet
distribution and still play with very good sound quality. If you are looking to upload your podcasts to Moodle, then MP3 is the recommended format.

  1. Click ‘File’ from the ‘Menu Bar’ > Export > Export as WAV/MP3

  2. Select a drive/location to save your file in

  3. Give your audio file an appropriate name

  4. If you have chosen to export as WAV, click ‘Save’ and go to step 5. If you have chosen to export as MP3, you will see a bunch of options (Bit Rate Mode, Quality and Variable Speed) which can be left as preset except for Channel Mode as you need to choose ‘Stereo’ if you have recorded using two microphones and the left and right are different, otherwise choose ‘Force export to mono’ if you have recorded using a single microphone and this is would be the case for most podcasts.

  5. You will be prompted to complete a metadata form, but this is optional and isn’t necessary so you can just click on ‘Ok’.

Editing

Having completed your recording, you might wish to edit your recording either by deleting unwanted sections of your recording, record additional material, and/or adding an intro/outro music. Audacity provides a wide range of editing functions, which are briefly introduced here.

Basic Editing

Deleting Audio

There might be reasons why you wish to delete a section of your recording. For example, perhaps you made a mistake in the middle of your recording and wish to delete that portion or delete some silence at the beginning or end of your recording.

To delete a section of your recording:

  1. Open your project/WAV file that you wish to edit by going to the Menu Bar > File > Open > double click on your file

  2. Click on the Selection Tool in the Tools Toolbar

  3. Go to the Waveform of your audio track

  4. Click and drag the part of the audio waveform you wish to delete in the audio track

  5. The selected portion should be highlighted. It is recommended that you first click the Play button in the Transport Toolbar and listen to the highlighted portion to ensure that you are deleting the right portion of your recording

  6. You can press the Delete key on your keyboard to delete it or go to the Menu Bar > Edit > Delete

  7. The unwanted audio is now removed, and the audio either side of the selected region is joined together leaving no gap.

  8. Save your project or export it as WAV/MP3 file

Tips: You can use the Zoom tool to make it easier to select the portion of the recording that you wish to delete. If you made a mistake and deleted a wrong section, you can undo it by clicking Ctrl+Z on your keyboard or by going to the Menu Bar and click Edit > Undo.

Advanced Editing

Adding a New Piece of Recording to an Existing Recording

There may be several reasons why you wish to add a new piece of recording in the middle of your original recording. For instance, you have forgotten to mention something and wish to add it, or you made a mistake and wanted to replace that part.

To add a new piece of recording to an existing recording:

  1. Open your project/WAV file that you wish to edit by going to the Menu Bar > File > Open > double click on your file

  2. Click on the Selection Tool in the Tools Toolbar

  3. Go to the Waveform of your audio track and click on the point from where you wish to add the new piece of recording

  4. Go to the Menu Bar > Tracks > Add New > Mono Track. You should now have a new audio track created.

  5. Go to the Transport Toolbar and click on the Record button to start recording your new piece of audio and when you have finished, click on the Stop button

  6. Now the two tracks overlap and if you press the Play button, your two recordings mix together in the middle. To resolve this issue, you will need to move the second half of your original recording to a new audio track.

  7. Create a new audio track for the second half of the original recording by going to the Menu Bar > Tracks > Add New > Mono Track. You should now have a new audio track

  8. Go to the original audio track and use the Selection Tool, and highlight the waveform from the point the second track starts to the end

  9. Go to the Menu Bar > Edit > Clip Boundaries > Split (alternatively, press Ctrl+I on your keyboard). This will split the highlighted section from the original track.

  10. Go to the Tools Toolbar and click on the Time Shift Tool, then click and drag the highlighted waveform to the new audio track so it lines up with the end of the waveform on the above track

  11. Now if you playback the recording from the start, it will play as a one piece of recording without any overlapping

  12. Save your project or export it as WAV/MP3 file

Adding Intro/Outro Music

You may wish to enhance your podcast by adding an intro/outro music to your recording. You can approach this in different ways. When importing your desired music, it is advisable to adjust the volume so that all the audio tracks are at the same level. You can use effects such as Fade In and Fade Out or manually adjust the fade by using the Envelope tool.

Copyright: When importing music into your podcast, ensure that you obtain them from royalty-free music sites to avoid copyright issues. For example, Bensound and Mixkit. Further information on copyright can be found here.

To add an intro/outro music to your recording:

  1. Open your project/WAV file that you wish to add an intro/outro music to by going to the Menu Bar > File > Open > double click on your file

  2. Import your intro/outro music by going to the Menu Bar > File > Import > Audio… > find your music and double click on your file. (Audacity allows you to import audio in WAV and MP3 formats.) Audacity will add it as a new track below your recorded audio. The music file you have imported is likely in stereo, so it looks different from the track you have recorded with the microphone having two waveforms, one for stereo right and the other for stereo left.

  3. After importing your music file, you may find the volume needs to be adjusted to match your recording. To do this, go to the Track Control Panel and click and drag the volume slider.

  4. Now you need to move the original track that you have recorded to the right, by 5,10 or 15 seconds, completely up to you how long you want the intro to last for so that you allow the intro music to be heard without overlapping with your recording. To do this, you need to use the Selection Tool in the Tools Toolbar and highlight your entire waveform recording and then click on the Time Shift Tool and click on the highlighted waveform and move it to the right depending by how many seconds you would like the intro to last.

  5. You may wish to create a gradual fade in at the beginning of your audio track to create smooth transitions between your audio clips to make a seamless listening experience for your audience. To do this, use the Selection Tool and highlight the intro music track from the beginning until your original audio track starts, and then go to the Menu Bar > Effect > Fade In.

  6. Now when you playback, you will notice that after the intro, your audio recording starts but the background music is too loud and you may wish to adjust the volume manually to fade away to nothing. The Envelop Tool gives you more flexibility and allows you to manually fade in and out. To do this, go to the Tools Toolbar and click on the Envelop Tool, you will notice grey bars appear at the top and bottom of each clip, bordered at the edges by a purple line. Click on the waveform of the background audio, this will create a control point. You may wish to create multiple control points to give you more flexibility when adjusting the volume. Now click and drag up or down the control points to adjust the volume.

  7. For your outro, you may wish to create a gradual fade out at the end of your audio track similar to the intro in step 6. Use the Selection Tool and highlight the portion for your outro music, go the Menu Bar > Effect > Fade Out.

  8. If the music track you have imported is too long and you wish to delete the end of it, use the Selection Tool and go to the waveform and highlight the portion you wish to delete. Then press the Delete key on your keyboard to delete it or go to the Menu Bar > Edit > Delete.

  9. At this point, if you are happy with your editing, save your project or export it as WAV/MP3 file.
