In Adobe Premiere Pro, you can edit audio, add effects to it, and mix as many tracks of audio in a sequence as your computer system can handle.
There are various types of tracks in Premiere Pro. We will use Standard tracks for this project.
Before importing audio
You can import digital audio clips stored as audio files or tracks in video files.
Using compressed audio formats
Music stored in formats such as MP3 and WMA are compressed using a method that removes some of the original audio quality. To play back compressed audio, Premiere Pro must decompress the file and may need to resample it to match your output settings. Although Premiere Pro uses a high-quality resampler for this purpose, the best results come from using an uncompressed or CD audio version of the audio clip whenever possible (AIFF or WAV files).
Please note that some of the material you find on line or from other sources may have a sample rate such as 44.1 kHz.
Editing your audio project
1. Open Premiere Pro and create a new project
2. Create a new sequence File>New>Sequence
3. In your settings look at Tracks and set your Master Audio to Stereo and your tracks to Standard, see picture below. For this project please don’t use more than 3 tracks of audio.
4. Now import your audio files: File>Import> select the folder where your files are stored and click Import.
5. Double click on your folder to see your files and double click on your files to listen to them.
6. You can adjust the volume by clicking on >Effects Control on top of your viewer (top left) Volume>Level.
7. Listen to your track and give Inpoints (I) and Outpoints (O) when you hear a good sound bite that you might want to use and bring it into your timeline just like we did with video.
Make sure you can properly see the audio waveforms:
Hover over the track selector, scroll up with the mouse wheel, and adjust the height of the track.
Monitor the audio levels. Do not rely on your hearing to measure the audio levels. Use the audio meter to help to measure:
Interviewee’s voice: should peak between -24dB and -12dB. Between -12dB and -6dB is okay.
Other sounds: louder sounds can peak between -6dB and 0dB, and quieter sounds can peak between -30db and -24db.
NOTHING can ever get above 0db.
Adjust the audio level:
To lower the audio level of a clip: click and drag the yellow line downward.
To higher the audio level of a clip: click and drag the yellow line upward.
*If you don’t see the yellow line: click the “volume menu” at the top of the clip (fx), then select “Volume” and “Level”.
Adjust the audio gain - only if it’s really necessarily!
If you have higher the audio level (see point 3) but the voice still not loud enough, you have to adjust the audio gain: right click on the clip and select “Audio Gain”.
The “Audio Gain box” automatically opens. Select the option “Adjust Gain by” and set the dB gain value until the voice peaks properly.
Track Targeting & Source Patching
Now let’s try and understand how our timeline “thinks” !
There is an area responsible for Source Patching and it only becomes available when something is selected in your source viewer and when selected it does exactly what it says, which is patch the source to where it goes on the timeline when doing an Overwrite (.) or Insert (,) edit.
Source Patching Area:
Let’s say you want to add music into your timeline, which you can import in your Project Panel the same way you imported your interview files. You want your music track to go below your interview track.
I’m going to select my source patch on my second track (A2) and do an overwrite edit - see pic below:
*Source Patching is not the same as Track Targeting. In a way Source Patching is how your timeline communicates with your viewer. Track Targeting is the way the timeline talks with its tracks.
Targeting Tracks (area to the right of the lock) - allows you to decide which track you want your files to go into and also what tracks you’re targeting at any given time. This tool is particularly useful if you’re copying and pasting sound bites and you want to avoid overwriting onto other tracks.
All you have to do to target a track is to select the track with the toggle tool on the controls at the left of your timeline viewer, see picture below, and then copy and paste.
See how the second track is selected and the other tracks are not so that when I copy and paste my music track or effects it will not overwrite on my interview.
If your clip is still not pasting where you want it I suggest you double check where your timeline indicator is (the blue triangular indicator) - the clips will paste where the indicator is positioned in your timeline.
Audio Transitions
Audio transitions are similar to Video transitions already explored for the first assignment.
Fade in or fade out clip audio
Make sure that the audio track is expanded in a Timeline panel. If necessary, click the triangle to the left of the track name to expand the audio tracks that you want to crossfade.
Do any of the following:
1. To fade in a clip’s audio, drag an audio transition from the Effects panel to a Timeline panel so that it snaps to the In point of the audio clip. You can also select the applied transition in a Timeline panel. Then, in the Effect Controls panel choose “Start At Cut” from the Alignment menu.
2. To fade out a clip’s audio, drag an audio transition from the Effects panel to a Timeline panel so that it snaps to the Out point of the audio clip. You can also select the applied transition in a Timeline. Then, in the Effect Controls panel, choose End At Cut from the Alignment menu.
Use any of the three types of audio crossfade transitions to fade in or fade out.
Adjust or customize an audio transition
Do any of the following:
1.To edit an audio transition, double-click the transition in a Timeline panel and adjust the transition in the Effect Controls panel.
2. To customize the rate of an audio fade or crossfade, adjust the clip’s audio volume keyframe graph instead of applying a transition. In order to do that you must first expand the audio track with the bar on the bottom left side of timeline. Then select the Pen Tool and give your track a keyframe (a marker) at the beginning and then another one after a few seconds. If you drag the second keyframe up with your pen tool, the volume will go up. See picture below:
Export
Once you’re ready to export, give your timeline an Inpoint (I) and Outpoint (O) and then select File>Export>Media
In your export window deselect video.
Format: Quicktime. Look at your Audio settings:
Codec: AAC
Sample Rate: 48000Hz
Single Track
Bitrate: 320
When you’re finish exporting you can listen to your track and if you like it you can go ahead and upload!
