Week 3 – Guide to Adobe Audition CS6 and recording good audio

How to ensure audio being recorded is of good quality

When recording interviews in public, it is important to get good audio quality. There are a number of steps that can be taken to help ensure the quality of the recorded audio is as good as it can be.

The first thing to consider is the proximity of the recording device to the person speaking, if it is too far away it can be too quiet and if too close the audio can sound muffled.

Another aspect to consider, especially in public, is background noise. This is most commonly wind or other people talking, in order to minimise this in the recording it is a good idea to stand with either, your or the interviewee’s back to the noise. The body helps to block out some of the sound getting to the recording device.

Gain is also something that should be considered, again a good balanced level is important, too high can cause peaking and too low can result in the audio not being audible. In order to check if the audio being recorded is of good quality it is good practise to use headphones so you can hear the quality of the audio being recorded as you record it. This then allows for any changes to be made during the interview rather than having to edit the audio later.

The last thing to consider, while seeming relatively obvious, is battery life and storage capacity on the SD card. If the SD card is full you cannot record any of your audio, and if the battery isn’t charged could run out during a recording.

Adobe Audition Steps

The first step is to add the files to the program.

This is done through clicking File – Import – Highlighting the files and clicking open.

Once the files had been added I clicked the Multitrack button underneath the toolbar. After this it will generate a new multitrack screen, I then clicked Ok to use the default settings.

I then clicked and dragged the files shown on the left and dragged them into tracks.

I then dragged the files into the same track and placed them in a line one after another.

Then I played the track by pressing the space bar and listened to the audio, I noticed it was quiet so clicked and dragged the yellow bar on the audio files up to increase the audio to +15db so it can louder.

After ensuring I could hear the audio I then clipped the silence off the begging and end of the first clip. I did this by moving the red vertical line over to the end of the silence and pressed Ctrl + K to create a cut. I then deleted the silence and moved the files back together so there was no spaced between them.

On the third clip I realised some of the audio was much louder than the rest. I lowered the volume of that section to +6.8db but creating 4 key frames by clicking the yellow line on the clip and lowering two of the frames to the +6.8db level while leaving the first and last key frame I created at the same level creating the dip in audio for that section.

By using key frames it is also possible to create a fade in effect, this is done by creating a key frame at the beginning and lowering it to the bottom of the file.

It is also possible to have audio transition from one to another by dragging one clip into another.

When the file was finished I exported it by clicking File – Export – Multitrack mix down – entire session. I then renamed the file and selected the location. I exported this as a .wav file.
