Sound Design – Audition Troubleshooting

There are some common problems that appear when working with Audition. Here are some tips on where to look first.

Sounds are not playing, the location bar is stuck, or hearing a constant glitch sound that the sound file doesn’t have.

This can be due to the sample rate setting.

What is sample rate?

In digital audio processing, the original analog sound has to be converted into a digital one in order for computer to process it. This is done by a series of snapshot measurements, samples. Normally it takes thousands of measurements per second. If we can take tons of measurements extremely quickly, we can effectively use these snapshots to reconstruct the original analog wave.

Sample rate is the number of snapshop per second, and is written in Hz. A common sample rate is 44100Hz (44.1 KHz) or 48000Hz (48 KHz). Every audio hardware offers various sample rates so as your laptop. Some laptops have several choices, and some have only one sample rate. When your DAW software’s sample rate is set to a different sample rate from your hardware, then one of those problems can appear.

Then the solution is to change your sample rate into the same one as your audio hardware setup. This can be done in Preferences/Audio Hardware…

When you import your sound files that are sampled with a different sample rate from your audition sample rate setting, you get a message if you’d like to convert the file into the audition’s sample rate setting. then you should click ‘Yes’ to it. Some versions of Audition do this automatically. So if you don’t have any trouble, then it is already made.

What is bit depth?

You have probably seen 44.1KHz 16bit, 44.1KHz 24bit, etc. Those 16bit or 24bit refers to the bit depth.
Think the sample rate is to divide time (the horizontal axis in the graph) into small grids in order to sample a sound. Then bit depth is to divide the amplitude (the vertical axis) into small snapshot to make more accurate conversion. The graph below shows a getting higher number of bit depth and sample rate together.

If the bit depth is higher, then there is less possibility to make an error when sampling a sound. This also means that the sound quality is much closer to the original sound.

How can I check the sample rate of my laptop?

Normally Audition is doing the job for you. However we have seen that this has not been done. Here is a tip

Windows system:

In audition, click ‘settings’ in Preferences/Audio Hardware…

Then you will see the main speaker that you are using. Click Properties, then the Advanced tab, click the drop-down and it will show you the sample rate and bit depths options as shown in the photo below:

Those are all possible sample rate and bit depth for your laptop. Make a choice and set the same sample rate in your Audition.

Max OS:

  1. Click the Launchpad rocket ship icon in the dock of your MacBook, and then click “Utilities” and “Audio Midi Setup.”
  2. Click the name of the output device in the left pane of the Audio Midi Setup window, such as “Built-In Output.”
  3. Click the “Format” drop-down menu, and then click the sample rate you want to use.
  4. Click the drop-down menu located to the right of the “Format” menu, and then click a different configuration, such as “20 bits” or “32 bits.”
