Tutorial: Fixing Muffled Audio with Audio Compression
This video tutorial demonstrates how to restore muffled sections of spoken audio using the Multiband Compressor in Adobe Premiere Pro CC or Adobe Audition.
For Premiere Pro CS6 Users: Using Adobe Audition
As I mentioned previously, the ability to apply the Multiband Compressor effect from within Premiere Pro was introduced in Premiere Pro CC, so if you’re working in Premiere Pro CS6 (or earlier), you’ll need to apply the effect in Adobe Audition. Here's the workflow you’ll use.
To begin, select the audio file and then choose Edit > Edit in Adobe Audition > Clip (to edit a single clip, rather than the entire sequence), as shown in Figure 4 (below), which launches Audition.

As you can see in Figure 5 (below), the waveform looks pretty much the same in Audition as it does in Premiere Pro.

Double-click to select the entire file, choose Effects > Amplitude and Compression > Multiband Compressor (Figure 6, below).
