Independent of the audio compression 'Audio->Audio Encoding Options->Filtering' offers:

• 'Gain' + 'auto': audio volume will be boosted, but only so far to avoid clipping (effectiveness differs depending on the method used)
  
• 'Gain' + 'manual (dB)': audio volume, will be boosted by X dB (effectiveness differs depending on the method used)
  
• 'DRC': apply dynamic range compression to boost just specific frequencies
  
• 'Normalize to (dB)': normalize everything to a specific dB level)
  

best take a clip compress it with different settings and decide which is what you want.
