Key Techniques in Audio Mastering

Several techniques are essential to audio mastering in film. These include:

  • Equalization (EQ): Adjusting frequencies to balance the sound spectrum.
  • Compression: Reducing the dynamic range to ensure consistent sound levels.
  • Limiting: Preventing audio distortion by controlling peak levels.

These techniques require a delicate balance to maintain the integrity of the original sound while enhancing its quality. Mastering engineers often use specialized software and hardware to achieve these effects.
