What is the purpose of the Audio Mixer in Avid Media Composer?

The Audio Mixer in Avid Media Composer serves a crucial function in the audio editing process. Its primary purpose is to adjust audio levels, ensuring that sound is balanced and clear across different tracks. By controlling the volume, panning, and effects of audio clips, the Audio Mixer allows editors to enhance the auditory experience of their projects. This tool is essential for fine-tuning the sound elements, adding effects like reverb or equalization, and managing the dynamics of the audio mix, ensuring that dialogue, music, and sound effects all have the appropriate presence in the final output.
