Which panel is used to adjust audio effects applied to a clip in Premiere Pro?

The Audio Track Mixer is specifically designed for adjusting audio levels and effects applied to audio tracks in your project. It provides a comprehensive interface that allows you to control volume, panning, and effects for each audio track individually or as a whole. This mixer is essential for mixing multiple audio tracks together and gives you the capability to work with effects in a real-time, intuitive manner.

While the Effects Panel is where you can browse and apply various audio effects, it does not offer the real-time adjustment capabilities that the Audio Track Mixer provides. The Audio Clip Mixer serves a similar purpose but is focused on individual clips rather than tracks. The Effect Controls panel displays the properties of selected effects applied to clips, allowing for keyframe adjustments, but is not primarily intended for mixing audio across multiple tracks. Therefore, for adjusting audio effects specifically, the Audio Track Mixer is the correct tool to use in Adobe Premiere Pro.
