* **Bitrate**\
  Applies to **AAC** and **AC3** audio exports; determines the output audio bitrate.
* **Sample Rate**\
  Sets the output sample rate for the exported audio.
* **Resample Quality**\
  When the sample rate differs from the source (e.g., converting from 44.1kHz to 48kHz), this option controls the **quality of the resampling** process.

#### **Channel Settings**

* **Channel Mapping**\

  You can map audio based on:\
  ▸ **Audio Channel #**\
  ▸ **Speaker Output #**
* **Channel Layout**\
  Defines how the audio channels are structured in the exported file:\
  ▸ **Auto** – Matches the layout of the source file\
  ▸ **Discrete** – Each channel is saved in a separate audio track\
  ▸ **Interleaved Pairs** – Pairs of channels are grouped into single tracks\
  ▸ **Single Track** – All channels are combined into one audio track
* **# Channels**\
  Sets the number of channels to include in the export file.
