# AudioChannelLayout（ロブロックス 列挙型（Enum）） > Describes the channel layout of an audio stream. - URL：https://roblox.minecraft-okinawa.com/reference/enums/AudioChannelLayout/ - 公式：https://create.roblox.com/docs/reference/engine/enums/AudioChannelLayout ## 選べる値 - Enum.AudioChannelLayout.Mono（0）：Monaural audio streams contain only one **Center** channel. Diagram showing position of channels for Mono layout. - Enum.AudioChannelLayout.Stereo（1）：Stereophonic audio streams consist of two channels: **Left** and **Right**. Diagram showing position of channels for Stereo layout. - Enum.AudioChannelLayout.Quad（2）：Quadrophonic audio streams consist of four channels: **Left**, **Right**, **BackLeft**, and **BackRight**. Quadrophonic streams can encode forward/backward spatial information that stereo streams might struggle with. Diagram showing position of channels for Quad layout. - Enum.AudioChannelLayout.Surround_5（3）：Surround sound audio streams consist of five channels: **Left**, **Right**, **Center**, **BackLeft**, and **BackRight**. Surround sound streams encode spatial information with better resolution front and center. Diagram showing position of channels for Surround 5 layout. - Enum.AudioChannelLayout.Surround_5_1（4）：5.1 surround sound consists of six channels: **Left**, **Right**, **Center**, **BackLeft**, **BackRight**, and a **Sub** (subsonic) low‑frequency channel. 5.1 surround sound benefits from low frequencies being less directional in order to encode higher resolution spatial information versus simple 5‑channel surround sound.
