Channel
声道（音频信号通路）
录音中的单独独立音频数据流。单声道音频有一个通道，立体声有两个（左和右），环绕声系统使用六个或更多通道进行空间音频定位。
技术细节
每个音频声道存储单独的PCM采样波形。标准声道配置包括：单声道（1ch）、立体声（2ch，L+R）、5.1环绕声（6ch：L、R、C、LFE、Ls、Rs）和7.1（8ch）。Ambisonics使用球面谐波进行3D空间音频。声道布局在WAV文件头或AAC/Opus编解码器参数中描述。
示例
``` Audio channel configurations: Mono (1.0) — 1 channel — podcasts, phone calls Stereo (2.0) — 2 channels — music, web audio Surround (5.1) — 6 channels — cinema, gaming Atmos (7.1.4) — 12 channels — immersive audio File size impact: stereo = 2× mono at same bitrate Podcast tip: mono 64 kbps ≈ stereo 128 kbps quality ```
