学习目标LEARNING OBJECTIVES

学完你能看懂片段的声道格式（mono / stereo / adaptive），并把它改成时间线里能分轨使用的配置。

概念说明CONCEPTS

音频通道配置（Audio Channel Configuration）决定片段的多个声道以几条轨进入时间线——同一段录音，配置不同，拖进时间线的样子完全不同。

  • stereo 是一条轨：2 ch - stereo 把左右声道捆成一条立体声轨，时间线上只占一条音轨。
  • adaptive 也是一条轨：多麦克风录音常默认 4 ch - adaptive，四个声道都在，进时间线却仍是一条轨。
  • mono 每声道一条轨：改成 4 ch - mono 后，Mix、Boom、领夹麦等各声道独立成轨，可分别取用。
  • 改配置要趁早：通道配置的改动不影响已经用在时间线里的片段，入线之前配好最省事。

操作步骤STEPS

  1. 在媒体池选中要配置的音频片段，可多选批量改
  2. 打开 Inspector，切到 File 选项卡，找到 Audio Configuration 面板Inspector 里的 Audio Configuration 面板
  3. 在 Format 下拉菜单选 4 ch - mono，让每个声道独立成轨Format 下拉菜单选择 mono
  4. 逐条波形点放试听，确认每个声道录的是什么
  5. 需要 5.1 等复杂组合时，Format 选 Custom，在 Clip Attributes 窗口细调Clip Attributes 窗口的声道设置

练习PRACTICE

  1. 找一段双声道素材，在 stereo 与 mono 配置间切换，各拖一次进时间线，对比轨数差别。
  2. 把一段四声道录音改成 mono，在 Audio Configuration 面板只勾选领夹麦那一路，试听结果。

常见问题FAQ

为什么我的四声道录音进时间线只有一条轨？

它多半是 adaptive 配置——声道都在，只是捆成了一条轨。回媒体池把 Format 改成 4 ch - mono，再拖进时间线就是四条轨。

改完配置，时间线里已有的片段怎么没变？

通道配置只影响之后进时间线的片段。已入线的片段保持原样，删掉重新拖入即可套用新配置。

stereo 和 mono 到底选哪个？

音乐、环境声本来就是左右声道，保持 stereo；采访等多麦克风录音选 mono，才能按麦克风分轨取用。

Learning Objectives学习目标

After this card you can read a clip's channel format (mono / stereo / adaptive) and reconfigure it so the channels land as separate tracks in the timeline.

Concepts概念说明

Audio Channel Configuration decides how many timeline tracks a clip's channels arrive on — same recording, different configuration, completely different result once edited in.

  • Stereo is one track: 2 ch - stereo bundles left and right into a single stereo track.
  • Adaptive is also one track: multi-mic recordings often default to 4 ch - adaptive — all four channels exist, but they still land as one track.
  • Mono is one track per channel: switch to 4 ch - mono and each channel — mix, boom, lav mic — becomes its own track you can use independently.
  • Configure early: channel changes don't affect clips already used in any timeline, so set the format before editing.

Steps操作步骤

  1. Select the audio clips in the Media Pool — multi-select to batch-configure
  2. Open the Inspector, switch to the File tab, and find the Audio Configuration panelThe Audio Configuration panel in the Inspector
  3. In the Format dropdown choose 4 ch - mono so each channel gets its own trackChoosing mono in the Format dropdown
  4. Scrub each waveform to hear what every channel recorded
  5. For complex layouts like 5.1, choose Custom in Format and fine-tune in the Clip Attributes windowChannel settings in the Clip Attributes window

Practice练习

  1. Take a two-channel clip, switch it between stereo and mono, and edit it into a timeline each time to compare the track count.
  2. Reconfigure a four-channel recording as mono, enable only the lav-mic channel in the Audio Configuration panel, and listen to the result.

FAQ常见问题

Why does my four-channel recording land on the timeline as one track?

It's almost certainly set to adaptive — the channels exist but are bundled together. Back in the Media Pool, change Format to 4 ch - mono, then edit it in again for four tracks.

I changed the configuration — why didn't the clip already in my timeline change?

Configuration only affects clips edited in afterwards. Clips already in the timeline keep the old layout; delete and re-edit them to apply the new one.

Stereo or mono — which do I pick?

Keep stereo for music and ambience recorded as left/right; choose mono for multi-mic interviews so each mic gets its own track.
