Answer: Inspect channel content and the recipient’s required routing. Two channels can contain a stereo scene, two independent microphones or one useful signal plus silence.

Why the distinction matters
Channel count alone does not identify the creative or technical relationship between channels. A camera can record separate microphones left and right, and an editor can interpret them in ways that affect playback. Keep the source intact and inspect each channel through the application’s supported controls. Avoid summing without listening because phase and level relationships can change the result.
A practical sequence
- Identify the source channel layout and listen to each channel separately.
- Determine whether the channels are a stereo pair, independent dialogue sources or another layout.
- Route and process them according to the actual delivery brief.
- Export a proof and check ordinary playback as well as individual-channel content.
Decision record
| Check | What it means | What to verify |
|---|---|---|
| Stereo pair | Related left/right scene | Preserve intended image |
| Dual mono | Independent microphones | Route deliberately |
| One silent channel | Incomplete or intentional layout | Resolve against brief |
Worked example
A hypothetical interview has the presenter on the left channel and the guest on the right. Treating the file as a finished stereo mix can put each voice on only one side. The useful correction is an intentional dialogue routing and mix, followed by a level check, rather than a blind loudness gain.
Verify the result
Record the final layout in the delivery manifest. Check that a downmix or mono playback does not lose important content. Channel corrections and loudness compliance are separate verification steps.

Question and answer
Does a two-channel export prove stereo sound? It proves two channels were written. Inspect what they contain and how they are intended to relate.
