| Display Text | Mono Audio |
| Description | "Mono Audio" refers to the duplication of an audio track, eliminating any stereo or surround spatial separation/panning. |
| Impact | Any missing spatial separation and/or panning effect gives the member an incomplete and incorrect experience. It will not fully reflect the creatively intended mix aligned with on-screen action. |
| Severity Assessment Guidance | |
| FYI | N/A |
| Issue | Audio mix does not contain any stereo or surround panning between channels. Levels are identical across multiple/all channels through a scene/program where contextual cues would clearly indicate there should be at least some fluctuation. Mono audio is also clearly visible on a phase scope, where the audio signal exhibits zero phasing or panning between stereo pairs. |

| Solutions | |
| How to Prevent |
Label tracks correctly in metadata. Be sure to do a proper mixdown whenever combining channels (versus simply duplicating tracks). Verify bussing when exporting. |
| How to Fix | Replace mix to ensure spatial separation and panning are maintained, and redeliver. |
