Just to clarify, Dolby Atmos is not a codec—it’s an audio technology that enables object‑based audio, allowing sounds to be placed and moved in three‑dimensional space. It can be delivered through various codecs, such as Dolby Digital Plus, depending on the platform.
Would you be able to provide more context so that I can better assist with your question?
Best,

So what should I think of the audio format of the atmos sound source from the developer's point of view?
Dolby Digital Plus
- Type: Audio codec
- What it does: Encodes compressed multichannel audio (e.g., 5.1, 7.1)
- Use case: Streaming, broadcast, OTT delivery
Dolby Atmos
- Type: Object-based audio format (not a codec)
- What it does: Adds spatial audio metadata (objects + positioning) on top of a base audio stream
- Key idea: Atmos = audio + metadata, not a standalone encoding format
DDP = how audio is compressed
Atmos = how audio is spatially described and rendered
