Yes. The AI audio upmixer returns separate channel stems you can preview and download in Studio. Choose a model, import your stereo file or audio link, then run Multichannel upmix in Stem Split. Front stereo contains the left and right front channels; sides stereo contains the two surround channels; the center stem carries the center channel. The 5.1 model also returns sub frequencies. Jasper and Gillian return 5.0 without a separate low-frequency stem. For an Atmos master, review the spatial routing and export Combined Stems as Atmos (ADM BW64).
