What Halo Upmix does
Because Halo generates a coherent spatial image, the developer notes that the downmix stays of high quality when the surround mix is folded back to stereo.
Halo Upmix is listed for situations that call for an immersive cinematic dynamic, and the developer states that full control is available across the processing.
Key features
- Centre channel management. The centre channel can be shaped separately, and dialog extraction is a switchable mode that pulls speech out of the centre signal.
- Coherent spatial generation. Halo builds its spatial image from the stereo input in a way the developer describes as coherent, which keeps the surround mix consistent when it is folded down.
- Downmix compatibility. The developer states that the downmix from the generated surround stays high quality, so the same session can be checked in stereo.
- Stereo to 5.1 and 7.1 upmix. The plugin converts a stereo source into 5.1 and 7.1 layouts as well as into LCR, 3.1, 4.0, 4.1 and 5.0 layouts.
- Immersive cinematic setting. Halo is aimed at material that calls for an immersive cinematic dynamic, with the developer noting full control over that behavior.
