Converting Stereo to Multi Channel

Thank you for the Lexicon information but, I was talking about the VST:

OrilRiver VST plugin review: Reddit community's perspective

Based on discussions and feedback on Reddit, OrilRiver is a highly regarded free reverb VST plugin among music producers and audio engineers.

Here's a summary:

• Excellent Sound Quality (especially for a free plugin): Many users praise its sound, often comparing it favorably to commercial options. It's described as capable of producing natural-sounding ambiance for various instruments and vocals, as well as lush and expansive soundscapes.
• Intuitive and User-Friendly: Its layout and controls are generally considered easy to understand and use, making it suitable even for less experienced users.
  • Separate sliders for Dry, Early Reflections (ER), Reverb, and Wet signals.
  • 12 ER presets and 5 reverb tail variations.
  • Basic controls like pre-delay, width, and decay time.
  • Additional parameters such as room size, diffusion, damping (intensity and cutoff), and modulation (speed and depth).
  • A three-band EQ for fine-tuning the reverb's tonal characteristics.

The plugin also has a wide number of presets for two channel I haven't tried, taken a recording processed with OriRiver and then running in through 5.1 or 7.1 multichannel yet.

However, from just fooling around with the plugin, I have gotten some amazing results from two channel.

I understand that. I was pointing out that the plugin doesn't do any sort of ambiance extraction or surround sound. It is generating reverb and adding it to the music, not using what is already within the recording. Your quote above confirms that. I referenced the Lexicon file as it explains the difference between ambiance generation and ambiance extraction. If you are trying to take a stereo source and play it back in surround sound you need ambiance extraction, also called surround processing and lately called upmixing.

Example of a 2 channel stereo mix (meters on left) being surround processed into 18 channels (meters on right) with nothing at all being added that isn't already in the recording.

Dolby offers tools for mixing and encoding Dolby Digital, TrueHD, Atmos and Auro offers simlar tools for the last one.
There is also Illusonic plug-ins

Looks good. When do you think it will be available ?

I suspect Atmos by brute force.

Agreed

Impressive plugin !

But, if OriRiver doesn't have "ambiance extraction" why would the plugin have a couple presets labeled "Ambiance" I'm not an expert just asking since the plugin did get great reviews wouldn't the critics point out the inaccuracy of the preset?

I am using hardware, not a plug in.

Again, that plugin is generating ambiance/reverb. The presets alter the generated hall size of the reverb/ambiance. The key words in your quote is “producing natural sounding ambience.” Producing means creating it.

Read the whole Theory and Design booklet I linked to earlier. It explains the difference well since I am failing to be able to.

You are correct, it doesn't extract ambiance.

Yes, OrilRiver is designed to create and simulate ambience, not extract it from an existing track.

Here's why:

• OrilRiver is an algorithmic stereo reverb plugin.
• It functions by simulating the reverberations of different spaces (rooms, halls, etc.) and applying them to the audio signal passing through the plugin.
• It offers various parameters to craft the desired ambience, such as room size, decay time, diffusion, and early reflection controls.
• It can create very natural and realistic ambient spaces, making instruments and vocals sound like they are in a specific acoustic environment.

Essentially, you apply OrilRiver to a track to add the desired ambience, rather than removing it. If you were looking to remove or reduce existing ambience from a recording, you would need a different type of plugin or process, such as a "de-reverb" tool.

I guess it would be the next best thing for those of us that don't have Lexicon.

Still in the testing stage...could be awhile.

There we go. Its purpose is to take a dry recording (or just dry tracks) and to add reverb/ambiance to it. It isn't doing anything surround related as it isn't multi-channel.

If you are truly trying to go from stereo to surround, this isn't what you need. You need surround processing. It doesn't have to be a Lexicon, though they are very very good at this for music. Anything with DPLII will do a good job too. Other upmixers/surrround processors tend to not be as competnent on music.

Interesting discussion… there is the below that is using Auro3D … if it takes off, maybe Atmos won’t be the only game in town for immersive music processing …

Just wondering which format will emerge as the winner offered to the market as the next "Must have so update your music collection today"

Maybe its just me, I don't find Atmos all that compelling myself, don't have any desire to mount speakers in my ceilings....and most Atmos mixes are algorithm generated anyways.
