Cryo Mix V2's Nova shows its working. That should be the bar for AI mixing

Cryo Mix announced V2 on 9 January 2026 and describes it as an engine rebuilt from the ground up. Three changes matter if you mix your own music: a conversational assistant called Nova, uploads of up to 32 stems (the old limit was eight lead and eight backing vocals), and an analysis panel next to every stem that reports what the AI did to it. That last one is the reason to pay attention.

What does Nova actually do?

You type a request in plain language and Nova turns it into processing. Cryo's launch post gives examples like punchier drums or more air on a vocal, and says Nova suggests changes that you approve or decline. Advanced Mode, where you set every stem's parameters by hand, is still there.

The Nova help page adds detail. Nova remembers the conversation, so you can ask for louder vocals, then "a little bit more", then pull back if it went too far. You can target the whole mix, a single stem, or a stem by its file name. Cryo says Nova is tuned for vocal production and understands words like "airy", "boxy" and "muddy", and that it adjusts EQ, compression and effects behind the scenes.

Those changes land somewhere you can see. The mixing help page says Nova adjusts the Advanced Settings, a dashboard of controls that includes compressor, EQ, reverb/delay and saturation, and that you can A/B the raw, mixed and mastered versions. Nova also works in mastering, where Cryo says you can ask for a wider, louder or more dynamic master.

Why does the processing report matter?

Cryo pitches the report as the end of the "black box", where audio goes in, audio comes out and you never learn what happened in between. According to the launch post, the panel beside each stem can show how much EQ correction was applied, where compression was added and which tonal shaping moves were made. Cryo says it wants the tool to be educational. One caveat sits in Cryo's own wording: the report covers what the AI did "based on the advanced settings that are enabled", so it's not clear that it describes everything.

This matters because a mix is a set of choices. If a tool only returns a finished file, the only thing you can do is accept it or reject it. If it tells you it cut the low mids on the vocal and compressed the hook harder, you can disagree with one move, undo it and keep the rest. You also learn something you can use next time without the tool.

Independent research points the same way. A 2023 study of AI in mixing workflows combined interviews, a questionnaire and forum analysis. It found that AI mixing tools can give amateurs decent results with less effort, while "pro-am" users wanted precise control and customisation, and professionals wanted that plus assistive, collaborative tools. Nova's design, with suggestions you approve and settings you can see, is aimed at that middle group.

A word on evidence. We haven't tested V2 ourselves. Cryo's pages don't say how fine-grained the report is beyond those examples, or whether you can export it. We looked for independent user reviews and found very little we could verify; a Reddit thread comparing AI mixing tools was blocked from our side. Everything here about how Nova behaves comes from Cryo.

What happens to your stems and your prompts?

This is where artists should read the small print. Cryo's terms of service, last updated 27 September 2026, split what you upload into two buckets.

• Your music ("Music Content"): you give Cryo a non-exclusive, royalty-free licence that lasts as long as you host the music on the service and only to the extent needed to provide the service. The terms also say the providers of the AI models Cryo uses may train on Services Data "not including Your Music Content".
• Everything else ("Services Data"): defined as mastering settings, audio classifiers, metadata, keywords, presets, prompt inputs and similar data. Cryo says it may use this for any purpose, including AI training and licensing to third parties, under a perpetual, irrevocable licence.

The terms don't set a retention period for uploads, and they say you are responsible for keeping your own backups. The privacy policy, updated 6 October 2026, says Cryo's AI assistants, Nova included, receive your messages plus session details such as track names, instrument categories, plugin settings and audio measurements. It says AI model providers process this as Cryo's service providers and that the data is used partly to improve the assistants. It doesn't say how long uploaded audio is kept. The site footer has a "Model Card" link, but we couldn't read its contents.

Cryo also replaced its unlimited plan with credits at launch: one credit unlocks a project, unused credits roll over, and former unlimited users got 999 credits, according to the launch post.

Where does this sit among AI mix tools?

The useful split in AI mixing isn't between brands. It's between conversational, auditable assistants and one-click services that hand back a file. Cryo is now firmly on the first side. Others are taking the same route, such as Veena, whose AI co-producer builds and mixes a track with you layer by layer.

What we think

Explainable mixing should be the bar every AI engineer is held to: show the chain, show the moves, and let the artist overrule any of them. Cryo deserves credit for making that the headline of V2 rather than a hidden setting.

Here's what's less obvious. The feature that makes Nova honest is also what makes it valuable to Cryo. Every time you type "more air on the vocal" and accept or reject the result, you create a labelled pair: a plain-language intention and the exact settings that met it. Under Cryo's terms, those prompts and settings are Services Data that it can keep forever, train on and license to others. Your audio is fenced off. Your judgement isn't. Cryo doesn't say whether it trains on them, but the terms allow it. Over thousands of sessions, that would mean artists teaching the engineer for free, with the asset that builds up belonging to the tool, not to the people whose taste trained it.

That isn't a reason to avoid the tool. Bedroom producers without an engineer get real value from a mix they can read and learn from. It is a reason to ask for three things that would make "explainable" mean what it should:

1. An opt-out from training on your prompts and settings, separate from the audio protections that already exist.
2. A stated retention period for uploaded stems, and deletion on request.
3. An exportable report, a recall sheet you keep, so you could rebuild the mix in your own DAW if you leave.

A tool that explains its moves to you should be just as clear about what it keeps from them.
