The "Subscribe to Cryo Mix" voice in your playback is the preview watermark. Any paid plan removes it.
While you're working on a project, playback includes an audio watermark, a short spoken tag such as "subscribe to Cryo Mix" or "mixed by Cryo Mix" layered into the sound. If you're hearing a voice between or over your music, that's what it is, not a glitch in your track.
It protects work made during the free preview stage, before a subscription is active. It's only applied to previews.
Any paid subscription removes the watermark. Once you subscribe, Cryo Mix detects your active plan and lets you reprocess your tracks to produce a clean version without the audio tag.
Not currently. Previews always include the watermark until you have an active subscription. There's no watermark-free preview on the free plan.
