Selekt Audio Restoration vs Zynaptiq UNVEIL

Selekt Audio Restoration is a browser-based tool for cleaning vocal recordings and older recordings or transfers. Modern voice mode targets steady room noise in isolated vocals, voiceovers and podcasts; vintage mode addresses hiss, hum, crackle, clicks and surface noise. Users can optionally master the cleaned track at no charge and compare or download the original, restored and mastered versions. The tool accepts MP3, WAV, FLAC, M4A and OGG files up to 250 MB. Modern voice mode treats non-voice audio as noise, so a full mix may require separating the vocal stem first. Users can also choose stems to split restored audio. Uploads are processed privately and are not added to the catalog. Results appear in My Library → Studio Results and remain available to stream or download for 48 hours. The restoration workflow is part of Selekt’s connected audio workspace, where results can move to tools such as Stem Lab and Drum Kit. A free plan is available; paid access starts at $5 per month, with an annual option at $50 per year.

Zynaptiq UNVEIL is a real-time de-mixing plug-in for adjusting reverb and other less perceptually important components in mixed audio. It can reduce or increase reverb, change its characteristics, and turn down components described as mud to bring recording details forward; those components can also be added back. The plug-in works with mono sources and channel counts up to the surround formats supported by the user's DAW. Zynaptiq says its processing uses proprietary, artificial-intelligence-based MAP technology. The 64-bit plug-in runs on macOS 10.15 or newer and Windows 10 or newer, with a two-core CPU minimum. A compatible 64-bit AU, VST, or AAX host processing audio as 32-bit float is also required. Formats differ by platform: macOS supports AU, AAX Native, VST 2.4, and VST 3; Windows supports AAX Native, VST 2.4, and VST 3. The license costs 269.00 USD once, and the latest version has a fully functional 30-day trial. Activation requires an iLok account and internet-connected computer, or a supported optional USB device.
