The best paid de-reverb plugins for vocal tracks/stems/separations
- RX 11 Dialogue Isolate (RX Editor/VST, paid) - some people like it more than DeVerberate 3. In RX Advanced variant, there’s additionally “multi-band processing and a high-quality mode as an offline process”, good companion for de-echo along with anvuew v2 model for dereverb
- DeVerberate 3 by Acon Digital (someone while comparing said it might be even better than RX10) "I find it's useful to take the reverb only track and unreverbed track and mix them to a nice level" “Acon is probably best if you can tweak to each stem separated. RX is imo too rough.” Comparison
- Accentize DeRoom Pro ("great" but expensive, available in DxRevive Pro, now 1.1.0)
- prime:vocal (multitool with also dereverb and other vocal enhancers)
- DxRevive Pro 1.1.0 - complete dialogue restoration tool; noise removal, reverb suppression, restoration of absent frequencies, elimination of Codec Artifacts
- Izotope RX <?8-10 Dialogue De-Reverb (RX Editor/VST) for voice and mixtures
(more possible free solutions). Good results not only for room reflections, but also regular reverb in vocals. It picks reverb where even FoxyJoy's model fails (“De-reverb” and “Dialogue de-reverb” options). It’s destructive for mixing raw vocals, but can just work.
- Clear by Supertone “equally good compared to RX10 imho. Smoother imho. It's only good on vocals though” Simple 3 knob plugin - “the cleverest / least-manual to get good results and is AI-based.” previously known as Supertone Voice Clarity and defunct free GOYO.AI) Also destructive for mixing raw vocals, but can just work.
- Acon Dialogue:Extract 2 (voice de-reverb and de-noise added in some update; sounds better than Clarity VX - nassemo.8805 [at least the non-DeReverb variant of VX])
- Waves Clarity Vx DeReverb - cannot perform de-echoing, so you need UVR De-echo (17.7kHz cutoff) or RX Dialogue Isolate for it; simpler than RX (paid; models updated in 12/17/2023 build) - same. Maybe you could even mix the two plugins using less aggressive settings in both.
- Hush Pro - noise removal, ML-powered dialogue repair, voice, reverb, noise slidiers
Others:
- SPL De-Verb Plus
- Audio Damage Deverb
- Zynaptiq UnVeil
- Zynaptiq Intensity
- Thimeo Stereo Tool (one of its modules, not so aggressive/capable like Silk Vocal, can be even used on mixbus lightly)
- Cedar StageVox (voice dereverb and denoiser capable of working in real-time for tracking)
- Cedar VoicEX 2 (voice dereverb and denoiser)
- Waves Silk Vocal (voice has optional Live version too)
- Noiseworks VoiceAssist (doesn't give very dry vocals, but it also has some highs recovery option for them after de-reverb, not always free of artefacts, but very decent)
If you want to use some of these DAW plugins for your microphone in real-time, you can use Equalizer APO.
Go to "Recording devices" -> "Recording" -> "Properties" of the target mic -> "Advanced".
To enable a plugin in Equalizer APO select "Plugins" -> "VST Plugin" and specify the plugin dll. You need a VST2 x64 plugin for the x64 app version, VST3 is unsupported, but using a separate chainer/wrapper/adapter from VST2 to VST3 is still possible.
To run a plugin for a microphone in a simple app and send it to any output device, alternatively, you can download savihost3x64, then edit downloaded exe name to the name of your plugin you want to use, placed nearby, and run the app. Now go to settings and set input and output device (can be virtual card, maybe not necessarily). Contrary to Equalizer APO (which supports only VST2 x64 or x86 for x86 app version) it supports VST3 plugins too. Alternatively you can also check free Cantabile Lite (it incorporates JBridge for 32-bit VST2 plugins). Of course, you can also use DAWs for the same purpose (Reaper, Cakewalk etc., and Audacity maybe received some real-time VST support in newer versions, before it was only for offline use)
