![]() You do have to play around with the knobs to get it set up right, or you can introduce weird artifacts. you can sample the noise, then “freeze” the profile which locks it in - so CPU load is reduced after that.Īdditionally, Acon has a De-reverbator that I use in conjunction with the Denoiser to take out room flutter echoes that happen as you speak. I record voiceovers on the road from hotel rooms, and Acon’s Denoiser allows me to record damn-near-booth-quality VO tracks using a condenser mic in an untreated hotel room with the A/C and fridge running!! No more pillow forts or blanket tents (which don’t really work anyways). Not mentioned in the article is AconDigital’s Restoration Suite ($100). So far, they’re the only company I know of that has included this type of feature in a DAW-based noise-reduction plugin. Izotope takes a unique and especially transparent tool for removing plosives and intermittent interferences in RX2: next-generation Spectral Analysis. Specialized tools are now available from the cutting-edge developers at Cedar and even as part of Wave Arts’ specialized noise reducer package, Dialog, that help clean up these problem areas without effecting the surrounding audio. ![]() To this day, the biggest problem automated processors have with these low low-frequency aberrations is not with eliminating them but with identifying them in the first place. Until very recently, pops and plosives were usually best taken care of by hand, through the judicious use of high-pass filters and gain rides on tiny snippets of audio. But similar results can be had with any bank of simple notch filters and little bit of setup.) (For those of you who only need a hum reducer, the most cost-effective option is probably McDSP’s NF575 hum filter for only $130 Native, and as a welcome addition to their bundles. By simply turning up that single fader as far as possible before artifacting began to set in, there were many cases in which when the NS-1 allowed me to obtain results that matched or surpassed its big brothers, and in significantly less time. Surprisingly, even once the learning curve is overcome, one of the most effective noise reducers from Waves turns out to be the NS-1 from their “Single Knob” series, street price: only $99. ![]() In practice, they might not be quite as effective as a Cedar system, but they carry 1/10th the price tag, and the WNS’ welcome “suggest” function can be a great shortcut and learning aid for new users. Waves has recently taken a step into this world, releasing the WNS and the W43, their own versions of these no fader-based no-latency noise reducers. Still, the Cedar DNS series remains among the most popular noise reducers in broadcast and post circles thanks to its super-low latency, hardware integration, and a proven record for cleaning up dialog tracks in real-time. ![]()
