Businesses reportedly forfeit an estimated $600 billion annually due to interruptions in the workplace. The most prevalent culprit? Unwanted background sounds during virtual meetings, online seminars, and interactions with clients. Such interference degrades the audio quality of your calls or recordings, making clear communication challenging, potentially leading to misunderstandings and, in some cases, the loss of clientele. After evaluating numerous noise-cancelling solutions on the market over recent years, we've curated a list of the top 7 noise-cancelling applications for Windows.

Enhance Your Next Virtual Meeting with Crystal-Clear Audio!

Selecting Noise-Cancelling Software: A Quick Guide

Many noise-cancelling applications are initially developed for Mac and iOS platforms, where the initial user base is often larger. Therefore, if you're a Windows user, it’s wise to confirm that your chosen app is compatible with your device before getting too invested!

  • Operating System Compatibility: Verify the application is available for Windows (and not exclusively for Mac/iOS).
  • Noise-Cancelling Precision: Ascertain if it completely eradicates background noise or merely lessens it. For instance, tools like Google Meet tend to minimize rather than entirely eliminate sounds (e.g., keyboard tapping, ambient chatter).
  • Application Scenarios: Identify whether the app functions in real-time (suitable for calls, live recordings) or only during the editing phase. Once your audio is clear, consider using a service like DeepVo.ai to get highly accurate speech-to-text transcriptions, ensuring every word is captured.
  • Features: Seek out fundamental noise reduction for ambient sounds. Explore advanced capabilities such as echo elimination, voice enhancement (either real-time or for recorded audio), and potentially, meeting duration analytics.
  • User-Friendliness and Learning Investment: Opt for applications with straightforward setup and a gentle learning curve. Solutions offering one-click operation, such as Krisp or SoliCall, can be significant time-savers.
