Published byIRIS Team

Whether in a noisy call centre or a gaming chair, clear sound quality can make or break the experience. This guide explores the five best noise cancelling apps and background noise reduction tools, ensuring your calls, meetings, and recordings are the highest possible quality.

IRIS Clarity

IRIS Clarity is a leading AI noise removal app that has carved out a distinct place in digital communication — particularly in calls, meetings, and call centre environments. Using advanced noise cancelling software, IRIS Clarity focuses on enhancing speech clarity by isolating the speaker's voice from any background noise during calls using bidirectional voice isolation. This unique capability makes it the go-to noise cancellation app for professionals and organisations prioritising clear, effective communication (you can try it for free for 7 days).

Unmatched clarity in calls and meetings

IRIS Clarity addresses the problem of background noise through AI voice isolation, ensuring that the speaker's voice is heard clearly without interference from background noise. AI noise cancellation doesn’t just suppress; it enhances the speaker's voice, making it more prominent and easier to understand. For virtual meetings and calls, where clarity of speech can significantly impact productivity and comprehension, IRIS Clarity stands out.

Robust AI voice isolation

Call centres stand to benefit immensely from IRIS Clarity's AI technology. By removing background noise, call centre agents can communicate more effectively with customers, leading to improved customer satisfaction and reduced handling time. IRIS Clarity's technology also aids in enhancing the accuracy of speech analytics tools, which are vital for analysing call quality and agent performance. The ability to isolate the customer's voice from noise allows for more accurate transcription and analysis, providing valuable insights into customer interactions.

A testament to IRIS Clarity’s capabilities is its recent collaboration with IndyCar, IRIS Clarity has been instrumental in delivering crystal-clear radio transmissions during broadcasts, effectively removing background noise from one of the loudest sports environments. The removal of open wheel racing noise demonstrates how its AI voice isolation software can be applied in almost any situation.

Advanced AI for real-time noise suppression

At the heart of IRIS Clarity's effectiveness is its advanced AI algorithm, trained on thousands of hours of audio data to distinguish between the human voice and background noise accurately. This training enables the software to isolate and enhance the speaker's voice in real-time, providing a seamless and stress-free listening experience. Whether it's the hum of an air conditioner, chatter from a crowded room, or the keyboard typing, IRIS Clarity's AI efficiently filters out distractions, allowing the focus to remain on the conversation.


IRIS Clarity offers simple integration options for both individual users and organisations. Its compatibility with a wide range of communication platforms ensures that businesses can implement the technology without disrupting their current operations. Moreover, the intuitive interface of IRIS Clarity makes it accessible to users of all technical skill levels, ensuring widespread usability across different sectors.

Headsets with built-in noise cancellation

Headsets with built-in noise cancellation technology have become essential for individuals seeking high-quality audio experiences, whether for music listening, gaming, professional calls, or remote work. These devices employ advanced technology to eliminate unwanted background noise, allowing users to focus on their audio content without distractions. When combined with software solutions like IRIS Clarity, these headsets can offer an even more refined and immersive audio experience.

Noise control

Noise-cancelling headsets use active noise control (ANC) technology to reduce unwanted ambient sounds. This involves using built-in microphones to detect external noise and then generating sound waves that are the exact opposite (anti-noise) to cancel it out. The result is a significantly quieter listening environment, where the primary audio is clear and uninterrupted by background noise.

Isolated experience

Music enthusiasts and gamers alike appreciate the pure, immersive sound experience that noise-cancelling headsets provide. By isolating the audio content from any external noise, these headsets deliver rich, detailed sound quality, allowing users to hear their music or game audio as the creators intended.

Compatibie with IRIS Clarity

When paired with noise cancellation software like IRIS Clarity, noise-cancelling headsets become even more powerful. IRIS Clarity's advanced AI-driven technology works in tandem with the headset's noise cancellation to isolate and enhance speech during calls and meetings. This combination ensures that the user's voice is transmitted clearly, free from both background noise and distractions, making it an ideal setup for call centres, remote work, and any professional communication scenario.

Best for multi-purpose personal use

  • Concentration in noisy environments: They enable users to create a personal sense of calm, even in the busiest settings, enhancing concentration and task efficiency.
  • Clearer calls and meetings: In conjunction with IRIS Clarity, these headsets ensure that voice communications are crystal clear, improving the quality of professional interactions.
  • Immersive audio experience: Whether for music, gaming, or movies, noise-cancelling headsets provide an unrivalled audio experience by focusing solely on the sound you want to hear.
