Koala Noise Suppression has become the developer’s choice, especially for real-time audio enhancement. Developers can embed Koala Noise Suppression into their applications in minutes to enable speech enhancement and background noise reduction, resulting in improved engagement with high-fidelity media and premium audio features.

When to use Audio Enhancer?

Any scenario that requires consistent and tonally correct speech can benefit from speech enhancement - whether audio or video, recorded in the past, or streaming in real time. Some popular use cases are below:

Call Centers

Improves service quality by removing background noise, such as phone ringing or agents speaking and typing.

Real-time Agent Coaching

Boosts agent confidence by removing disruptive noise from all sides of the call and enhancing the accuracy of AI-generated responses with higher speech intelligibility.

Virtual Meetings

Fosters employee productivity in virtual meetings by keeping the focus on the speaker and excluding other voices in the background - even though they connect from noisy cafes, open offices, or homes.

Live Streaming

Elevates listener and viewer experience by enhancing the speakers’ voice clarity - whether broadcasting for national television or Twitch.


Enhances speech, making voice recordings sound as recorded in a professional studio without requiring a post-production clean-up. Yet, Koala Noise Suppression is effective in post-production, too!


Allows patients to understand healthcare providers easily by minimizing distractions in the background, even if healthcare providers have to connect from busy places like emergency rooms.
