    Eliminate background noise and enhance audio quality on calls and recordings with this AI tool

    Nothing can ruin a work call like random background noise. (“Sorry, this is the only time my neighbor has to vacuum, play the trumpet, and practice tap dancing.”)

    Remote meetings are so popular because of the convenience, so scheduling important conversations during late-night quiet hours doesn’t make any sense.

    If only there was an AI-powered tool that could isolate your voice and make it sound like you’re speaking in absolute silence.

    Make way for CrystalSound.

    Delayed response time 🌎

    Hi, Sumo-lings!

    I want to explain why I might not be able to reply to your questions and comments right away. I’m in GMT+7 time zone, which is 12 hours ahead of CST. This means that when you are starting your day, I’m ending mine, and vice versa. However, I will do my best to answer all of your questions as quickly as possible. I appreciate your understanding and patience.

    I also want to share with you the story behind my app and how it came to life. was originally an in-house app during Covid19 at my previous company, where we had to work remotely and communicate online. We were unhappy with the existing noise reduction applications because they distorted speech too much and made it difficult to understand each other. As a speech processing geek, I wanted to fix that and create an app that could preserve the naturalness and clarity of speech while reducing noise, echo, howling, and reverberation. That’s how CrystalSound was born. Later, we decided to spin off and launch our app as an independent product. We are thrilled to have a chance to be on AppSumo and share it with the world.

    This is my first app launch ever and I know it’s not perfect. I’m here to learn from you and to provide you with the best service possible. Please let me know if you encounter any issues or have any suggestions for improvement. Your feedback will help me improve the app and add more features in the future. Some of the features I’m planning to add are real-time speech summarization and real-time speech translation. These features will make your online meetings more productive and accessible.

    Thank you for your support and interest in I hope you enjoy using the app and find it useful for your online communication needs.
