Check out this Voice Noise Remover app. It works 100% offline and is available for both iOS and Android. The app makes it easy to remove background noise from voice recordings directly on your device without requiring an internet connection. Simply record a new audio clip or upload an existing recording from your phone, then start the noise removal process. You can compare the original audio with the denoised version, and the difference in audio quality can be heard immediately.

Once the processing is complete, the background noise is significantly reduced, making the voice much clearer. The processed audio can then be saved to the Files app or shared directly with others. The free version supports audio recordings of up to one minute. Give it a try.

Thank you very much.
