No ads no limitations no data collection it works offline and it's free.

It aims at removing background noise like:
- white noise hiss rain sea wind car fans hoover noise etc.

# HOW CAN YOU TEST IT? use 2 devices

-> 1st device: a smartphone with Denoiser App to record your voice
-> 2nd device: a noise generator or a smartphone/laptop/tv where you open YouTube and play something like "10 hours of white noise / rain / driving car etc" in the background. You can try also with a vacuum cleaner hair dryer etc.

It's our first version so please be forgiving. Give us a chance to fix the bug if you found one before you write a bad comment. Just write to us and describe the bug. We will fix it right away! A deal? :-)

If you have any ideas about what we should add to make the app better and more convenient just let us know. We would be happy to make you happier.

FAQ:

Q: How can I obtain the best quality?
A: By recording in the highest quality and the highest sample rate of the audio track. Our algorithm can then recognize the noise more precisely.
Q: Where are the files being saved?
A: Technically it's ExternalStorageDirectory() + "/Download" in many cases this would be "/storage/emulated/0/Download". The easiest way to get there is by using some kind of Files explorer -> go to Internal Memory -> and Download folder. That's it. We are working on choosing a custom save path.
Q: How loud can the noise be?
A: It cannot be too loud. If it's louder than the recorded voice you will not get good results. Technically speaking it would be best if the Signal-to-Noise Ratio (SNR) was 15 dB or more.
