Pink Noize Generator

Pink noise is a sound with frequency characteristics similar to natural sounds such as rain and waterfalls. Due to these characteristics, it is expected to reduce ambient noise and promote restful sleep and improved concentration. Some studies suggest that pink noise improves sleep quality, and it is gaining attention as a suitable ambient sound for studying and meditation.

This app has the following features to balance a comfortable user experience with reduced device load:

● Efficient noise generation: Reduces device processing load by generating and repeating a short amount of noise upon startup.

● Selectable sample rate: Supports sample rate switching to adjust sound quality and battery consumption.

● Flexible sound quality adjustment: Stepless adjustment to your preferred sound quality from white noise to pink noise using the seek bar.

● Simple design: Simple and intuitive UI and background playback support make it ideal for long-term use.

● Timer mode: Timer from 5 minutes to 3 hours. A fade-out mode switch ensures it doesn't disturb sleep.

● 40Hz mix mode: 40Hz waves have recently attracted particular attention, and research is progressing rapidly. This app features a 40Hz wave mix mode, and the mix ratio can be freely adjusted.

*40Hz is a very low frequency, so it may not play correctly depending on the performance of your smartphone's speaker. If you cannot hear it, try adjusting the waveform to a square wave or similar.

●Sandstorm screen mode: Press and hold the Play button to display sandstorm in full screen. (Tap the sandstorm to dismiss it)

Enjoy a more comfortable sleep and focused environment through this app.
