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, making it a suitable ambient sound for studying and meditation.
This app features the following characteristics to balance comfortable use 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: Steplessly adjust sound quality from white noise to pink noise using the seek bar.
● Ambient sound presets: In addition to pink noise, it includes three noise types that mimic rain, waves, and drafts. Switch to your preferred ambient sound with a single button.
● Noise controller: Supports detailed customization using filters (BPF/HPF, etc.) and LFO (volume control). You can freely adjust the sharpness of the wind noise and the speed of the wave fluctuations.
● Simple Design: The simple and intuitive UI and background playback support make it ideal for long-term use.
● Timer Mode: A timer from 5 minutes to 3 hours. The fade-out mode switch ensures it won't disturb your sleep.
● 40Hz Mix Mode: 40Hz waves have recently attracted significant attention and are being researched extensively. 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 can't hear it, try adjusting the waveform to a square wave, etc.
● Sandstorm Screen Mode: Press and hold the Play button to display sandstorms in full screen. (Tap the sandstorm to dismiss it.)
