Colored Noise Generator for Android

11 things about Colored Noise Generator

1. Octave band noise is generated the multiple frequency divided band signal by using the band-pass filtering of 1/N (N is a natural number) octave band.

2. Octave band noise can be created as a multi-band coupling signal by 1/1 octave band filter with a center frequency from 63Hz to 8kHz.

3. For example, by selecting the pink noise and playing the 1/1 octave band noise in the order of 125Hz, 1KHz, 8kHz of the center frequency, you can determine the intensity of each frequency band on the audibility.

4. - 1/1 Octave band noise : 8 types, center frequency - 63Hz, 125Hz, 250Hz, 500Hz, 1kHz, 2kHz, 4kHz, 8kHz.

5. In addition, it can generate a specific octave band noise signal by using the band-pass filtering of 1/1 octave band with ideal steep attenuation characteristics.

6. The power spectral density is a noise signal that drops by 3 dB per octave as the frequency rises.

7. The power spectral density is a noise signal that drops by 6 dB per octave as the frequency rises.

8. In order to further measure in detail, Octave band noise will be able to take advantage of the testing noise signal that some part of the octave band is divided.

9. Power spectral density is a noise signal that increases by 6 dB per octave as the frequency rises.

10. Power spectral density is a noise signal rising by 3 dB per octave as frequency goes up.

11. Octave band noise can be used for various purposes as a reference sound source for environmental sound measurement, sound tuning, tinnitus relief and sound masking.
