WHAT IS IT FOR?
Use Noise Machine with a pair of earphones to mask distracting and annoying sounds and become at peace with the world. Loud conversations at a coffee shop where you are trying to read, crying babies on planes, background music that doesn't agree with your taste and a many other noises get into your brain and have to be processed. All of these sounds have certain patterns and aren't random in the mathematical sense. When you are tired or irritable or are getting too distracted, you can let your brain rest by masking these sounds with noise that doesn't have a noticeable pattern. This works remarkably well even at moderate volumes, and you will be able to concentrate or relax much more easily in noisy environments. Even tinnitus can be masked this way. Noise Machine can also be used with a speaker to help put babies (and adults) to sleep. If you intend to stay awake, it's best to use it with headphones or earphones. That way, at least if you picked the right type of noise and the earphones are comfortable, you will quickly stop noticing it; with speakers, every time you move your head, your perception will change, and you will be reminded of the noise, which defeats the purpose. There are also some technical uses, such as testing speaker polarity.
The terms "white" and "pink" noise refer to random signals with different spectral distributions. In white noise, the noise energy density is constant throughout the frequency spectrum (at least in the range of interest). This is similar to white light, hence the term "white noise". In pink noise, the lower-frequency components are stronger, and the noise energy density is the same in every octave (or decade, or any logarithm of frequency). This is also known as 1/f noise. Similarly, in pink-colored light, the lower-frequency, longer-wavelength, redder components are stronger.
A more general case is 1/f^α. The value of α=0 corresponds to white noise, or flat frequency spectrum, as described above; α=1 corresponds to pink noise, or -3dB/octave frequency dependence, also as described above (in different words); α=2 to "red" or "brown" noise (which refers to Brownian motion rather than the color brown), or -6dB/octave frequency dependence. In this app, the alpha value may be adjusted from 0 to 2 in small increments.
Optionally, the sound may be played in a loop, which reduces the already modest CPU and battery usage by only generating the noise clip that's long enough to fill a loop (at the expense of using more RAM to store it, which normally is not a problem). The playback is gapless. If the loop is too short, you will notice a pattern, which will create a distraction, but even the shortest loop setting (1 minute) should be long enough. The longest setting is determined by the amount of memory available to the app (typically 5 minutes). If you think you can still hear a pattern, or need continuous random signal generation for some other purpose, or want the app to use as little RAM as possible, you can turn the loop off.

*Some android devices refuse to loop gaplessly using the default implementation. Enabling the looping fix should correct this if necessary. However, you may have to experiment with its value for it to work correctly. It should be set high enough to remove the gap and no higher.
This is necessary to detect when a phone call is in progress so that the audio can be paused.

If you need a combined Signal Generator and Spectrum Analyzer with dB SPL, Leq, Spectrogram, and RT60, check out the Android "AudioTool" app.
Recommended by "Sound and Vision" magazine.
Features 1/1, 1/3 & 1/6 octave RTA modes, Leq (wideband, Octave, variable duration), RT60 (wideband, Octave), Spectrogram, Peak frequency, Fast, Medium & Slow filters, Flat & A/C Weighting, Averaging, SPL Chart Recorder, Noise Criteria, White/Pink Noise, Sine, Square, Triangle, Sweep, Ramp and Impulse signals & loudspeaker polarity checker. RTA Store & Load, Hann windows, "Keep Screen On", pinch to zoom, scroll to center.
Exclusive ISO 1/3 Octave Calibration - correct for your phone's microphone response. Octave calibration discs are moved up or down to obtain a flat response, and match the overall SPL to that of an external meter. Save/Restore of Cal files (Dayton Audio iMM-6 also supported).
Use: home theater, audio engineer, car audio, etc
AudioTool FFTs sets of samples recorded at the microphone. Aliasing reduced by Hann windowing. SPL calculated in realtime. Spectra may be saved as files on the SD card, then loaded and displayed with the live spectrum. The "Store" button stores the current live spectrum - "Load" shows a list of stored spectra to select.
To hide the buttons, tap the screen. To restore them, tap again. To zoom the scale, pinch the screen. To move the scale, drag it up or down (left or right).
The deciBel meter uses IIR filters and exponential averaging to calculate Flat, A and C weighted response at speeds of Fast, Medium and Slow speeds.
A pair of cursors can be shown on the RTA and Chart Recorder displays: each can be moved to any position, and will display the SPL & time/frequency values there. Initially, both cursors are positioned mid-screen - simply drag them to a new position with the fingertip. The cursors can be turned on and off in the Menu.
The loudspeaker polarity checker can be used to check whether a loudspeaker is wired in phase: connect the AudioTool output to the speaker under test, select "Polarity" from the signal generator screen, then return to the RTA screen. If the speaker is out of phase (polarity reversed) AudioTool will show "Pol ---", otherwise "Pol +++" if the speaker is in phase.
The Noise Criteria (available from the Menu) function shows a set of NC contours overlaid on the 1/1 Octave RTA display and the calculated real time current NC value is also shown.
The Chart Recorder shows a moving trace of the SPL measurements over the last few minutes.
RT60 measurements can be made by starting the RT60 component using the "RT60" button, and then using a loud clap (or similar) to trigger the measurement. RT60 can also be used with Pink Noise from the AudioTool generator. RT60 times measure how much reverberation or echo there is in a room or auditorium.
The Signal Generator generates White and Pink Noise, Sine, Square, Triangle and Ramp waves, Sine Wave Sweeps and Impulses. The generator uses multiple cycled buffers, refreshed randomly so ensuring truly random White/Pink noise. Pink Noise algorithm uses Kemmet's method to adjust White into Pink.
The frequency accuracy of the generated periodic signals is typically around 1%. Sine wave fidelity is good throughout most of the audio range. Other signals' leading and trailing edges show ringing and decreasing frequency response artifacts in the upper ranges, depending on the Android used.

Try this app to transform your earbuds to noise generating earplugs. Noise Blocker is an app I designed to help you focus in noisy places like work places or coffee shops (esp. when listening to music is too distracting). Some studies show that listening to this type of noise increases deep sleep, enhances brain waves, and improves memory in subjects.
Noise Blocker sends bassy, stereo brown noise through your earbuds, causing other outside noises to gently mix in as ambient sound before hitting your ears. Note that brown noise differs from white noise: white noise sends a signal that emphasizes high treble. This is why brown noise works better than white noise -- it is bass heavy and raises the noise level for bass and treble in a uniform fashion. This will effectively block out all external noise -- even better than ear plugs would.
Enjoy this free version for a limited time, and if you do enjoy it please feel free to rate it. (c) 2013. A. Thomas Tran. All Rights Reserved.
