Audiotool Android App is made for audio engineer.This audio android app gives you very detailed information about what you hear.This is all in one tool,this android app measures Spectrum Analyzer, Spectrogram, Chart Recorder, Signal Generator, Polarity Checker and much more in this android app.If you try wanna something new in your android phone download these android app.
AudioTools's Spectrum Analyzer component uses FFT on batches of samples recorded at the microphone. Hann windowing reduces aliasing. Recorded spectra may be stored as files on the SD card, and then loaded later and displayed together with the live spectrum.
The deciBel meter component uses IIR filters and exponential averaging to calculate Flat, A and C weighted response at speeds of Fast, Medium and Slow.
RT60 measurements can be made by starting the RT60 component and using a loud clap (or similar) to trigger the measurement. RT60 times measure how much reverberation or echo there is in a room or auditorium.

Wave frequency is set using the arrow buttons or directly via the keyboard. The upper display shows the sound picked up by the microphone in real time. This can be useful for evaluating the response to an audio system being fed with the generated sound. Better results can be obtained by using a headset adapter/splitter that allows an electrical signal to be sent from the device to the audio system.
The Impulse signal is a delta issued approximately once per second. Impulses can be used to measure the frequency response of audio systems: they have a flat frequency distribution.
The accuracy in frequency of the generated periodic signals is quite good: on the Motorola Droid, errors were of the order of 1% throughout most of the range. 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.

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).

The Signal Generator component of AudioTool generates White and Pink Noise, Sine, Square, Triangle and Ramp waves, and Impulses. The generator uses multiple cycled buffers that are refreshed randomly so ensuring truly random White/Pink noise. The Pink Noise algorithm uses Kemmet's method to adjust White Noise into Pink.Wave frequency is set using the arrow buttons or directly via the keyboard.
