FFT spectrum analyzer is a test equipment that uses Fourier analysis and digital signal processing techniques to provide spectrum analysis. Using Fourier analysis it is possible for one value in, for example, the continuous time domain to be converted into the continuous frequency domain, in which both magnitude and phase information are included.

Spectrum analyzer system using a 512-point FFT, in a Cyclone IV FPGA. Reads i2s audio from the codec and then does all FFT/VGA functions. Nios just reads the FFT result and draws the display bars. VGA frame buffer on-chip. VGA signals generated on-chip. See the included video files to watch it in action.

How to develop a Spectrum Analyser from a realtime audio?
https://stackoverflow.com/questions/18293953/how-to-develop-a-spectrum-analyser-from-a-realtime-audio
Basically, I use: mRecorder = new MediaRecorder (); mRecorder.setAudioSource (MediaRecorder.AudioSource.MIC); mRecorder.setOutputFormat (MediaRecorder.OutputFormat.THREE_GPP); mRecorder.setAudioEncoder (MediaRecorder.AudioEncoder.AMR_NB); mRecorder.setOutputFile ("/dev/null"); How I can do a …

The spectrum analyzer above gives us a graph of all the frequencies that are present in a sound recording at a given time. The resulting graph is known as a spectrogram. The darker areas are those where the frequencies have very low intensities, and the orange and yellow areas represent frequencies that have high intensities in the sound.
