Following is the screenshot of the program in Max. The code is cleaned as much as possible, and self-explanatory. However, if for any reason you have a specific question, please email us here.

The next screenshot shows the final interface of the application. Here follows a short explanation: user can select  from a number of available sound sources from panel A, set source volume and audio DSP settings from panel B, and use the spectrum analyzer (panel F) to visualize the sound activity. 

The first sound source option (SineWaves) can be used in combination with panel C, setting 32 independent sine wave frequencies (from 20Hz to 20kHz).

Second option is Sweep, and with the use of panel D the user can set a specific sine frequency across the sound spectrum, but also to create a sweeping frequency range between a start and stop frequency during a specific amount of time.

Third and fourth option set different noise types - white and pink. Firth option allows the user to use the audio input of the computer (Line In, or Microphone), and last option to use an audio file (.wav, .aiff). Settings for the sampler are found on panel E; including a filter with options for filter type, gain, and resonance controls.
