title: Is there a way to generate pure tone at a specfic sound pressure level in android?
body: <p>I am new to Android and I am now finding a way to create pure at different frequencies and at different sound pressure level (dB SPL). I have been reading some other sample codes, however, many answers reflected that one must be calibrated before generating a tone of specific sound pressure level. </p>
  
  <p>Is there any way to specify a tone's sound pressure level?</p>
  
  <p>The magnitude can be find easily by certain method(is it?), but I don't know the mathematical relationship between magnitude and sound pressure. If I can convert magnitude to sound pressure, it will be easy to convert it into dB SPL</p>
