--002215047437bc2308048d6ef206 Content-Type: text/plain; charset=ISO-8859-1 Dear List, I am trying to create a piece of software that will allow a subject to change the beat frequency and amplitude of a signal while listening to it in real time. More specifically, the signal will consist of two pure tones (e.g. T1 + T2), and the difference between them (T2 - T1) as well as the root mean square amplitude will be under the control of the subject via the keyboard. I have tried to execute this in Matlab using a loop, the problem is that the sound stops and then starts again at the beginning of each loop iteration. Can anyone suggest a way this might be implemented on a computer? Or perhaps just a suitable programming language? Thanks, Dan Bowling --002215047437bc2308048d6ef206 Content-Type: text/html; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable <div>Dear List,</div><div><br></div><div>I am trying to create a piece of s= oftware that will allow a subject to change the beat frequency and amplitud= e of a signal while listening to it in real time.=A0</div><div><br></div><d= iv> More specifically, the signal will consist of two pure tones (e.g. T1 + T2)= , and the difference between them (T2 - T1) as well as the root mean square= amplitude will be under the control of the subject via the keyboard.</div> <div><br></div><div>I have tried to execute this in Matlab using a loop, th= e problem is that the sound stops and then starts again at the beginning of= each loop iteration.</div><div><br></div><div>Can anyone suggest a way thi= s might be implemented on a computer?
