I want to do some stereo sound stuff with Mathematica on my Macintosh.
Monoaural sound appears to work well. For example,
Play[ Sin[1000/ t], {t,0,1}]
works as expected.
In the MMa 3.0 book, it says, in Appendix A under Play,
"Play[{f1,f2},{t,tmin,tmax}] produces stereo
sound. The left hand channel is given first."
When I do
Play[{Sin[2Pi 240 t],-Sin[2Pi 240 t]}, {t,0,1}, PlayRange -> {-2.,2.}]
I would expect to hear a pure tone out of each speaker. Instead, I hear nothing.
It appears that Mma is adding the two functions, and then sending the sum
to both speakers.
I am running Mma 3.0 on a Power Macintosh 7500/100, with System 7.5.3.
I have two (cheap) speakers attached to the stereo miniplug.
With the Monitors and Sound (version 1.1) control panel I can get
significantly different volumes on the two speakers with the
Sound Out Balance slider.
Any help would be appreciated.
