The entire SoX functionality is available using just the ‘sox' command, however, to simplify playing and recording audio, if SoX is invoked as ‘play', the output file is automatically set to be the default sound device and if invoked as ‘rec', the default sound device is used as an input source. The heart of SoX is a library called ‘Sound Tools'. Those interested in extending SoX or using it in other programs should refer to the Sound Tools manual page: libst(3). The overall SoX processing chain can be summarised as follows: Input(s) → Balancing → Combiner → Effects → Output > Any takers -- or suggestions how I can do this on a Mac? You should be able to get sox on OSX. I'd imagine it's either easily to install via a package or it's on fink. Either way you shouldn't have much trouble. This way you can just use the shell to do the work. You can do it in PHP or in any other kind of script. Hope this helps.
