arecord is a small command line utility using the Alsa library. So you might use the aplay.c source to add similar functionality to your program (there is only the aplay utility and source; arecord is just a symlink to aplay).

You can download the alsa-utils sources at Download - AlsaProject[^]. For a quick view on the aplay.c source see alsa-utils: aplay/aplay.c Source File - doxygen documentation | Fossies Dox[^].
