It supports several file formats and multiple soundcards with -multiple devices. If recording with interleaved mode samples the file is -automatically split before the 2GB filesize. - -\fBaplay\fP is much the same, only it plays instead of recording. For -supported soundfile formats, the sampling rate, bit depth, and so -forth can be automatically determined from the soundfile header. - -If filename is not specified, the standard output or input is used. The \fBaplay\fP utility accepts multiple filenames. - -.SH OPTIONS -.TP -\fI\-h, \-\-help\fP -Help: show syntax. -.TP -\fI\-\-version\fP -Print current version. -.TP -\fI\-l, \-\-list\-devices\fP -List all soundcards and digital audio devices -.TP -\fI\-L, \-\-list\-pcms\fP -List all PCMs defined -.TP -\fI\-D, \-\-device=NAME\fP -Select PCM by name -.TP -\fI\-q \-\-quiet\fP -Quiet mode.
