-.SH NAME
-pplay \- visual PCM audio player
-.SH SYNOPSIS
-.B pplay
-[
-.B -cfs
-] [
-.B pcmfile
-]
-.SH DESCRIPTION
-.I Pplay
-is a PCM audio player which shows a time-domain graphical plot of the data.
-It operates on the same format used by the audio device (see
-.IR audio (3)).
-.PP
-At startup, the program loads the audio data in its entirety into memory,
-unless the
-.B -f
-option is given, in which case the input file must be seekable.
-Data is read either from the file provided as argument, or from standard in.
-By default,
-.I pplay
-writes audio data back to
-.BR /dev/audio .
-With the
-.B -c
-option, it writes to standard out instead.
-.PP
-The graphical plot shows a time-domain representation of the audio data's left channel.
-The
-.B -s
-option enables plotting its right channel below the left.
-.PP
-The current position in the buffer is shown by a vertical line.
-It can be set using the left mouse button.
-.PP
-.I Pplay
-loops a section of the audio data indefinitely.
-At start up, this section is set to the entire file.
-The section's beginning and end are shown by vertical markers of the same color.
-Both are set by using the middle mouse button,
-relative to the current position in the buffer:
-clicking to the left of the position marker will set the loop start position, and vice versa.
-The
-.B r
-key resets both loop positions to their default values.
-.PP
-By default, the graphical plot spans the dimensions of the window.
-It can be zoomed in or out with the
-.L +
-and
-.L -
-keys, and reset with the
-.L z
-key.
-The
-.L _
-and
-.L =
-keys zoom in by greater increments.
-The view can then be moved by holding the right mouse button,
-and moving the cursor horizontally.
-.PP
-The space key pauses playback.
-The
-.L b
-key resets the position to that of the loop start position.
-.PP
-The
-.L w
-key prompts the user to enter a file path to write the looped section to.
-.SH EXAMPLES
-Load and play an mp3 file (see
-.IR audio (1)):
-.IP
-.EX
-% audio/mp3dec <file.mp3 | pplay
-.EE
-.PP
-Use
-.IR play (1)
