@section sine
Generate an audio signal made of a sine wave with amplitude 1/8.
The audio signal is bit-exact.
It accepts a list of options in the form of @var{key}=@var{value} pairs
separated by ":". If the option name is omitted, the first option is the
frequency and the second option is the beep factor.
The supported options are:
@table @option
@item frequency, f
Set the carrier frequency. Default is 440 Hz.
@item beep_factor, b
Enable a periodic beep every second with frequency @var{beep_factor} times
the carrier frequency. Default is 0, meaning the beep is disabled.
@item sample_rate, s
Specify the sample rate, default is 44100.
@item duration, d
Specify the duration of the generated audio stream.
@item samples_per_frame
Set the number of samples per output frame, default is 1024.
@end table
@subsection Examples
@itemize
@item
Generate a simple 440 Hz sine wave:
@example
sine
@end example
@item
Generate a 220 Hz sine wave with a 880 Hz beep each second, for 5 seconds:
@example
