get_sound_input_cap_rate(3alleg4)				  Allegro manual				 get_sound_input_cap_rate(3alleg4)

NAME

       get_sound_input_cap_rate - Returns the maximum sample frequency for recording. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       int get_sound_input_cap_rate(int bits, int stereo);

DESCRIPTION

       Returns	the maximum possible sample frequency for recording in the specified format, or zero if these settings are not supported. The bits
       parameter is the number of bits of the audio, and stereo is a boolean parameter. Pass zero for mono, non-zero for stereo input. Example:

	  int max_freq;
	  ...
	  /* What frequency can we record 8 bits mono at? */
	  max_freq = get_sound_input_cap_rate(8, 0);
	  if (max_freq > 22000) {
	     /* Ok, 22KHz and above is good enough. */
	  }

get_sound_input_cap_parm(3alleg4)				  Allegro manual				 get_sound_input_cap_parm(3alleg4)

NAME

       get_sound_input_cap_parm - Detects if the specified recording parameters are supported. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       int get_sound_input_cap_parm(int rate, int bits, int stereo);

DESCRIPTION

       Checks whether the specified recording frequency, number of bits, and mono/stereo mode are supported (and how) by the current audio driver.

RETURN VALUE

       The function returns one of the following possible values:

	  0  = It is impossible to record in this format.
	  1  = Recording is possible, but audio output
	       will be suspended.
	  2  = Recording is possible at the same time as
	       playing other sounds (full duplex sound card).
	  -n = Sampling rate not supported, but rate 'n'
	       would work instead.
