.\" Generated by the Allegro makedoc utility .TH read_sound_input 3alleg4 "version 4.4.3" "Allegro" "Allegro manual" .SH NAME read_sound_input \- Retrieves the last recorded audio buffer. Allegro game programming library.\& .SH SYNOPSIS .B #include .sp .B int read_sound_input(void *buffer); .SH DESCRIPTION Retrieves the most recently recorded audio buffer into the specified location. The buffer size can be obtained by checking the return value from start_sound_input(). You must be sure to call this function at regular intervals during the recording (typically around 100 times a second), or some data will be lost. If you are unable to do this often enough from the mainline code, use the digi_recorder() callback to store the waveform into a larger buffer of your own. Note: many cards produce a click or popping sound when switching between record and playback modes, so it is often a good idea to discard the first buffer after you start a recording. The waveform is always stored in unsigned format, with stereo data consisting of alternate left/right samples. .SH "RETURN VALUE" The function will return non-zero if a buffer has been copied or zero if no new data is yet available (you were too fast checking the input). .SH SEE ALSO .BR start_sound_input (3alleg4)
