Reads from standard input.
Expects type of SPFLOAT, which by default is a float. If the input data is larger than the number of samples, you will get a complaint about a broken pipe (but it will still work). If there is no input data from STDIN, it will hang.
The expected use case of sp_in is to utilize pipes from the commandline, like so:
cat /dev/urandom | ./my_program
Assuming my_program is using sp_in, this will write /dev/urandom (essentially white noise) to an audio file.
sp_in_create(sp_in **in)
sp_in_init(sp_data *sp, sp_in *in)
sp_in_compute(sp_data *sp, sp_in *in, SPFLOAT *dummy, SPFLOAT *out)
sp_in_destroy(sp_in **in)
Outputs
out: Signal output.
