No, that is not possible. However, if you want to refer to other stuff from within the callback function, just use a closure or a functor. Any callable will do as callback.
Thanks! Closures did the trick for me.
In case somebody is curious how it works, here is some example code:
from pysoundcard import Stream, continue_flag
import time
def make_callback(test_argument):
def callback(in_data, out_data, time_info, status):
print test_argument
return continue_flag
return callback
test_argument = 5 # argument which should be passed to the callback function
callback = make_callback(test_argument)
s = Stream(samplerate=44100, blocksize=8192, callback=callback)
s.start()
time.sleep(5)
s.stop()
Hi,
first off, thanks for this awesome contribution. It makes real-time audio analysis very comfortable.
However, I am wondering, when using callback mode, is it possible to pass arguments other than those given in the signature to the callback function?
Callback function signature from the documentation of pysoundcard.Stream: "callback(input, output, time, status) -> flag"
Thanks in advance!
