02-read-from-disk-2.py - Catching the `end-of-file` signal from the SfPlayer object.
============================================================================================================================================
This example demonstrates how to use the `end-of-file` signal
of the SfPlayer object to trigger another playback (possibly
with another sound, another speed, etc.).
When a SfPlayer reaches the end of the file, it sends a trigger
(more on trigger later) that the user can retrieve with the
syntax :
variable_name["trig"]
.. code-block:: python
from pyo import *
import random
s = Server().boot()
# Sound bank
folder = "../snds/"
sounds = ["alum1.wav", "alum2.wav", "alum3.wav", "alum4.wav"]
# Creates the left and right players
sfL = SfPlayer(folder + sounds[0], speed=1, mul=0.5).out()
sfR = SfPlayer(folder + sounds[0], speed=1, mul=0.5).out(1)
# Function to choose a new sound and a new speed for the left player
def newL():
sfL.path = folder + sounds[random.randint(0, 3)]
sfL.speed = random.uniform(0.75, 1.5)
sfL.out()
# The "end-of-file" signal triggers the function "newL"
tfL = TrigFunc(sfL["trig"], newL)
# Function to choose a new sound and a new speed for the right player
def newR():
sfR.path = folder + sounds[random.randint(0, 3)]
sfR.speed = random.uniform(0.75, 1.5)
sfR.out(1)
# The "end-of-file" signal triggers the function "newR"
tfR = TrigFunc(sfR["trig"], newR)
