Soundfunktionen

[msw-home]

Hallo, ist es mit dem Blockprogramm möglich, verschiedene Soundfolgen abzuspielen, z.B. Motorgeräusch, oder Tierstimmen?

Hi Manfred,

All I ever did with sound is a sequence of notes that mimic Woody Woodpecker (Got them from David) and a Dutch fire-engine sound.
Tried to make it in block coding.
The fire engine sound I have is

siren_notes = [
    "G#4/4._", "B4/4.", "R/32"
    # , "G#4/4_", "B4/4.", "R/16",
]

But woody is a lot of typing to get the notes in a variable, I am better in copy / paste python 😄

The program of Woody WoodPecker in block coding picture:

The blockcoding in python (So can be copied and pasted to get the block coding again):

I do not know if new features for sound (files) are planned. But first there should be a file system to be used.
So in fact I doubt it.
