This then almost costs nothing on the performance side for 3D real-time rendering.
It means it’s mainly handled by a dedicated audio chip on your device via native code (the browser). If you want to manage the attenuation (or distance model in Web Audio) using a specific algorithm, you can by-pass the native Web Audio attenuation using Babylon.js custom attenuation function. Creating your own custom attenuation function If you’re inside the space defined by the grey cone, you should hear the music, if not you’ll not hear it as the coneOuterGain is set to 0. You can play with this sample from our playground to better understand the output: Spatial Directional Sound SetLocalDirectionToMesh() is simply the orientation of the cone related to the mesh you’re attached to. Outer angle of the cone must be superior or equal to the inner angle, otherwise an error will be logged and the directional sound won’t work. coneOuterGain: volume of the sound when you’re outside the outer cone (between 0.0 and 1.0).coneOuterAngle: size of the outer cone in degree.coneInnerAngle: size of the inner cone in degree.To run the following examples with top-level await expressions, launch an asynchronous Python REPL using python3 -m asyncio or an IPython shell.
Synchronous API Play a file from play_sounds import play_file, DEFAULT_SONG play_file ( DEFAULT_SONG ) # blocks by default # play without blocking play_file ( DEFAULT_SONG, block = False ) Play while work completes from time import sleep from play_sounds import play_while_running, DEFAULT_SONG with play_while_running ( DEFAULT_SONG ): sleep ( 60 ) Play a file after work completes from time import sleep from play_sounds import play_after, DEFAULT_SOUND with play_after ( DEFAULT_SOUND ): # blocks by default sleep ( 60 ) # play without blocking with play_after ( DEFAULT_SOUND, block = False ): sleep ( 60 ) Ring the terminal bell from play_sounds import bell, bell_after # play bell bell () # ensure the bell is played even if an exception is thrown with bell_after (): raise Exception ( "Bye" ) Asynchronous API There's a synchronous API and an asynchronous API that you can use with the async/await syntax and asyncio. It can use aiopath.AsyncPath objects, too. This library uses pathlib.Path objects when pointing to filenames and paths.
Installation $ python3 -m pip install play_sounds If you're targeting multiple desktop platforms and don't want to get mired down in the details of when and where to use playsound or boombox, or if your project uses async/await, you can just reach for play_sounds and call it a day. Neither boombox or playsound provide asyncio and async/await compatible APIs, but play_sounds does. playsound will play other formats than WAV on Windows, but it requires GStreamer and PyGObject bindings on Linux, while boombox has several playback backends for Linux other than, and including, GStreamer. Rationaleīoombox is great and 90% of the way there, however it is limited to only playing WAV files on Windows. It includes a synchronous API and an equivalent asynchronous API.įor code examples, you can check out onhold and ding, or scroll down to the Usage section. Play_sounds provides a simple cross-platform API to play sounds in Python scripts.
