Features

• Plays an alert when rendering is complete
• Supports a default system beep
• Supports custom sound files
• Adds controls to the Render Properties panel
• Adds controls to the 3D Viewport N-panel
• Includes a test button for checking the selected alert sound

Audio Format Support

On Windows, .wav files can be played with Python's winsound.

For other formats, Render Alert uses Blender's built-in aud module. Blender's audio API can load sound files such as .ogg, and its documented codec/container list includes formats such as MP3, OGG/Vorbis, FLAC, and WAV. 【2-a72853】

Recommended formats:

• .wav
• .ogg
• .mp3
• .flac

Actual playback support can still depend on the Blender build and the audio file itself.
