Quick Start Guide

Rpaudio can be use in both synchronous and asynchronous Python code. To quickly get started with rpaudio, follow these steps:

1. Install rpaudio:

   pip install rpaudio
   

2. Use rpaudio in your synchronous Python code:

   import rpaudio
   import time
   
   kill_audio = False
   AUDIO_FILE = r"C:\Users\16145\Desktop\a1.mp3"
   
   def on_audio_stop():
       global kill_audio
       kill_audio = True
       print("Audio has stopped")
   
   def play_audio():
       # Initialize and load the audio file
       handler = rpaudio.AudioSink(callback=on_audio_stop).load_audio(AUDIO_FILE)
   
       # Set the volume to 50% (optional)
       handler.set_volume(0.5)
       handler.play()
   
       # Loop until the audio completes, print the time elapsed
       i = 0
       while not kill_audio:
           i += 1
           time.sleep(1)
           print(i)
   
   if __name__ == "__main__":
       play_audio()
   

3. Use rpaudio in your asyncio Python code:

   import rpaudio
   import asyncio
   from rpaudio import FadeIn, FadeOut, ChangeSpeed
   
   kill_audio = False
   AUDIO_FILE = r"C:\Users\16145\Desktop\code_24\frpaudio\rpaudio\examples\ex.wav"
   
   
   def on_audio_stop():
       global kill_audio
       kill_audio = True
       print("Audio has stopped")
   
   
   async def play_audio():
       handler = rpaudio.AudioSink(callback=on_audio_stop).load_audio(AUDIO_FILE)
       print(handler.metadata)
   
       fade_in_effect = FadeIn(start_val=0.0, end_val=1.0, duration=3.0)
       fade_out_effect = FadeOut(duration=2.0)
       speed_up = ChangeSpeed(apply_after=1.0, end_val=1.5, duration=3.0)
   
       effects_list = [fade_in_effect,  fade_out_effect, speed_up]
       handler.apply_effects(effects_list)
   
       handler.play()
   
   
       while not kill_audio:
           await asyncio.sleep(1)
   
   
   async def sleep_loop():
       global kill_audio
       i = 0
       while not kill_audio:
           await asyncio.sleep(1)
           i += 1
   
   
   async def main():
       await asyncio.gather(play_audio(), sleep_loop())
   
   asyncio.run(main())
