A simple wrapper around un4seen.com's BASS audio library to enable playing various format media files from python.

Stock python usage

from argparse import ArgumentParser

from pybass3 import Song
import time

def main(song_file):
    song = Song(song_file)
    song.play()
    len_bytes = song.duration_bytes
    position_bytes = song.position_bytes
    print("Playing: ", song_file)
    print(f"Bytes: {len_bytes=}")

    while position_bytes < len_bytes:
        print(song.position, song.duration)
        time.sleep(1)


if __name__ == "__main__":
    parser = ArgumentParser()
    parser.add_argument("song_file")
    args = parser.parse_args()

    main(args.song_file)

Windows playlist example

import pathlib
import time
import argparse
import msvcrt

from pybass3 import Song
from pybass3.playlist import Playlist




def kbfunc():
    x = msvcrt.kbhit()
    if x:
       ret = ord(msvcrt.getch())
    else:
       ret = 0

    return ret


def main(dir_path):
    dir_path = pathlib.Path(dir_path)

    playlist = Playlist()
    playlist.add_directory(dir_path, recurse=True)

    playlist.play()
    play_indefinitely = True
    while play_indefinitely:
        try:
            print(playlist.current.file_path.name, playlist.current.position, playlist.current.duration)
            playlist.tick()
            key = kbfunc()
            if key:                
                if key == 122: # Z
                    print("Previous")
                    playlist.previous()
                elif key == 98: # B                    
                    print("Next")
                    playlist.next()
                elif key == 120: # X
                    print("Play")

                    print("Pause")    
                    playlist.pause()
                elif key == 118: # v
                    print("Stop")
                    playlist.stop()
            else:
                time.sleep(1)
                
        except KeyboardInterrupt:
