6. pyaudio를 사용하여 음악 재생하기

1.  필요한 라이브러리를 설치한다.

2. pygame 모듈을 사용하여 mp3를 재생하는 코드를 제작한다.

import sys

import pygame as pg

def play_music(music_file, volume=0.8):

    # set up the mixer

    freq = 16000    # audio CD quality

    bitsize = -16    # unsigned 16 bit

    channels = 1     # 1 is mono, 2 is stereo

    buffer = 1024 * 2  # number of samples (experiment to get best sound)

    #pg.mixer.quit()

    pg.mixer.init(freq, bitsize, channels, buffer)

    #pg.mixer.init()

    # volume value 0.0 to 1.0

    pg.mixer.music.set_volume(volume)

    clock = pg.time.Clock()

    try:

        pg.mixer.music.load(music_file)

        print("Music file {} loaded!".format(music_file))

    except pg.error:

        print("File {} not found! ({})".format(music_file, pg.get_error()))

        return

    pg.mixer.music.play()

    while pg.mixer.music.get_busy():

        # check if playback has finished

        clock.tick(10)

    pg.quit()

# pick a MP3 music file you have in the working folder

# otherwise give the full file path

# (try other sound file formats too)

if __name__ == '__main__':

    music_file = sys.argv[1]

    # optional volume 0 to 1.0

    volume = 0.8

    play_music(music_file, volume)

3. 재생!

* 재생 주파수를 낮게해서 웅장한 나팔바지가 .... 적정히 Freq를 조절하자.
