#
把一个多声道音频分解成两个单声道
#
index[0]为左声道
#
index[1]为右声道
#
sounds=sound.split_to_mono()
#
print(sounds)
#
将两个单声道合并成多声道
#
stereo_sound = AudioSegment.from_mono_audiosegments(sounds[0], sounds[1])
#
# 取得音频的分贝数
#
loudness = sound.dBFS
#
print(loudness)
#
# 获取音频音量大小,该值通常用来计算分贝数(dB= 20×lgX)
#
loudness = sound.rms
#
print(loudness)
#
# 取得音频的声道数
#
channel_count = sound.channels
#
print(channel_count)
#
# 取得音频文件采样宽度
#
bytes_per_sample = sound.sample_width
#
print(bytes_per_sample)
#
# 取得音频文件采样频率
#
frames_per_second = sound.frame_rate
#
print(frames_per_second)
#
#取得音频文件帧宽度
#
bytes_per_frame = sound.frame_width
#
print(bytes_per_frame)
#
#取得音频中的最大振幅
#
normalized_sound = sound.apply_gain(-sound.max_dBFS)
#
print(normalized_sound)
#
#取得音频的持续时间,同 len()
#
print(sound.duration_seconds)
#
print((len(sound) / 1000.0))
#
#取得音频数据
#
raw_audio_data = sound.raw_data
#
# print(raw_audio_data)
#
#取得音频的frame数量
#
number_of_frames_in_sound = sound.frame_count()
#
number_of_frames_in_200ms_of_sound = sound.frame_count(ms=200)
#
print(number_of_frames_in_sound)
#
print(number_of_frames_in_200ms_of_sound)
#
拼接sound1与sound2,返回一个新的AudioSegment实例
#
cossfade:交叉渐变间隔 ms
#
no_crossfade1 = sound.append(sound2, crossfade=5000)
#
print(no_crossfade1)
#
no_crossfade1.export(r'cc.wav',format='wav') # 输出
#
把sound2覆盖在sound1上,两个音频文件会叠加,如果sound2较长,则会被截断。
#
参数:
#
position:覆盖起始位置(毫秒)
#
loop:是否循环覆盖(true/false)
#
times:重复覆盖次数(默认1)
#
gain_during_overlay:调整被覆盖音频的音量(eg,-6.0)
#
played_togther = sound.overlay(sound2)
#
# sound2_starts_after_delay = sound.overlay(sound2, position=5000)
#
# volume_of_sound1_reduced_during_overlay = sound.overlay(sound2, gain_during_overlay=-8)
#
# sound2_repeats_until_sound1_ends = sound.overlay(sound2, loop=True)
#
# sound2_plays_twice = sound.overlay(sound2, times=2)
#
played_togther.export(r'dd.wav',format='wav') # 输出
#
调整音量大小
#
louder_via_method = sound.apply_gain(+3.5) # 提高
#
quieter_via_method = sound.apply_gain(-5.7) # 减小
#
参数:
#
to_gain:淡出结束时音频音量下降到的分贝数
#
from_gain:设置淡出前的所有音频分贝数
#
start:淡出的起始位置
#
end:淡出的结束位置
#
duration:淡出持续时间
#
fade_in_the_hard_way = sound.fade(from_gain=-120.0, start=0, duration=5000)
#
fade_out_the_hard_way = sound.fade(to_gain=-120.0, end=0, duration=5000)
#
反向输出
#
sound.reverse().export(r'ee.wav',format='wav') # 输出
#
调整多声道音频的左右声道音量
#
如果单声道音频调用此方法,它将先被转换为多声道
#
stereo_balance_adjusted = sound.apply_gain_stereo(-6, +2)
#
#左右声道平衡,按百分比增大一边,减小另一边
#
# pan the sound 15% to the right
#
panned_right = sound.pan(+0.15)
#
# pan the sound 50% to the left
#
panned_left = sound.pan(-0.50)
#
# 基于DSP的渲染
#
# 产生一个反向信号的副本,来消除反相位波,或者降低噪音
#
sound.invert_phase()
个人感悟:
一个人最好的镜子就是自己,你眼中的你和别人眼中的你,不是一回事。有人夸你,别信;有人骂你,别听。一根稻草,扔街上就是垃圾;捆上白菜就是白菜价;捆上大闸蟹就是大闸蟹的价。
一个人,不狂是没有出息的,但一直狂,肯定是没有出息的。雨打残花风卷流云,剑影刀光闪过后,你满脸冷酷的站在珠峰顶端,傲视苍生无比英武,此时我问你:你怎么下去?
改变自己就是改变自己的心态,该沉的时候沉下去,该浮的时候浮上来;不争名夺利,不投机取巧,不尔虞我诈;少说、多听、多行动。人每所谓穷通寿夭为命所系,岂不知造物之报施,全视人之自取。
座佑铭:每一个不曾起舞的日子,都是对生命的辜负。
