【python】可指定时间播放音频噪声,t11te（利用python发出特定频率的声音）

文件名：【python】可指定时间播放音频噪声,t11te 【python】可指定时间播放音频噪声

【诉求】

A是一段音频，它有个长度是9秒，A_2就是播放A段音频的前2s。传入播放的时间time，效果是播放对应时常的音频。抽象出来：time = 输出音频的种类对应的长度

str audioList = [A,B,C] Int audioLength = [9,9,10] All_audio_Length = 28

time 如果播放时间time是7s，播放A_7 如果播放时间time是14s，播放A + B_5 如果播放时间time是20s，播放A + B + C_2 如果播放时间time是30s，播放A + B + C + A_2

【实现】

def test(time):result = ""audioList = ["A","B"]audioLengtList = [9,9]curTime = 0i = 0while time > curTime:for i in range(len(audioList)):curTime += audioLengtList[i]if result != "":result += "+"if time > curTime:result += audioList[i]continueelif time == curTime:result += audioList[i]breakelif time < curTime:needless = curTime - timeneed = audioLengtList[i] - needlessresult += audioList[i] + "_" + str(need)breaki = i % len(audioList)print(result)return resultif __name__ == '__main__':test(50)

【调用pygame实现音频播放】
