+ 4/2 追記 --ここから
66
+
67
+
68
+
69
+ Raspbianの構築手順を記載いたします。
70
+
71
+ OSは導入された前提で
72
+
73
+
74
+
75
+ rootユーザで以下を実施
76
+
77
+ ```ここに言語を入力
78
+
79
+ #apt-get install portaudio19-dev
80
+
81
+ #apt-get install python-dev (updateがかかります)
82
+
83
+ #pip install pyaudio
84
+
85
+ ```
86
+
87
+
88
+
89
+ home等に環境を作る
90
+
91
+ ```
92
+
93
+
94
+
95
+ # mkdir /home/test
96
+
97
+ ```
98
+
99
+
100
+
101
+ gitでソースを持ってくる(githubで公開しております)
102
+
103
+
104
+
105
+ ```
106
+
107
+ # git clone https://github.com/toshift/PyAudio.git
108
+
109
+ ```
110
+
111
+ cloneした環境で以下を実施 /home/test/Pyaudio とします。
112
+
113
+
114
+
115
+ ```
116
+
117
+ # Python pyaudio_blocking /home/test/Pyaudio/sound/00.wav
118
+
119
+ # Python pyaudio_blocking /home/test/Pyaudio/sound/01.wav
120
+
121
+ ```
122
+
123
+
124
+
125
+ →これでどちらかで異音がなります。
126
+
127
+ pyaudio_callbackでは発生しないです。
