Stereo version

[thanks-for-your-help]

Hello,

I try to modify this post for doing a stereo version.

I modify the wav header as :

header[22] = 0x02; // stereo
header[28] = 0x10; // Byte/sec = (44100x16x2)/8 = 176400 STEREO
header[29] = 0xB1;
header[30] = 0x02;
header[31] = 0x00;
header[32] = 0x04; // 16bit stereo

I modify too
const int waveDataSize = record_time * 176400; // (44100x16x2)/8 = 176400

The generated file is indeed stereo. There is audio on both channels. The waveform looks identical. The speed is twice as fast. I think it must miss the bytes of the second channel.

Could you help me with some code ?

Could you explain theses two lines please :

const int numCommunicationData = 8000; // Why 8000 ?
const int numPartWavData = numCommunicationData/4; // Why ?

Best regards
