9 // Sample code for reading a stereo buffer:
10 //
11 // bool isLeftConstant = (buffer->constant_mask & (1 << 0)) != 0;
12 // bool isRightConstant = (buffer->constant_mask & (1 << 1)) != 0;
13 //
14 // for (int i = 0; i < N; ++i) {
15 // float l = data32[0][isLeftConstant ? 0 : i];
16 // float r = data32[1][isRightConstant ? 0 : i];
17 // }
18 //
19 // Note: checking the constant mask is optional, and this implies that
20 // the buffer must be filled with the constant value.
21 // Rationale: if a buffer reader doesn't check the constant mask, then it may
22 // process garbage samples and in result, garbage samples may be transmitted
23 // to the audio interface with all the bad consequences it can have.
24 //
25 // The constant mask is a hint.
