The following C++ code example is a Windows application that displays a peak meter for the default rendering device: // Peakmeter.cpp - WinMain and dialog box functions
#Peakhour software software
In exclusive mode, the application and the audio hardware exchange audio data directly, bypassing the software peak meter (which always reports a peak value of 0.0). If a device lacks hardware peak meter, the peak meter is active in shared mode, but not in exclusive mode. If a device has a hardware peak meter, the peak meter is active both in shared mode and in exclusive mode. Otherwise, the interface implements the peak meter in software. If the audio endpoint device implements the peak meter in hardware, the IAudioMeterInformation interface uses the hardware peak meter. For example, if a PCM stream contains 16-bit samples, and the peak sample value during a particular metering period is -8914, then the absolute value recorded by the peak meter is 8914, and the normalized peak value reported by the IAudioMeterInformation interface is 8914/32768 = 0.272. The peak-meter values obtained from the methods in the IAudioMeterInformation interface are floating-point numbers in the normalized range from 0.0 to 1.0. For a capture device, the value retrieved from the peak meter represents the maximum sample value encountered in the input stream from the device. For a rendering device, the value retrieved from the peak meter represents the maximum sample value encountered in the output stream to the device during the preceding metering period. This interface represents a peak meter on an audio endpoint device. On fans to cool a room instead of an air conditioning unit.To support Windows applications that display peak meters, the EndpointVolume API includes an IAudioMeterInformation interface.
