C++ (Cpp) volume_decibel_to_level Beispiele

Beispiel #1

Datei: upnp_control.c Projekt: LeePorte/gmrender-resurrect

// Change volume variables from the given decibel. Quantize value according to
// our ranges.

	int volume_level = volume_decibel_to_level(raw_decibel);
	// Since we quantize it to the level, lets calculate the
	// actual level.
	float decibel = volume_level_to_decibel(volume_level);

	char volume[10];
	snprintf(volume, sizeof(volume), "%d", volume_level);

	fprintf(stderr, "Setting volume-db to %.2fdb == #%d\n",
