示例1:
TEST (LowPassFilterTest, WorksOnRepetitiveWaves) {
// make two sine waves, but this time, several seconds long
unsigned int samples = frameRate * 5;
KeyFinder::AudioData a;
a.setChannels(1);
a.setFrameRate(frameRate);
a.addToSampleCount(samples);
for (unsigned int i = 0; i < samples; i++) {
float sample = 0.0;
sample += sine_wave(i, highFrequency, frameRate, magnitude); // high freq
sample += sine_wave(i, lowFrequency, frameRate, magnitude); // low freq
a.setSample(i, sample);
// ensure repetition of sine waves is perfect...
if (i >= frameRate) {
ASSERT_NEAR(a.getSample(i), a.getSample(i - frameRate), tolerance);
}
}
KeyFinder::LowPassFilter* lpf = new KeyFinder::LowPassFilter(filterOrder, frameRate, cornerFrequency, filterFFT);
KeyFinder::Workspace w;
lpf->filter(a, w);
delete lpf;
// test for lower wave only
for (unsigned int i = 0; i < samples; i++) {
float expected = sine_wave(i, lowFrequency, frameRate, magnitude);
ASSERT_NEAR(expected, a.getSample(i), tolerance);
}
}示例2:
TEST(AudioDataTest, SamplesBasic){
KeyFinder::AudioData a;
a.addToSampleCount(100);
ASSERT_EQ(100, a.getSampleCount());
// init values
for(int i=0; i<100; i++){
ASSERT_EQ(0.0, a.getSample(i));
}
a.setSample(0, 10.0);
ASSERT_EQ(10.0, a.getSample(0));
