Example ¶
ExampleDenoiseProcessor_Process 使用示例
// 创建处理器
processor, _ := NewDenoiseProcessor(&DenoiseConfig{
AECEnable: true,
AGCEnable: true,
SampleRate: 16000,
Channels: 1,
BitsPerSample: 16,
})
defer processor.Close()
// 生成测试音频
testAudio := generateTestAudio(16000, 100, 1000, 0.2)
// 处理
denoised, _ := processor.Process(testAudio)
// 计算效果
noisyRMS := calculateRMS(testAudio)
denoisedRMS := calculateRMS(denoised)
reduction := (1 - denoisedRMS/noisyRMS) * 100
fmt.Printf("Noisy RMS: %.4f\n", noisyRMS)
fmt.Printf("Denoised RMS: %.4f\n", denoisedRMS)
fmt.Printf("Noise reduction: %.2f%%\n", reduction)
func (*DenoiseProcessor) ProcessInPlace ¶
