针对车载音响的声场校正精度低、效率低的问题,该文提出一种无重叠频带的自适应非对称并联图示均衡器校正方法。在车载音响声场动态变化情况下,该方法考虑了有效均衡范围和自适应增益,而不是经典方法中的固定均衡范围和人工给定的增益... 针对车载音响的声场校正精度低、效率低的问题,该文提出一种无重叠频带的自适应非对称并联图示均衡器校正方法。在车载音响声场动态变化情况下,该方法考虑了有效均衡范围和自适应增益,而不是经典方法中的固定均衡范围和人工给定的增益。通过对实测数据进行实验分析,所提方法比经典方法所用均衡滤波器个数平均减少大约20%,拟合目标增益更准确,校正后频谱曲线更平坦。 展开更多

This paper describes an audio digital signal-processing toolkit that the authors develop to supplement a lecture course on digital signal processing (DSP) taught at the department of Electrical and Electronics Engineering at the University of Rwanda. In engineering education, laboratory work is a very important component for a holistic learning experience. However, even though today there is an increasing availability of programmable DSP hardware that students can largely benefit from, many poorly endowed universities cannot afford a costly full-fledged DSP laboratory. To help remedy this problem, the authors have developed C#.NET toolkits, which can be used for real-time digital audio signal processing laboratory. These toolkits can be used with any managed languages, like Visual Basic, C#, F# and managed C++. They provide frequently used modules for digital audio processing such as filtering, equalization, spectrum analysis, audio playback, and sound effects. It is anticipated that by creating a flexible and reusable components, students will not only learn fundamentals of DSP but also get an insight into the practicability of what they have learned in the classroom. 展开更多
