| Summary: | The increasing market for mobile devices requires us to investigate the viability of writing computationally expensive digital signal processing applications for these devices. Modal Distribution was used to acquire a time-frequency representation to evaluate singing ability using a karaoke application. Pitch and tempo were both used as basis for grading. The trade-off between the time-frequency resolution and the execution time of the algorithm especially for devices with slower processors was studied to observe the optimal parameters for Modal Distribution. A resolution of 10 milliseconds for tempo and 31.25 Hz were thus obtained. |
