![]() □ I normally spend most of my development hours coding for Android, using Java in fact, my first book, OpenGL ES 2 for Android: A Quick-Start Guide, is a beginner’s guide to OpenGL that focuses on Android and Java. Some of you might be curious about why I am so interested in this subject. I’ll be sharing both the code and the results with you today. With this new code, I refactored the code into a new benchmark with test audio data, so that I could compare the different implementations and verify their output. ![]() This result brought more attention to the post than I was expecting some of you were also curious about RenderScript, and I’m pleased to say that Jean-Luc Brouillet, a member of Google’s RenderScript team, got in touch with me and generously volunteered an implementation of the DSP code in RenderScript. In my previous post on this topic, A performance comparison between Java and C on the Nexus 5, I compared the performance of an audio low-pass filter in Java and C. The results were clear: The C version outperformed, and by a significant amount. ![]()
