Normalize FFT magnitude to imitate WMP

由 孤街浪徒 提交于 2019-11-29 09:41:42
问题 So, I've been working on a little visualizer for sound files, just for fun. I basically wanted to imitate the "Scope" and "Ocean Mist" visualizers in Windows Media Player. Scope was easy enough, but I'm having problems with Ocean Mist. I'm pretty sure that it is some kind of frequency spectrum, but when I do an FFT on my waveform data, I'm not getting the data that corresponds to what Ocean Mist displays. The spectrum actually looks correct, so I knew there was nothing wrong with the FFT. I'm

I wrote a little graph visualizer class: public void simpleGraph(SparseMultigraph<Vertex,SEdge> graph, String name) { Layout<Vertex, SEdge> layout = new ISOMLayout(graph); layout.setSize(new Dimension(800,800)); BasicVisualizationServer<Vertex, SEdge> vv = new BasicVisualizationServer<Vertex, SEdge>(layout); vv.setPreferredSize(new Dimension(850,850)); //Sets the viewing area size JFrame frame = new JFrame(name); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.getContentPane().add(vv); frame.pack(); frame.setVisible(true); } How can I add labels for vertices and edges?

Visual Studio: Dataset and DataTable Visualizer not working in watch window

由 不打扰是莪最后的温柔 提交于 2019-11-28 04:44:57
问题 I have just installed visual studio 2005 service pack 1 on a Windows 7 64 bit machine. Everything appears to work fine and I am able to run my project without any errors. However, when I am in debug mode I have noticed a problem with the "Watch" window for DataTables and DataSets. I have a DataTable named dt and I enter it in the watch window. No magnifying glass appears to open the visualizer and I get the following error in the value column: 0x000000001d438c90 { KEY_XMLSCHEMA="XmlSchema"

HTML5 Audio Visualizer? [closed]

由 笑着哭i 提交于 2019-11-28 03:42:07
Is there such a player? I'm looking into making one purely out of JavaScript. Something like http://www.nihilogic.dk/labs/pocket_full_of_html5/ but randomly all mashed together? What are your thoughts? 2 years later and a solution is found :) https://github.com/jsantell/dancer.js I also stumbled upon a website which uses the audio API and three.js to create pretty nice looking visualizations: http://do.adive.in/music/ Over 3 years later and we have this: http://codepen.io/soulwire/pen/Dscga . I believe the experimental Firefox Audio API is currently the only way you can do this in HTML

Android Visualizer implementation crash

I am trying to implement the Android Visualizer class. I have looked up other trouble threads but I am still getting a fatal error. This all looks to me like it should work correctly, for whatever reason the AVD keeps on crashing. First off, I am using the permissions: <uses-permission android:name="android.permission.RECORD_AUDIO" /> <uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS"/> Here is my logcat: 12-21 15:10:46.983: D/dalvikvm(642): Not late-enabling CheckJNI (already on) 12-21 15:10:48.823: D/MediaPlayer(642): Couldn't open file on client side, trying server

How to write a custom native visualizer DLL for Visual Studio 2012 debugger?

由 女生的网名这么多〃 提交于 2019-11-27 00:23:14
问题 What is needed to write a custom native visualizer DLL in C++ for Visual Studio 2012 debugger? I want to display a value that can only be calculated from a class/struct on-demand hence a native visualizer DLL is required. Visual Studio 2012 uses a new method for implementing native visualizers called Natvis. As of this time, there is very little correct information on Natvis and especially on using Natvis to call a visualizer DLL. The DLL will calculate a display string based on class/struct

DataTable visualizer disappeared from my Visual Studio

由 心不动则不痛 提交于 2019-11-26 18:33:00
问题 A while ago I noticed I don't have a magnifying-glass next to my datatables. I used to have it, and somehow, sometime, it disappeared... Has anyone seen this happen? Do you know how to help me view my datatables again? Update: I'm still clueless about this. Could anyone point me in some direction, where should I even start looking for an answer? Thanks a lot. Update: I changed to a new computer, and still the same problem. But I pinpointed it to being only in Visual Studio 2005. On Visual
