Real Time Audio Analysis In Linux

I'm wondering what is the recommended audio library to use? I'm attempting to make a small program that will aid in tuning instruments. (Piano, Guitar, etc.). I've read about ALSA & Marsyas audio libraries. I'm thinking the idea is to sample data from microphone, do analysis on chunks of 5-10ms (from what I've read). Then perform a FF...

Real time system concept proof idea to be done in 3 months

I'm taking an introductory course about real time systems design, but any implementation. I would like to build something that let me understand better what I'll learn in theory, but since I have never done any real time system I can't estimate how long will take any project. It would be a concept proof project, or something like that, ...

Ext JS - How to update data source update every minute with deltas ?

Looking for a reference implementation. Haven't tried LiveGrid - though tilting towards that implementation. Before I migrate, I was wondering if anyone could point me in a better direction. ...

Is there any sort of API that'll give me real-time(ish) MLB stats?

I think it'd be fun to build a little mini-fantasy baseball game, but after a bit of Googling, I'm getting the impression that there's no easy and reasonably-priced (or free!) way to get that data. Have any of you done something like this? Should I be thinking about screen-scraping? ...

Available Game network protocol definition languages and code generation

I've been looking for a good general purpose binary network protocol definition framework to provide a way to write real-time game servers and clients (think World Of Warcraft or Quake III) in multiple languages (e.g. Java backend server and iPhone front-end client written in Objective-C and Cocoa). I want to support Java Flash clients...

How do I check my appplication's cpu usage (inside the app of course)?

Duplicate: http://stackoverflow.com/questions/278071/how-to-get-the-cpu-usage-c I have an application that is displaying stuff in real time. However, when the feed is giving too much info, my app will take up 100% of CPU. Other stuff is running too so I don't want that to happen. I know I can avoid this by storing the incoming data in...

Querying real time data from an SQL database sudden latency problem.

We are testing an application that is supposed to display real time data for multiple users on a 1 second basis. New data of 128 rows is inserted each one second by the server application into an SQL datatbase then it has to be queried by all users along with another old referential 128 rows. We tested the query time and it didn't exce...

Simplifying algorithm testing for researchers.

I work in a group that does a large mix of research development and full shipping code. Half the time I develop processes that run on our real time system ( somewhere between soft real-time & hard real-time, medium real-time? ) The other half I write or optimize processes for our researchers who don't necessarily care about the code a...

Alternatives to rrdtool?

I'm looking for an alternative to the rrdtool It need to be fast, reliable, able to handle large amounts of data and have a Java interface. One possibilty I'm investigating is KDB+ Any other ideas? ...

What can I use for real-time plotting/graphing in C++?

I am looking for a C++ library or component which would ideally be cross-platform, but will first only be needed for Win32. The requirements are: one to 10 updates per second good documentation and samples easy to use cross platform (optional) Basically we have some data derived from financial market data feeds and we do some calcul...

Real time code coverage viewer tool for inspecting live Java apps?

I've been looking for a code coverage viewer aimed at inspecting live Java applications, mostly webapps running inside an application container like Tomcat. Sure, there are a number of decent tools for getting automatic reports of unit test coverage, but my aim is more like learning in real time what an unfamiliar Java app does e.g. on a...

Java Realtime Performance

I'm working with Java project that requires very advanced manipulations of images. In fact, I'm doing most of the manipulation using OpenCV, and I'm using JNI to wrap around the OpenCV functions that I need. I am extremely satisfied with the performance OpenCV gives, the people who wrote the OpenCV code deserve great great credit for the...

C# Charting - Reasonble Large Data Set and Real-time

I'm looking for a C# WinForms charting component, either commercial or open source, that can handle relatively large data sets and be reasonable scalable with regards to chart rendering and updates. The number of data sets to be displayed would be around 30. There would be between 15 and 20 updates per second for each data set. A line ch...

Real time process communication in game development

If you make a game architecture that splits up system components (IE, rendering, physics, logic, input, scripting, etc) into different threads, how do you handle cases where real-time communication is necessary? For example, if a script wants to draw a box on the screen, it would ideally do this when the rendering component issues a "Fr...

Storing Real Time data into 1000 files

I have a program that receives real time data on 1000 topics. It receives -- on average -- 5000 messages per second. Each message consists of a two strings, a topic, and a message value. I'd like to save these strings along with a timestamp indicating the message arrival time. I'm using 32 bit Windows XP on 'Core 2' hardware and progr...

Is there an off-the-shelf clock synchronization solution for Java?

We have a large high-performance software system which consists of multiple interacting Java processes (not EJBs). Each process can be on the same machine or on a different machine. Certain events are generated in one process, and are then propagated in different ways to other processes for further processing and so on. For benchmarki...

How to do full duplex programming with .NET?

After seeing the Google Wave demos, I thought of incorporating "real-time" capabilities into my web application, where one user will be able to see text another user is typing in as it happens... Besides the soft real-time capabilities built into .NET based on how the framework handles threads... Is there anything else I would need? I...

SQL Compact To SQL Express Real-Time Merging/Syncing

I have an application that currently uses SQL Compact Edition as its database for capturing realtime data. Some of my users would like to write their own applications to query and report against this data while it's being captured by my application. However, SQL Compact edition runs in-process with my application and therefore does not...
