  • Fun multitouch audio app

    , BitFlipper wrote

    I don't think this is an issue with managed vs native. Games are usually much more CPU intensive and they are pretty responsive. The only time managed vs native comes into play is when you need to do custom DSP that is too slow with managed code.

    that's just it... almost anything interesting you'd want to do is "custom dsp". xna can do mixing, volume, panning, maybe a couple different types of filters, but i couldn't find any help with building a virtual synth, spectral shaping, custom effects or even an event model that supports midi. midi is 25+ years old! the "close to the metal" game loop and dsp in xna supports gaming and gaming only.

    since native code is not supported on wp7, i'm afraid we'll never see the type of compelling creative apps on it like the iphone. on my iphone i have nanostudio, sunvox, and a 4-track recorder... arguably more power than the beetles had, in my pocket.

  • Fun multitouch audio app

    i think latency is going to be a big problem if you want to do any real-time audio apps, but it could work for offline beatbox/pattern arrangement type apps. android also suffers from this... it's the nature of garbage collected managed code. this is one area where iphone has a considerable lead... the next iOS is actually including native midi i/o support!

    i'm working on a quirky pattern-based sequencer type app now that uses nAudio library. i'd love to get it to work on wp7, but not sure if it will.

  • Display a System Control Panel in Win7 64bit

    yeah, but they changed the whole way to call these things 3 times between xp, vista and now windows 7. i'm reading more about it now... probably posted here to soon, but i thought it would be a quicky that someone already came across.

  • Display a System Control Panel in Win7 64bit


    in xp i could shell and run the appropriate .cpl applet with


    but it fails in windows 7 (64 bit). i'm having a hard time finding any documented way to do this. anyone have an idea? specifically i'm trying to run the sound/audio settings.

  • Capturing Voice Through Web App Strategy

    thank you. java seems like a viable option, but we're not a java shop. would anything need to be installed on the server? sorry if that seems like a dumb question but i admittedly don't know much about java development besides a class i took a long time ago. it might take some convincing but if its the path of least resistance, then an embedded java app that talks to a web service may be worth a shot.

  • Capturing Voice Through Web App Strategy


    We're fleshing out the technical feasibility of a project that would involve remote sites recording voice responses from various stimuli and sending that captured stream to our server.

    At our sites we can guarantee:

    1) consistent hardware ("gamer-style" plug and play usb headset)
    2) java vm (current)
    3) flash >= 9
    4) stations running >= xp pro
    5) Internet Explorer >= 7.0

    We would need full duplex recording... in other words, a stimuli played with a timer going while recording only the voice response (think continuous translation services). The recorded stream can be anywhere between 5 -60 seconds. The playback stream would be the same length. Quality is important as a human will need to understand what was recorded at a later time.

    What are my options? Could an actixe-x control be used? The main problem here I'd imagine would be that the stream would have to saved locally, then uploaded after the fact, which could be a problem.

    VOIP server might be the way to go?? Any thoughts/experiences would be greatly appreciated.

  • Missing Vista Basic Install Media

    many moons ago, i bought an acer laptop that came with vista basic with the intention of wiping it and installing my system builder xp. i did so and all was well.

    i just bought a new laptop that came with win 7, but i'd like to restore the old laptop and donate it, but i was a moron and didn't create a restore disk. i think the original hard-drive might have come with a restore partition but it has since been wiped clean.

    i have a valid serial number for vista basic on the bottom of the laptop but i can't find any install media to use. does anyone have a work around? seems silly i can't get to an installer iso for a product i own.

    i'd rather not pay for replacement media from acer. i would love to be able to just download an iso and install from that.

  • New project: Should it be WPF or WinForms?

    sorry to resurrect this old thread but i was wondering how this project is coming along.

    i just came across the naudio library and before getting into it too much was wondering if anyone had other recommendations for dsp/audio/midi in .net, preferably open source.

    we desperately need a proper audio and dsp library. i've looked into xna and direct x but everything seems geared towards gaming. i also just read about this project to create wrappers for PureData, but no one is doing it for C# yet, but they have it for Obj-C and java. A wrapper for PD in theory would allow the engine to be embedded anywhere that could run native code but interact with it using whatever language you choose. There's currently a java wrapper so it probably wouldn't be too much of a chore to take on. hmm....

  • Microsoft.​Office.​Interop.x

    hrmm... so i have an .xlsx file on my desktop. if i change the extension to .zip and open it up, i see the xml internals with relationships. is it naive to think if i could write these xml/rels as text, i could recreate the file from scratch?

  • Microsoft.​Office.​Interop.x

    @phreaks:what exactly are you trying to do in excel? if you're just reading data out then go with ado.net and treat it as a datasource.

    for simple things i sometimes take advantage of the fact that excel (and word) can read/open html files. no interop needed for quick simple tasks of displaying grids of data with some lite formatting. just write the html file out to the browser with an excel extension header.

    if you're diggin deeper with pivots and formulas, as far as i know interop is the way to go with office installed on the server. i think there are other 3rd party libs out there as well, but i have yet to have the need (would love to also hear recommondations though).
