    Re: Open source timing software.

    Thanks Contrate_Wheel for help.

    And thanks for this open source programme.



    As you suggested, I recorded about a minute with Audacity, and I am trying to post it. But its an .aup file. This kind of file are not allowed to upload on this forum.

    How can I send you the recording?

    Re: Open source timing software.

    Does this work on Windows XP?
    Wife: Don't you have enough watches?
    Me: Don't you have enough earrings?
    Wife: So, you're saying that watches are jewelry for Men?
    Me: That's exactly what I'm saying.
    Wife: Let's go shopping.

    And that's how I got my last watch...

    I tried TG, on my XP laptop, and didn’t work. I got a very weak and inconsistent signal, so impossible to use it.

    I guess, it didn’t work on my XP laptop because my soundcard was very basic.


    For those of us, who got weak signal. I found a open source programme called: Guitarix, Virtual guitar amplifier.


    I was wondering if this could fix the problem of TG low signal. If this programme some how could feed TG.


    What do you think?

    Re: Open source timing software.

    Downloaded today Win binaries, works out of the box at Win10 x64... Really great stuff. Tried with builtin mic but it had too much noise. Then I tried with my phone's headphone/mic at it worked nicely. Since I'm away from home, I have only one watch to test, without calibration...
    But...
    When we speak about calibration, is it possible to use some prerecorded sample audio file from accurate source, which can be played on some MP3 or similar, so we can get proper calibration sequence instead of using quartz clocks?
    Just a bare idea, but sort of could be interesting...

    I think that would require the MP3 to play through the same soundcard input as the pickup microphone - it's probably easier to just use a cheap quartz watch...

    this might add not less than another imprecision or even two, if you replay the sounds with a diffent device than recorded.

    Probably wouldn't work, since then you're using an uncalibrated DAC to play the file, so you'd have no idea if your resulting audio actually ends up faster or slower than it should be.

    If you ran it through the same sound card that you're recording from... chances are it's using the same oscillator time reference for its DAC (for playback) and ADC (for recording), so there's no way actually tell if your sound card is running fast or slow if you do it that way.

    Nevermind that whatever you recorded the sample audio file had to have a properly calibrated ADC to begin with...
