[PC] IR Converter - Audacity Plugin

Hi everyone,
I'm here to share with you a simple nyquist plugin for audacity that I wrote to automagically convert a recorded IR signal into a playable one.
IRConverterLogo.png
Its name is [IR] Converter and it should be really useful for the ones that have (bought or built) a dual led jack IR Transceiver (here for more info: http://wiki.samygo.tv/index.php5/Remote ... ransmitter or viewtopic.php?f=16&t=4353 or http://jumpjack.wordpress.com/2008/05/2 ... tor-just-1)

It can convert a recorded IR signal (using this method http://jumpjack.wordpress.com/2008/05/2 ... -control-2) into a playable IR signal in just one click, by automating the manual procedure described here http://jumpjack.wordpress.com/2008/05/2 ... g-waveform.

INSTALLATION
Download the attached zip archive, extract the "[IR]Converter.ny" file and just move it into the "Plug-Ins" folder, in the Audacity installation dir.

USAGE
Open Audacity and, after recording an IR signal using this method http://jumpjack.wordpress.com/2008/05/2 ... -control-2, go into the Audacity "Effect" menu and select "[IR] Converter".
In the plugin configuration dialog, you can select the channel (Left or Right) in which the square wave has been stored (read here for more info http://jumpjack.wordpress.com/2008/05/2 ... g-waveform).
Important: The input signal MUST be stereo to generate a working IR signal!

If you need help or have any suggestion, just write here ;)

Changelog

Refer to this page http://jumpjack.wordpress.com/2008/05/2 ... control-2/ and the following ones to a full tut.

SOME ADVICES
When recording, pay attention to the direction and the distance of the real remote (the one which is sending the ir code you want to record) from the recording leds:
The remote control led should very very close to the recording leds to let the mic catch the sent signal.
If your pointing the remote in the right way, you should see some square waves recorded, very similar to the one shown in the first post or in the page link I just gave you some lines above.
You could need to change the zoom level in Audacity to manage to see those waves.

If you cannot see any square wave:
  • Your remote control is not near enough to your recording leds.
  • There's something wrong in the way you built it.
If you can see those waves, but the wav generated by this plugin is not working:
  • The sender device volume is too low. Just raise it to the max.
  • Your ir-jack blaster is too far from your TV (or the device you are trying to control).
  • There's something wrong in the way you built it.

thanks for your replay,
can you make a video tut about convert IR code to wav with this plugin?

Hi, I successfully tried your procedure. Now I have a converted waveform which can be sent to a conditioner, but I need to send it by an Arduino card.
My question is: how can I convert the wav to a values sequence?
thank you.
