A simple nyquist plugin for audacity to automagically convert a recorded IR signal through a dual led jack IR Transceiver into a playable one.
It can convert a recorded IR signal (using this method http://jumpjack.wordpress.com/2008/05/22/remote-control-2) into a playable IR signal in just one click, by automating the manual procedure described here: http://jumpjack.wordpress.com/2008/05/22/remote-control-3-editing-waveform.

Download the "[IR]Converter.ny" file and just move it into the "Plug-Ins" folder, in the Audacity installation dir.
- Start Audacity
- Plug your (trans)receiver into MICROPHONE input of your sound card
- Place your remote in front of the LEDs
- Start recording: stereo track, 44100 Hz, 16 or 32 bit.
- Press a button on remote
- Stop recording
- Open Audacity "Effect" menu and select "[IR] Converter"
- Select the channel (Left or Right) in which the square wave has been stored, press OK
- Plug your transmitter (or transreceiver) into AUDIO-OUT, point it to your remote controllable device and play the converted signal!
- The input signal MUST be stereo to generate a working IR signal!
- It may be necessary to ZOOM a lot into the waveform, both vertically and horizontally, to see the square waves, as the signal is very short (few milliseconds), and probably quite low.
v0.1:
- initial release
v0.2:
