    P.S.

    An old Symbian series60 phone costs around 50$ and is easily programmable in Python to process incoming SMS; I can easily write the needed SW once I have the needed HW!

    You need to use an IR Sensor (QSE156) because the IR Receiver in your VCR demodulates the signal.

    no, the weird thing is that the FIRST graph is obtained connecting a simple IR LED (not an IC infrared rceiver) to audio card!

    Anyway I can't find in italian shops the required HW, so I need an alternate method to go on...

    I prepared a little tutorial about how to sample remote controls:
    http://www.hackint0sh.org/forum/showthread.php?t=41092

    I need a bit of help for the last part: once I have the waveform, how do I figure out the LIRC code?

    Once this iCouchPotatoe project will be finished, we'll need just a further step: a SW which turns the waveform in "soemthing" suitable to be emitted by the IR-dongle that is under design.

    Then, everybody who can afford a 0.50$ LED will be able to clone his remotes with an Iphone!

    Your system doesn't permit the Audio to IR reproduction without doing many manipulations.

    - Recording
    - Cleaning (blank noise begin/end)
    - Switching the mono sound to stereo
    - Inverting the right channel (180º)
    - Amplify
    - Normalize

    Also the success/result is not gonna be the same according to the sound-card specifications of the computer. (i did it before deciding to switch to a hardware solution)

    The IR to Audio Converter does everything by hardware, you just need to normalize the recorded audio file and save it as AIFF or WAV.

    Which system are you referring to? I only set up a system to SAMPLE remotes, not to "play" IR sounds.

    Could you please explain how to obtain a suitable audio track for your device using an audio program like Audacity?

    Let's suppose I properly record the remote control ouptut as a series of carrier pulses; should I just split the mono track into two stereo tracks and invert one of them, to obtain the right waveform?

    Or can I just play the sound, and the LED couple will do the phase inversion?

    Anyway my real problem is that my system clears up the carrier, leaving just "bits", so I need to recreate them. Does it exist any software which produces a waveform after accepting a carrier and a modulation signal as inputs?

    I prepared a full tutorial about how to build a simple receiver for your remote, sample its buttons and replicate them.
    All of this just using two IR LEDs and nothing more ;-)

    Hi, im not sure if this has been touched on but for a later version (prob v.3 ) would you consider changing the program from a Universal "Infrared" Remote Control program to a Fully Universal Remote Program by adding modular support other non IR remote control interfaces. For example VNC over wifi for computers (touchpad pro ish) and other devices like TiVo and PS3 (over blue tooth)?

    While I understand you may not wish to develop these features yourself would you consider using your application (and reputation) as a distribution system so that other remote control developers could submit extra features to a single universal remote project.

    The program could work by having one icon on springboard and opens to a customizable menu to select what device you wish to control. Other developers could submit specific control programs or IR sets which would be stored under the device name on the menu. It could work through a settings page similar to boss prefs where modules are turned on then the program downloads the ones you want and enables them. By installing only packages you need it will save on room and allow for uninstalls of remote sets as peoples setups change.

    What you are currently developing is an important part for a universal system, my recommendation in short is not to limit the project to an IR remote, rather aim for a universal remote that will utilise all the different communications methods available to the iPhone.

    Excuse my ignorance but aren’t most of these remote ‘codes’ already documented somewhere? I mean there are plenty of IR control programs out there for other devices which come with the profiles for all common TV brands etc built in.

    ie; Choose ‘sony’ - press ‘power’ - TV turns on…

    You're right.
    Indeed technics described in this thread are mostly for users of uncommon remotes, which can't find suitable configuration files for their devices: being able to just sample&replay a remote should allow anybody with an audio-capable handheld to use it as remote control clone.
