I just rechecked. Nothing.
VolUp and VolDown don't work with the generated wavs on an iPad  |

Hmm ok I found the option, I don't see the phase inversion flag for stereo waveforms. You should add one. |
The "stereo" signal comes with the channels in opposite phases. (As can be read in the documentation or the popup help.) I do not plan on adding an option to generate two identical channels, since it would be useless. |

Yep. my bad. 2 identical channels = mono. |

|
|
Hello,
I'm a newbie when I comes to IR but I have created a dual IR transmitter connected to my Iphone. It works fine with apps that transmit signals to the home-made IR unit.
However, I want to create a WAV file so I can wake up to my TV from my Iphone (Iphone can be used to wakeup to music or any audio file).
So I thought I would just plug in my iphone headphone jack to my PC. I was able to record the file. But when I play it back through the Iphone (or PC) with the home-made IR attached, nothing happens.
I assume the sound is not clean. I've spent hours make sure that the WAV file was fine, using Audacity. I even equalized the file so I reflect a digital square wave instead of analog. But nothing works. I'm pulling what ever hair I have left out trying to get this work.
What am I doing wrong? How do I generate a POWER ON wave file for my Vizio TV? |

Thanks so much. I'll give it a try when I get home.
I want to learn how this is done. What software do you use to produce these wav files and why my recordings always fail with the techniques I use. |

I used an obscure feature of IRScope to create your wav. I've only done this once before, but I ended up telling that user off, so of course I never got any feedback. So I would really like to know if this worked or not.
I think you would want to do this via IRPMaster, and java script. I'd like to know how to do that too. Perhaps Barf will enlighten us. |

@Vicky: Feedback on your wave file: It is a 48k, 16bit, 2-channen anti-phase ("stereo") file, containing the claimed signal. Most remarkably, it ends with approximately 9 seconds(!) of silence. This is clearly suboptimal. (How I analyzed the wave file: Importing in IrMaster.)
IrMaster (that is without the "p") can generate a wave file like this (not the 9 seconds of silence however  ), with some additional options: Make sure that the export option is enabled (Options -> Enable Componenets -> Enable export pane) Just select the export pane within the IR protocols pane, select nec1 as protocol, set D=4 and F=8, press "Export". Done!
You do now want to know how to do this from the command line or from Java. Period. BTW, Javascript has not much in common with Java. |

Okay Barf,
HOW did you import it into IRMaster?

I thought you were doing this with IRPMaster with Achin. . . .
And yes I would like to know how to do this. It is not crucial for me to do, but it would be nice to know how. If I know how, I can recommend it.

Thanks for that, I had IRScope set for what I normally do, 9000 units of listening for capturing keys, forgot to cut that down to 500 units for a single capture.
The file has been reduced in size and time.

Doh! This really is simple!

The second one works great.
So now I'm curious.
A few apps in the iTunes store allow for learning TV remote options. I can take any remote and point it a IR receiver diode and the app reproduces the sound/signal. All within the that little IOS app.
How are they doing that? |

Also, I need to convert this to MP3 to work with Alarm clock apps. Converting it to MP3 caused it not to work. I used Audacity and exported it as 128 kbps / stereo output. Playing around with the limited settings did not produce the desired results. |
