Using different wav files

October 20th, 2010, 10:24 AM

I am using the label ray line alerts indicator. The alert4.wav is coded in the script. Is there a way to change the wav so that I can use different sounds for different contracts?

Your would need to change the indicator code to append the instrument name to the end of the wav file, for instance.

Post the code and someone can do it most likely.

you can use System.Speech of the .net framework. there has been works in these lines here at nexusfi.com (formerly BMT). search a bit you will get a solution.

Let's Teach NinjaTrader how to talk

Windows has text to speech capability that can be used by NinjaTrader. That means that instead of having a bunch of indicators that play back humorous but meaningless and confusing .wav files, your indicators can recite text that can be controlled programatically …

Mike,
Here is the code.

I don't know what this indicator is doing, but just change alertFileName value in OnBarUpdate():

Code

                            
...

        /// </summary>

        protected override void OnBarUpdate()

        {

            int j ;

            String beginMessage = Instrument.FullName + " - Ray Line Price Triggered on " ;



            alertFileName=Instrument.MasterInstrument.Name.ToString()+".wav";

    

            

            // Determine the Period Value

            switch ( BarsPeriod.Id )

...

and create one .wav for each instrument (TF.wav, YM.wav, ...).
Not tested.

Sam,
Thank you. I have no experience writing code.
So were it says ".wav" I replace it with YM.wav? Where do I put the sound file named YM?

What about the other section in red and in " "? Do I need to replace that with anything?

With NT7 (not sure about 6.5) it will look for unqualified wav files in the default sounds directory, which is c:\\Program Files\Ninja Trader 7\Sounds.

So you can use "*.wav" in that code where * indicates the actual file name.

If your wav files are somewhere else, you would need to add the whole path.

If you want to play around first, custom sound file triple_klaxon.wav is attached. Copy it to the directory mentioned above and then substitute the filename "triple_klaxon.wav" in your indicator to see how it works.

As you become more comfortable with using custom wav files, Google "ATT Text To Speech" to generate fixed, spoken phrases, and "Audicity" to edit wav files. The second attachment was generated by the ATT app and is a good example of a fixed, spoken phrase. Download them and play them with Windows Media Player to hear what they sound like.

You can also overwrite the defaults to enhance the user experience.

Thank you. I was going to use ATT sounds. I just need to make sure now that I do not ruin the code. So all is needed is to add the wav name. Nothing else to change on code?

I have installed that file now. Essentially you do not need to do any thing, because you can select the wave file via indicator dialogue. If you apply that indicator to an ES chart, simply type the name of the sound file that you want to use. For 6E just type in the name of another soundfile.

Ninjatrader 7.0 cannot handle all types of .wav files, MPEG format needs to be converted to PCM with an audio recorder. There is no similar problem with NinjaTrader 6.5 .
