sound alert

[velocity]

Don't know if this expected behavior but thought I would mention it.

When importing indicators from 6.5 to 7, if you have a sound alert using

PlaySound(@"C:\Program Files\NinjaTrader 6.5\sounds\Alert1.wav");

you better change it to

PlaySound(@"C:\Program Files\NinjaTrader 7\sounds\Alert1.wav");

I would have expected that it would not matter where the wav file is located, however NT7 only recognizes the path with NinjaTrader 7.

hmmmm?

Velocity,

I don't believe you need the NinjaTrader path in there at all.

It defaults to the C:\Program Files\NinjaTrader x\sounds\ directory

I always just use PlaySound("Alert1.wav"); that will use the proper directory.

Thanks for the tip.

I use indicators with customized sound alerts. So I copied the .wav files from the NT 6.5. to the NT 7 sounds directory.

When using the indicators with NT 7, I do not get any sound alerts, but the indicator throws an exception, as can be seen in the trace file:

Cbi.AlertCollection.ProcessEventArgsInThreadContex t, exception caught: The Sound-API only supports PCM wave files.

What is this again, and why have specs changed with respect to NT 6.5.?

For those, who have the same problem: The Windows Audio Recorder allows to convert all types of WAV files to WAV/PCM files. After conversion the WAV files used for NT 6.5. can also be used for NT 7!

Harry, thanks for figuring that out.

Can the NT7 Sound API be modified in a way that it reads the same .WAV files as NT 6.5.? There might quite a number of users with their soundfiles no longer working when switching form NT 6.5 to NT 7.

Just in case that they do not find this thread.

Unfortunately not.

Hmm ... I just checlked. I would not find a reference for "Windows Audio Recorder" on my Win7 64bit machine. There is a "Sound recorder" which would allow to record but not to convert existing sound files. Am I missing something?

Thanks

Hi Dierk,

this another present from Microsoft to make their customers happy. :D

Windows XP Professional: Audiorecorder allows to convert audio files. The audiorecorder will save any open file in 12 different file formats, each with a large variety of further options.

Windows Vista: Audiorecorder cannot convert sound files.

I do not own a Win7 64bit machine, but I imagine that Microsoft has maintained this new feature of their audiorecorder.

Thanks for your feedback. Where exactly in XP would I find that audio recorder?

[Harry]

Basically you would need to convert WAV/MPEG to WAV/PCM files. If Windows Vista and Windows 7 do not come with a conversion tool, you could download some freeware. I just tested a tool called free audio converter, and it was easy to convert my WAV/MPEG files. It just annoyed me a little, because everytime I used it, it wanted to install a toolbar....

Excellent. Thanks

Programme -> Zubehör -> Unterhaltungsmedien -> Audiorecorder (sorry my Windows is not in English)

[Harry]

I am sure there are other tools as well. This was just the first one I stumbled upon...
