to quickly view your tty devices (arduino is also a tty), use in the terminal:

dmesg | grep tty

grtz.

Anything new with the sound system?

Good tip Danny. thanks.
I see you started the build thread for the new version of the Full Arduino control system. Between that radio project and this sound system, you guys are going to force me to build a boat!

Hello HD,

Nothing new with the sound system. We are moving into sailing season now, most of us will be busy with that . Also, I will soon start construction of a new radio system using Danny's plans. After this season, I am thinking about a new version for users who want something very simple and easy to use. The interface will be any smart phone with no hardware hacking needed. In the boat will be the sound system taking commands directly from the smart phone. It will be simple and not interface to the receiver, so it won't have the throttle following or switching features, just the sounds. The user will push on-screen buttons on the smart phone to start and stop the soundfx. Similar to the way it's done on model rr controllers. It's all conjecture right now, and depends on:
  1. what the users want and if I get a decent amount of interest
  2. how much range we can get in an ad-hoc wireless network between the smart phone and the boat.

That last item will require some testing to make sure the range is acceptable.

Hello guys,

Now I am able to make sound with RASPBERRY!
I start to costumize the system.
Just now I have bell sound,Tughorn sound,Sirene sound and so...
I try to change the engine sound from a diesel engine to a gas turbine engine. For this I make the 12 archives with Audacity software. Until now it start to play, but after that stop.
I think there is some mistake, and I hope to find it.
Best Regards for all

Great, Iscold!

If you need help with the gas turbine files, post them here and I will take a look at them.

Gas Turbine Sound

Blutho,

Here are the 12 archives for gasturbine.
I compare the 12 archives for diesel engines with Audacity, and can not see any comand diference between then to change the rotation, but I can listen the diference.
I found on menu Audacity on top rigth side one comand to change the recorder velocity. But the velocity only change if you hit the green arrow near this menu.If you hit the green arrow on main menu nothing change. I am using version 2.0.5.
Then, what I do. For each archive I change the cursor on this menu and export the sound for the archive.
I will be gratefull if you can help me.

Regards

Hi Iscold,

These will work. I need to know if this is the sound you want to use for the HIGH rpm or the LOW rpm, then I can modify from there and create the rest of the series.

Yes, very possible.

What I am asking is this: should I use the sample you posted as the low rotation or the high rotation? Once I know that, it will become my starting point and I can modify from there.

Hi Iscold,

Here are the converted Gas Turbine files. Here's how you can test them:
  • Unzip the files and copy them to the "data" directory
  • From a terminal, run mnuSoundfx.py, it's a test program that lets you listen to and test the soundfx files
  • You will see something like this on the screen:
DEBUG:root:Welcome to the Hybrid Serial Soundsystem!

Enter command value:


Enter some command values (one at a time), like these:
21128 (Start Engine, runs for only 6 secs)
11000 (Engine rpm 1)
11025 (Engine rpm 2)
11050 (Engine rpm 3)
11075 (Engine rpm 4)
11100 (Engine rpm 5)
11150 (Engine rpm 6)
11175 (Engine rpm 7)
11200 (Engine rpm 8)
11225 (Engine rpm 9)
11250 (Engine rpm 10)
21032 (Start Ambient Sounds)
21016 (Start Crew Sounds)
21532 (Stop Ambient Sounds)
21516 (Stop Crew Sounds)

Then you can try reducing the throttles (11250 - 11000)
And finally, enter 99999 to exit the program

All the other command codes are listed in the file: pin_assignments.txt

I left the soundfx files in stereo format, as they weren't too large. But if they are loading to slowly for you, you can convert them to mono format in Audacity like this:

Menu Tracks -> Stereo Track to Mono


Enjoy,
blutoh
