RC Tanks Australia Forum

Hey All

One of the great features of Asp is the ability to create your own sound sets and have custom sounds for your tank. There will be further posts both here on the forum and on the Asp Wiki page on how to do this in detail but first the Asp user will need to know how Asp deals with sounds.

First up Asp uses wave files (.wav) at 44.1 kHz and 16 bit. This is the format for CD files and is probably the most common wav format out there. Asp does not use poorer quality 22000 kHz like some other sound options available. Files can be in stereo or mono. HOWEVER, the Juno board contains a MONO amp only and hence it is recommended that smaller MONO files be used. It would be possible to modify your Juno board to send stereo files to a stereo amp but realistically the benefit of this would be minimal if at all.

The sound files are then stored in the root directory of one of two sound cards. These cards are then inserted into the sound modules on Juno. In general Module A contains the engine sounds while Module B contains the turret, weapons and music/fx sounds. Although this is not the most streamlined of setups it does provide for a duophonic CD quality sound option at a very reasonable price point.

Asp uses a LOT of sounds - at present there are 102 sounds on Module B and 76 sounds on Module A. Hence it is important to have a descriptive method to naming of the sound files. RCTA has a naming convention but the user can come up with their own convention if they wish. The convention used here is as follows:

001_A_T-34_EngineStart1.wav

001: File number *VERY IMPORTANT*
A: Module on which the file is placed
T-34: Type of tank the sound is for (Gen=general for all tanks, User=personal sounds)
EngineStart1: Description of the sound

With all this information it is easy to tell where a sound needs to be placed.

****************
MOST IMPORTANT
****************
Please read this part as I suspect that this part if not understood will cause dramas with sound set customisation.
Although the files are ordered 001, 002, 003, etc this is primarily for your benefit and for the computer you are using to sort the files in order. When the files are placed onto the SD card - the sound module when ordered to play sound number 1 DOES NOT LOOK AT THE FILE NAME for 001. Rather the sound module looks for the file FIRST FILE CREATED on the SD Card and plays that as sound #1.

Consequently, lets say there are only 2 sounds 001.wav and 002.wav. When it is time to transfer them to your SD Card you must transfer 001.wav first and then 002.wav. If 002.wav is transferred first the sound module will play 002.wav when it is instructed to play sound number 1.

Well why bother naming them in the first place I hear you say? Files are named with 001 and so on at the start so that your computer can sort them in name order. To edit your sounds you should transfer the ALL the sounds from your SD Card to your computer and edit them there. Once the files have been edited open your file manager program and sort them in name order. Press control "A" to select all and then control "C" to copy all. Go to the root directory of your SD card and press control "V" to paste all the files back to the SD card. Typically I will delete all the files on the SD Card first before pasting the edited sounds.

Do not edit files directly on the SD card nor transfer individual sounds to the SD card.

Once your files are back on the SD Card you can check all is good by sorting the files in your file manager program (Windows Explorer for PC users) according to "Date Created". The list of sounds should then appear in numerical order as follows:
001_A_A7V_Startup1.wav
002_A_A7V_Startup1.wav
003_A_A7V_Startup1.wav
004_A_A7V_Startup1.wav
005_A_A7V_Shutdwn1.wav
006_A_A7V_Shutdwn1.wav
007_A_A7V_Shutdwn1.wav
008_A_A7V_Shutdwn1.wav
009_A_A7V_MotionStp.wav
010_A_A7V_Idle.wav
etc...

Well that is the important info for this post and the most important thing you will need to know when changing or editing sound sets.

Cheers

Hiya Kevin,

Is there a limit to the size of micro SD card that can be used, for ASP users to store their sounds on.

Andy

HI Andy

No size limit - But I would not suggest getting 32GB cards and storing everything on there. 1 or 2 GB cards are dirt cheap the method I use is to have a pair of these smaller cards for each Tank type. They you can easily swap sound sets with out using a computer.

Cheers
KG

Hi Kevin,

Perfect !!! ....just what I was thinking a small SD card for each tank

Thanks
Andy
