Soundboard
Play stored sounds over RF
What it does
SimpleYou can save little sound clips on the memory card, and this app will play them out as a radio signal instead of using the live microphone. It's like a jukebox for the Audio transmitter.
Because the clips are exactly the same every time, it's handy for repeatable tests — you can send the identical sound again and again to check how a receiver behaves.
How it works
SimpleInstead of a microphone, the app reads a sound file from the memory card and feeds it to the transmitter, painting that recorded sound onto the radio wave. Since it's a file, it plays the same way every single time.
How to use it, step by step
Simple- Put sound files on the memory card.
- Open 'Soundboard' and pick a clip.
- Choose an allowed channel.
- Play it and listen on another radio.
Examples
Transmit a fixed WAV tone sequence to measure a receiver's response consistently.
Send a known tone and confirm your receiver shows the expected FM deviation.
Play the same clip on AM then FM to compare the receiver's audio.
Tips & things to try
- Fixed files = repeatable tests; that's the whole advantage over the live mic.
- Keep WAVs at a sensible sample rate/level to avoid distortion.
- Use a dummy load or your own receiver for anything hands-on.
