General & Product Questions
What is a radio sound pack?
A sound pack is a collection of high-quality audio files (WAV format) designed to replace or expand the default system voice prompts on radio transmitters running EdgeTX or OpenTX. They provide voice callouts for flight modes, switch positions, telemetry warnings, timers, and arming statuses.
Do these sound packs work with EdgeTX and OpenTX?
Yes! All of our sound packs are formatted specifically for EdgeTX and OpenTX file paths and audio codecs.
Are the voice packs instantly available after purchase?
Yes. As soon as your payment is processed, you will receive an instant download link on the checkout page, via email, and in your My Account dashboard.
Installation & Troubleshooting
Why does my radio say “SD Card Warning” or play no audio?
This usually happens if the audio files are placed in the wrong folder directory. Ensure that the voice folder (e.g., en) is placed directly inside the SOUNDS folder on your SD card root (i.e., SD Card/SOUNDS/en/).
Why are some file names cut short?
EdgeTX and OpenTX require audio filenames to be short (typically 6 to 8 characters maximum) so the radio’s processor can indexed and trigger them quickly without latency. All filenames in our packs are optimized for this standard.
Can I request a custom voice pack or specific callouts?
Yes! We offer custom sound pack options. Visit our Custom Voice Packs page or reach out through our Contact Form with your requested phrase list.
Orders & Licensing
Can I install my purchased sound pack on multiple radios?
Yes. Your purchase grants you a personal license to install and use the sound pack on any radio transmitters that you personally own. You may not install the sound packs on radios that you do not personally own after purchasing them.
Do you offer refunds on digital packs?
Due to the non-returnable nature of downloadable digital assets, sales are generally final once downloaded. However, if you experience technical issues that our support team cannot resolve, or if you accidentally made a duplicate purchase, please contact us for assistance. See our full Refund Policy for details.
