SDA2WAV is a simple C# Program that allows you to convert the .streamDeckAudio format to a .WAV file. This is useful for individuals looking to use the free audio assets from Stream Deck outside of their software. Elgato uses a simple XOR Obfuscation to create their “proprietary” audio format.
[NOTE:] During more recent research in writing a version for Linux users based in Go, I found that Elgato is using the AudioBlocks API for their audio assets. There could be licensing issues when using the audio outside of the Elgato suite. I am not an attorney, do your research, make the choices you feel are best. I am not responsible for any licensing issues that arrise when using my application to convert these files.
