The 32-Bit depth support allows for a wider dynamic range and increased detail in your recordings. To encode and decode audio data, we utilize the Opus codec, a royalty-free, highly versatile audio codec that is unmatched for interactive speech.¹ The low algorithmic delay of Opus (5-10 milliseconds) makes it the perfect fit for streaming audio from your phone to your desktop PC. For networking with your PC, Micstream uses the UDP protocol on ports 37718 to 37720. The UDP broadcasting feature enables automated client discovery in wireless mode. Micstream also uses FEC (forward error correction) to handle packet loss.
