The inability to direct audio output from an application designed for audio streaming (such as an “audio relay” application) towards other software on a given system represents a functional limitation. This scenario manifests when a user intends to capture or process the audio stream transmitted by the relay application using another program, for example, to record the audio or apply effects to it in real-time. Functionality is hindered when the operating system or the applications involved do not permit the rerouting of audio streams. An example would be trying to use a digital audio workstation (DAW) to process audio being streamed from an application intended for remote audio sharing, but the DAW is unable to recognize or access that audio stream.
The capability to redirect audio streams offers significant utility in various contexts. For content creators, it enables the combination of multiple audio sources for streaming or recording purposes. Audio engineers can utilize it for advanced signal processing and effects routing. Gamers may employ it to capture in-game audio along with voice communication for recording or live streaming. Historically, achieving this required specialized hardware solutions. Now, software-based solutions are more prevalent, offering increased flexibility and cost-effectiveness. The limitations described restrict these and other potential use cases that rely on audio stream manipulation.
