nanoStream Webcaster Client Release 5.8.0

Release Notes

With this release we are adding audio preprocessing options to your webcasts. This may enhance audio streaming quality for music and other high-bandwidth non-speech signals. Background information: By default, WebRTC browsers add specific audio processing filters to enhance the quality of speech-based signals e.g. in video conferencing or screen-sharing applications. These speech filters reduce noise and possible echoes during conferencing, but also have an impact on audio quality for music and other non-speech signals. Disabling these filters improves the quality of music streaming.

Suggested configuration for music streaming:
Disable all filters: “echoCancellation”, “autoGainControl”, and “noiseSuppression”. Potentially keep “noiseSuppression” on.

Note:

Disabling “echoCancellation” may lead to feedback loops while microphone and loudspeakers are enabled in the same room.

Suggested configuration for speech-streaming:
Use the defaults or enable all filters: “echoCancellation”, “autoGainControl” and “noiseSuppression”.
