There is another Zoom audio setting which will suppress some of the room noise and reverberation. In other words, if the mic cannot reference the speaker within the device itself, this can be enabled for echo cancellation and audio optimization.
This will be selected automatically whenever the input and output devices differ. To enable the Zoom echo cancellation, on the Zoom Room controller, tap Settings, then Microphone, then tap the Echo Cancellation toggle. Zoom can hear multiple independent channels of audio in certain applications and apply processing to each channel of audio for an optimized experience. Zoom will do all of the optimization based on adaptive processing to learn the room and optimize the audio. There is no need for an external device to do this processing for you if you need to use a mixer or other microphone source that is not integrated with a speaker output. Here is an overview of Zoom Rooms echo cancellation: ProAV Divisible Space (w/ ceiling & presenter mics).ProAV Training Room/Classroom (w/ ceiling & presenter mics).ProAV All Hands Space (w/ presenter mics only).ProAV 3-Screen (6-10 people w/speaker tracking camera).ProAV Conference (9-19 People w/ceiling mics).ProAV Conference (7-13 People w/table mics).If any adjustment is made after the initial setup, Zoom SAP may be automatically enabled, which would not be desired in this situation.įor external DSP designs, please reference: It is important to note that certain devices have been developed to automatically disable Zoom SAP upon selection. Since Zoom is not handling the DSP in this instance, Zoom Room noise suppression should be disabled. If the input and output device are the same, such as a Logitech Rally System, Logitech Meetup, Aver VB342, Polycom Trio, or rack-mounted DSP, that device will handle all of the audio logic that is needed to have an optimal audio experience.
#TEST ZOOM MEETING FROM ZOOM ROOM SOFTWARE#
The DSP is external to Zoom and all processing and relationship between mic and speaker is completely external and Zoom's Software Audio Processing has been disabled.Zoom's Software Audio Processing is enabled and the external mic and speaker are independent and unaware of each other.There are two approaches to audio processing in a Zoom Room: Audio Processing Methodsĭigital Signal Processors or DSP are audio processors that are software based and may have associated hardware which optimizes audio for different applications. There are two methods for processing audio within a Zoom Room. All of the steps along the way play a role in the perception when it hits the human ear.
The audio is turned back into audio waves by speakers so that you can perceive that audio. The Zoom Room takes that audio, processes it if needed, and transmits it over the internet. We represent our ears as a microphone that hears this audio. In a video conference, a few extra steps are added to that explanation. Microphone Quality & Proximity to SourceĪudio is vibration that travels through air that can be perceived when it reaches an ear.The following are all factors along the way: Think about everything that happens from the word being spoken to that word being heard by a participant on the far end. Once the room sounds good, we can proceed into how we capture that experience. In this article, we will discuss many of the concepts and features that are most important when thinking about audio performance in a Zoom Room design.īefore we dive into the technicality of audio process from end to end, please review our article on Acoustics & Audio Concepts. Without audio, the meeting cannot happen.
Audio is the most important aspect of your Zoom Room!
