Adjust audio gain and delay
Pearl Mini does not introduce audio delay and has near-zero latency when capturing. However, other external
factors can cause audio to become de-synchronized, such as the length of audio cables or the configuration of
your equipment. The audio delay feature helps you adjust audio coming from external sources so that your
video and audio sources are synchronized when captured, streamed, and recorded.
By default, there's 0 ms of delay applied to your audio sources. You can set the amount of delay for any audio
source using the Admin panel and apply from -300 ms and +300 ms of delay.
Adjusting the Input Gain for an analog audio source affects the volume for that audio source in recordings,
streamed output, video output ports, and in the headphone jack. Be aware that excessive amounts of gain
can increase the perception of any noise that may be present in the audio signal.
