VoIP settings

General

Audio processing tab allows you to control the sound quality settings. For real-time internet communication Opus audio codec is used in Virola. It delivers exceptionally low latency and adaptive quality, making it a standard for voice/video conferencing (WebRTC), gaming, and streaming.

Audio processing settings

1.Echo cancellation. This option is needed when a far end signal (voice originating at the other end of a line of communication) is played over a loudspeaker into a reverberant acoustic space and is picked up by a microphone

2.Automatic Gain Control. Automatic Gain Control is an audio pre-processor which automatically normalizes the output of the captured signal by boosting or lowering input from the microphone to match a preset level so that the output signal level is virtually constant.

3.High-Pass Filter. Clears noise before processing by removing high-pitched sound.

4.Noise Suppression. If this option is enabled the noise will be removed from a signal.

5.Noise Suppression with Neural Network. This option is recommended for high-noise environments as it provides aggressive suppression of all external sounds.

Jitter buffer

Jitter buffer is enabled by default. It is a shared data area where voice packets can be collected, stored, and sent to the voice processor in evenly spaced intervals
