Audio Processing and Noise Suppression

High audio quality is very important for calls and meetings, as it helps make communication more efficient. Without proper noise suppression and echo cancellation, background noise and other disturbances can interfere with conversations and reduce your team's productivity.

In Virola, we have implemented the best modern technologies to improve audio quality and eliminate external sounds during voice and video meetings, as well as while sharing your screen.

All options on the Audio Streamer tab in the Virola Client settings affect outgoing audio quality. By choosing the right combination of settings, you ensure that your teammates can hear you clearly.

To get the most out of the noise cancellation techniques built into Virola, we recommend keeping the default Audio Streamer configuration:

• Echo Cancellation prevents your teammates from hearing their own voice echoed back through your microphone during calls or meetings. This option is especially useful if you are using especially or very sensitive microphone. Virola users acoustic echo cancellation (AEC).
• Automatic Gain Control (AGC) regulates your outgoing audio signal to maintain a consistent volume level. It boosts quiet sounds and attenuates loud ones.
• High-Pass Filter removes low-frequency noise and improves overall audio processing.
• Noise Suppression increases the signal-to-noise ratio in the audio signal.
• Noise Suppression with Neural Network provides aggressive noise reduction, effectively blocking keyboard and mouse clicks as well as background noise, leaving primarily your voice. However, it may also alter the sound of your voice, so we recommend enabling it only in high-noise environments.

VoIP Streaming

A new experimental VoIP Streaming engine was implemented in Virola. If enabled by option Use the modern version of the audio streamer, it is used during audio/video meetings. Note! Virola Client and Server version 2.7.1 or higher should be used by all meeting participants to try this option.
