Selecting the desired audio filtering
• PNR – Uses a generic profile and AI engine to enhance the noise reduction. You can enable PNR for outgoing and/or incoming audio. You can enable the “Low Power” version of the PNR to reduce processing power even further.
• Noise Reduction – Remove ambient noise on your side so your party can hear better.
• Echo Cancellation – Cancel echo on your side so your party will not hear himself/herself. If you are not using headset you should enable this filter.
• Incoming Noise Reduction – Remove ambient noise coming from the far-end so you can hear better.
• Incoming Echo Cancellation – Cancel echo coming from the far-end so you will not hear yourself.
• You can increase/decrease the aggressiveness of noise cancellation and echo cancellation using the matching spinners.
• The “Cancel low voice aggressiveness” spinner controls the aggressive level of canceling low volume human voices. For more information take a look at the following section describing how to cancel human voice.
• “Enable AGC” and “AGC Target Volume”. These two controls can be used to make sure volume level (of both sides) will be aligned with the target volume level. Enable this feature if either you or your party find it hard to hear each other. Increasing the value in the spinner will increase the target volume level.
• “Set Microphone Volume” and “Microphone Volume”. These two controls can be used to decide on the volume change that Windows will do to the output of SoliCall’s Microphone before providing it as a microphone input to the softphone. Enable this feature if the input microphone audio to the softphone is loud and saturated. Reducing the value of the spinner will reduce the volume level.
Cancel ambient human voices using SoliCall Pro
This section explains how to remove ambient human speech using SoliCall Pro. If the volume of the background speech is not loud, then SoliCall Pro should be able to remove it. You can control the aggressive level of this feature using the “Cancel low voice aggressiveness” spinner:
Otherwise, if the background speech volume is loud, there are two options:
1. For co-located PCs we recommend upgrading to our enterprise level SoliCall Connect product.
2. Continue using SoliCall Pro without upgrading and connect a second microphone to the PC as explained below.
