SoliCall Pro Integration – Advanced

Selecting the desired audio filtering

PNR – Uses a generic profile to enhance the noise reduction. You can enable PNR for outgoing and/or incoming audio.

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.

• The two sliders for noise reduction aggressiveness and echo cancellation aggressiveness control the aggressiveness of the filters. Increase aggressiveness by moving the slider to the right and reduce aggressiveness by moving the slider to the left.

• The “Remove low voices” slider, activates the feature of removing relatively low volume human voices. You can increase the aggressiveness by moving the slider to the right. If you take the slider all the way to the right, it will increase aggressiveness of noise removal but also increase the chance of removing low volume speech of the primary speaker. If you take the slider all the way to the left, the feature is disabled. If you suffer from significant ambient human voice then take a look at the following section describing how to remove human voice.

•  “Enable AGC” and “AGC Target Volume”. These two controls can be used to 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. Moving the slider to the right 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. Moving the slider to the left will reduce the volume level.

 

 

 

Removing 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 relatively low, then SoliCall Pro should be able to remove it. You can toggle the aggressive level of this feature using the “Remove low voices” slider:

 

Otherwise, if the background speech volume is relatively high, 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.

Connecting a second microphone

Place the second microphone (a.k.a.  “reference microphone”) at least 1 meter away from you and facing the source of noise.

External USB microphone

Then, open the advanced options menu, enable RNR and select the second/reference microphone.

When RNR is enabled, for best experience we recommend to use headsets.

The controls “Set Microphone Volume” and “Microphone Volume” can be used to control the level of audio that is received from the reference microphone. Use these controls if the volume of reference microphone is loud and saturated.  Moving the slider to the left will reduce the volume level.


Connecting to Old VoIP Application

If you are looking to improve your voice while making calls via old VoIP application that does not allow you to select the SoliCall microphone, two settings should be done.

1. Open SoliCall Pro option screen and select you specific microphone OR in case the microphone might change, select “Any Available Device”.
