There are many use cases and workflows for each DAW when integrating Sessionwire for remote collaboration. We have created a basic template for each DAW to give an idea of what routing should look like in order to avoid feedback loops between users connected in Sessionwire Studio.

Each user may be using a different DAW or may/may not be using an audio interface - therefore, each user will need to reference the correct signal flow diagram for their particular DAW and setup.

Below are common setups when using Sessionwire alongside Nuendo.


Sending Audio from Nuendo

This workflow is the simplest way to get up and running with Nuendo alongside Sessionwire. Simply placing the Sessionwire Send plugin on the Stereo Out channel of a Nuendo project will produce the same results as in the downloadable template.

Sessionwire's Talkback Input is set to a webcam (or an audio interface with a microphone plugged into channel 1 or 2) and the Talkback Output is set to the system audio output device - this is identical to how any video conferencing software would be set up.

Sessionwire's HQ Audio Input is set to Sessionwire Plugin - Sessionwire will receive audio from the Send plugin on the Master channel of the Nuendo project. The HQ Audio Output is set to the system audio output device - this way any audio streamed from the remote end of the call is sent straight out of the output device. No need to route incoming audio into Nuendo.


Sending and Receiving Audio within Nuendo

This workflow will allow the sending of audio from a Nuendo project while simultaneously receiving remote HQ audio directly into a Nuendo project.

Sessionwire's Talkback Input is set to a webcam (or an audio interface with a microphone plugged into channel 1 or 2) and the Talkback Output is set to the system audio output device - this is identical to how any video conferencing software would be set up.

Two output connections are required to avoid feedback loops in Nuendo - one labelled MIX OUT and another labelled Stereo out. Both outputs are routed to the same physical outputs - typically "interface out 1 and 2". All high quality (working) audio in the Nuendo session is routed to the "MIX OUT" bus which has the Sessionwire Send plugin instantiated, sending high quality audio to Sessionwire Studio's HQ Audio Input. High quality audio being sent by the remote end is returned to Nuendo via the Sessionwire Receive plugin, and sent to the "System Out" bus, avoiding the "MIX OUT" bus and Send plugin. This routing will make feedback loops or delays between local and remote sessions a non-issue.

NOTE: In the Nuendo template, both the MIX and System Out busses are routed to hardware output 1/2 - it is necessary to have both in order to avoid starting feedback loops between users on a Sessionwire Studio call.

To record HQ audio from the remote connection, simply use BitWig's built in routing to select the SW HQ Rcv return track as the input of the destination track.


Using an Audio Interface for All Audio

In this workflow, it is assumed that an audio interface is being used as the input and output device of Nuendo.

A talkback mic is plugged into any channel of an audio interface and the input of the SW TB Send channel is set to the corresponding channel (circled in image above).

Local talkback is routed through the Sessionwire Talkback Send plugin to Sessionwire Studio's Talkback Audio Input.

Remote Talkback Audio is returned via the Sessionwire Talkback Receive plugin and routed to the "System Out" bus, avoiding the "MIX OUT" bus and the Sessionwire Send plugin.

All high quality (working) audio in the Nuendo session is routed to the "MIX OUT" bus which has the Sessionwire Send plugin instantiated, sending high quality audio to Sessionwire Studio's HQ Audio Input.

High quality audio being sent by the remote end is returned to Nuendo via the Sessionwire Receive plugin, and sent out the "System Out" bus, avoiding the "MIX OUT" bus and Send plugin.

To record HQ audio from the remote connection, simply use Nuendo's routing to select the SW HQ Rcv track as the input of the destination track.

NOTE: In the Nuendo template, both the MIX and System Out busses are routed to hardware output 1/2 - it is necessary to have both in order to avoid starting feedback loops between users on a Sessionwire Studio call.
