How to Use Wwise Rtpcs to Control Volume and Pitch in Live Performance Applications

by

Wwise is a powerful audio middleware tool used widely in live performance applications to create immersive sound experiences. One of its key features is the use of RTPCs (Real-Time Parameter Controls), which allow real-time manipulation of audio parameters such as volume and pitch. This article explores how to effectively use Wwise RTPCs to enhance live performances.

Understanding RTPCs in Wwise

RTPCs are dynamic controls that link game or performance parameters to audio properties. In live settings, they enable performers or sound engineers to adjust sound parameters on the fly, creating a more engaging and responsive experience. RTPCs can be mapped to various inputs, including MIDI controllers, sensors, or other real-time data sources.

Setting Up RTPCs for Volume Control

To set up an RTPC for volume control in Wwise, follow these steps:

  • Create a new RTPC in the Wwise project.
  • Name it appropriately, such as “LiveVolume.”
  • Assign the RTPC to the desired sound object or mixer.
  • Link the RTPC to a controllable input, like a MIDI fader or sensor.
  • Adjust the range of the RTPC to match your volume requirements.

During performance, manipulate the input source to control the volume dynamically, allowing for expressive sound adjustments.

Controlling Pitch with RTPCs

RTPCs can also modulate pitch, adding vibrato or pitch bending effects in real time. The setup process is similar to volume control:

  • Create a new RTPC named “PitchControl.”
  • Assign it to the pitch parameter of the sound object.
  • Connect the RTPC to an input source, such as a MIDI pitch bend wheel or a sensor.
  • Configure the range to allow for subtle or dramatic pitch changes.

Using RTPCs for pitch control can add expressiveness to live performances, enabling performers to alter sound character dynamically.

Best Practices for Live Performance

When using RTPCs in live settings, consider the following best practices:

  • Test your RTPC mappings thoroughly before the performance.
  • Use high-quality input devices for precise control.
  • Set appropriate ranges to avoid abrupt or unintended changes.
  • Combine multiple RTPCs for complex sound modulation.
  • Maintain backup controls in case of technical issues.

With careful setup and practice, RTPCs can significantly enhance the expressiveness and interactivity of live performances.
