- A normalized sound with a DC offset will not reach its highest volume during audio processing because the offset consumes the headroom. This problem can extend to the mix as a whole since mixing a sound without a DC offset with a sound with a DC offset will cause the first sound to have a DC offset.
- Any signals with recursive DSP algorithms applied are likely to be very sensitive to audio files with DC offsets and this will cause artifacts. This is especially the case for Reverb plug-ins as well as Environmental FX plug-ins.
Since the DC offset is not removed at run-time because this would result in un-optimized performance issues, it is recommended to remove the DC offset before importing the files into Wwise, using a DC offset removal filter that is available in most audio authoring tools or during the conversion process in Wwise (in the Conversion Settings window).
