pure:limit is a true peak limiter and per default, the limiter threshold is set to -1.0 dBTP (dB true peak). This value is recommended for most streaming platforms and works well for all digitally distributed media. If you want to use another threshold (e.g. -0.5 dBTP), you can adapt the threshold parameter on the settings page. Please note, that a manually set threshold will only be used for the respective plug-in instance.
