Comparison should be fair.
Audio processing can easily fool us.
A signal that is slightly louder often feels clearer, wider, punchier, or simply "better" even when the processing itself did not improve it.
That is why nClear Audio treats comparison as part of the processor rather than an afterthought.
Effects should provide A/B state comparison or a proper bypass workflow, and gain matching / Auto Gain wherever it is meaningful.
The same principle applies to product demonstrations. Before-and-after comparisons should make the plugin's contribution clear. Changes in the source material, undisclosed additional processing, or unmatched loudness should not be presented as improvements made by the plugin.
Descriptions should explain what an effect does and where its limitations are. Creative control names are welcome, but the documentation should explain what they control, not disguise familiar processing as a secret formula.
If a processor sounds better only because it got louder, it doesn't sound better.
