Frequently asked questions
How does stereo-to-mono conversion work here?+
The left and right channels are averaged sample-by-sample into a single channel — the standard, phase-safe way to fold stereo down to mono.
Does mono-to-stereo add real stereo width?+
No — it duplicates the same signal to both channels. It's useful for satisfying a stereo-only pipeline, not for actually widening a mono source.
