Routing is a selection, not a stereo repair
Each output channel can use original left, original right or silence. Mapping left to both sides creates dual mono; it does not recover information missing from the right side. Swapping channels changes their placement without correcting phase, balance or microphone timing.
Review the second download too
The audition control plays the first rendered WAV. In split mode, open the second file separately to check the other channel. Both outputs preserve the input sample rate and duration, while their sample precision is reduced to PCM16.
Questions about Stereo Channel Splitter and Router
Does splitting combine the two signals?
No. Each mono download takes one input channel. Use mapped stereo output for duplication or swapping.
Can I listen to both split files on this page?
The audition control plays the first rendered file. Open the second download separately to check its channel.
