Convert between mono and stereo, or pull out just the left or right channel — same audio content, different channel layout.
Mixes both channels down into a single centered mono track — the safest, most compatible option.
Most audio is either mono (one channel, sounds the same everywhere) or stereo (two channels — left and right — that create a sense of width). Channel conversion changes how a file's audio is laid out across those channels, without changing the pitch, tempo, or content of the audio itself.
Merge a stereo track down to mono, duplicate a mono track into fake stereo, or split a stereo mix apart to grab just one side — useful whenever a channel isn't the one you actually need.
Convert to mono, convert to stereo, extract the left channel, extract the right channel, or swap left and right — pick the one you need.
Merge a stereo interview recording down to mono so both speakers sit centered and evenly on every device.
Some karaoke tracks hide the instrumental on one channel and vocals on the other — extract the instrumental-only side directly.
Turn a mono voiceover into stereo so it matches the channel layout the rest of your timeline expects.
Fix a file where left and right accidentally got swapped during recording or export.
Pick mono, stereo, extract left, extract right, or swap left/right.
