Stereo Vocal Center Processor
Phase processing, not AI stem separation: reduced center = (L−R)/2; rough center = (L+R)/2. Both are halved to reduce clipping. Centered bass and kick can disappear; widened or double-tracked vocals can remain.

Input ≤50 MiB; decoded audio must have exactly 2 channels, ≤10 minutes, ≤96 kHz and ≤192 MiB. Output ≤120 MiB. These limits are checked after browser decoding; decoding itself may use more memory.

GOOD TO KNOW
Common questions
Is this an isolated vocal or instrumental stem?
No. These are simple sum and difference signals. Other centered sounds can be affected, and stereo vocals may remain.
Is the two-channel output true stereo?
No. It copies the same processed mono signal into both channels.
