How to use this workflow
Keep the stereo source
Download the required WAV from Stem Splitter, retain it unchanged, and import it as a stereo clip in your editor. Confirm that the track is not taking only the left or right input. Avoid splitting and panning the channels until you have a reason and an untouched reference.
A channel-routing worksheet
This original worksheet uses hypothetical sample values to show routing consequences. It is arithmetic rather than a listening experiment or a separation result. At one frame let left equal 0.6 and right equal 0.2 in normalized amplitude. Changing routing can change the waveform even when the filename and duration stay unchanged.
Swipe or scroll sideways to read all columns.
| Routing | Left output | Right output |
|---|---|---|
| Preserve stereo | 0.6 | 0.2 |
| Swap channels | 0.2 | 0.6 |
| Copy left to both | 0.6 | 0.6 |
| Average to dual mono | 0.4 | 0.4 |
Locate the change
Compare the downloaded file with the imported clip using the same playback system. A channel swap exchanges sides; a balance control may reduce one side; a mono operation combines them. A central sound alone cannot demonstrate that routing is correct. Use material with a known left/right distinction and keep monitoring volume steady.
Document deliberate changes
Write down whether the recipient should receive stereo, dual mono or a selected channel. Do not call a dual-mono copy the original stereo stem. PitchChanger’s four-stem WAV output is stereo, but that does not guarantee every estimated role has a wide image. The model’s content and the external editor’s routing are separate questions.
Common questions
Does a stereo WAV guarantee a wide instrument image?
No. Two channels can contain identical or very similar material. Preserve them first; judge width from the actual file and the intended use.
