Been using Audacity for dozen years on Windows7 for multi track recording. Work great, never had any issue.
Got a new laptop with Windows10. Install the latest Audacity and ran into strange issue described below.
- record a music track first (no issue)
- record a second track, singing vocal based on the key of first track
When playing back the second track sounds of pitch, one full step above my singing voice (for example, if I sing DO RE MI, play back second track will sound like RE MI FA#). Tried the old version of Audacity that I have on Win7 PC. Same problem. Tried latest Audacity with Win7, work fine.
