cant record my voice over karaoke tract

hi

i cant import the mp3 karaoke track but when i click record, the program does not play the song in my earphones so i do not know when to sing since i cant ear the mp3.

how to solve this

Audacity 2.0.5 is very old. The current version is 2.2.2 and is available here: https://www.audacityteam.org/download/

For “overdub” recording (recording a track while listening to other tracks), the settings at the bottom of the Transport menu should be:
Software Playthrough: Off (not selected)
Overdub: On (selected)

thx it fixed the prob.

what are the downside of using an old version if you can explain them to me i m not sure to see the pros and cons of upgrading

tx

There have be a lot of changes since 2.0.5.
The change log up to version 2.2.1 can be viewed here:
