So, say I wanted to say something in audacity, and have it wait like 5-10 seconds before hearing it in my headphones. I just wanted to see if I could mess around the same way callmecarson did in his cool math games stream. https://youtu.be/NB07sW73YVI?t=52 (Timestamp of the video)
You can add a delay effect to something that is already recorded (https://manual.audacityteam.org/man/delay.html) but Audacity does not do effects in “real-time” as you record.
