This trend has been going on for quite a bit. In fact, it‘s probably super old already but TikTok washed it ashore over the past year or so.
The idea is to speed up or slow down a song by a couple percent which in most cases and the average pitch change algorithm introduces interesting artefacts in vocals and instruments.
Especially vocal tracks move into funny territory, either demonic low growling or high pitch mouse like piping.
So before setting up the final release bundle for Night & Day, I figured I‘ll try to create a slowed down and a sped up version as well, simply to run them on TikTok and see how they perform.
Logic Pro has a functionality called varispeed. This should do.
