-# What does the looper do?
-
-*daisy-looper* is a software that can be installed on the [daisyy hardware](../../README.md) developed in the course *Synthesizer DIY* that took place during winter semester 2023/2024 at HFBK Hamburg. The looper allows you to record audio present at the input and [overdub](https://en.wikipedia.org/wiki/Overdubbing) into up to 5 different virtual "tapes" called *buffers*. The recorded sounds stored in each buffer will be displayed as a waveform and can be played back at different speeds (including reverse speed).
