If you add a hardware audio interface of your choice (AD/DA: analog-to-digital/digital to-analog) and a microphone, you have a complete recording studio, suitable for recording anything from a soloist to a band to an orchestra (even if the orchestra is just you).
Using your current computer and no other software, you can import any audio and MIDI, synthesize, sample, compose, arrange, edit, mix, and master songs or any other audio projects.
REAPER is a digital audio workstation: a complete multitrack audio and MIDI recording, editing, processing, mixing, and mastering environment.
