There are so many DAWs out there nowadays, and many are totally free! Some are even robust, non-software based, online only software you can use just by logging onto a website. My favorites are:
*Audacity for straight audio recording. It's cross-platform (Windows, Mac, and even Linux):

*Soundtrap for sequencing and audio - I use it with my students since it even has a "collaboration" feature they can add to a song with on their computer live:
