Greetings, in this Unity tutorial we shall be looking at how to record audio from an input device like a microphone and save it to a wav file. This Unity tutorial will take you from an empty Unity project to a Unity project that functions as an audio recorder in Unity.

So in this tutorial we will be using the Unity microphone class to record audio from the microphone. We will be recording to an audio clip that is 3599 seconds long. Once we finish recording we will trim the audio clip to only be as long as we were recoridng for. This is to not waste space by having a huge wav file with mostly empty sections.

When we create a wav file we need to reserve the first 44 bytes for the wav file header. A file header is data within a file that contains identifying information about the file and possibly metadata with information about the file contents.

We also convert the audio clip we recorded in Unity into byte data so we can write it to the wav file. All wav scripts used in this Unity tutorial on recording audio is in the description for you to copy and paste. (Just use the pastebin links).
