Since Mac Mojave, you can use the stock sound recording app, the Voice Memos, to record any sound, audio, music and voice memos on Mac without third-party audio recorders. Follow this guide to record audio and sounds on Mac using Voice Memos. It is easy and straightforward. iPhone users should be familiar with the Voice Memos app. Its desktop version works almost the same. Sometimes you may need to use a voice recording in a project which requires a different format, such as MP3. In this case, you will need to convert the Mac recordings from AAC, M4A to MP3. Luckily, Mac OS comes with the media player and converter, iTunes, that can help us to get this job done in just a minute.
