I have a really tight budget, like $70 for audio max. I am looking for a good microphone, but I've never been very good at dealing with the audio side of production. I am shooting on my phone. I don't need amazing quality, but I would like the best quality you can get for that budget. Do you have any suggestions? What type of microphone should I use? I don't know much about audio, so I'm kind of lost with all the different types. Thanks for the help!
