Kamran,
While the newer cell phones out there do a good job of recording audio, you can do a lot better with a minimal investment. Look into a battery powered Lavalier mic that you can plug into your cell phone. The quality of your audio will sound considerably better. You just have to decide if you want a mic that is directional or omni directional.
Don’t you live in NJ? Shoot me a PM. If you want I could send you mine to try out…and if you like it, you could buy one for yourself. If there is not enough time before you leave…you could use mine at Decfest.
Mine is a Aputure A. Lav Omni directional mic. Not sure if mine is available anymore, but you can do a search for lavalier mics…word of advice just get one that is hard wired to you phone vs a Bluetooth version. I think that you will get better results. The company Shure, Sennheiser, Rode, and Diety are very popular companies…so maybe take a look there. The Sweetwater website is a good place to start. Mine is tailored for cell phones…so just make sure that it’s specified for that purpose. The battery powered ones are nice since it doesn’t consume any power from your cell phones battery.
When I attended Decfest like 4 years ago…I took a bunch of video clips that I had posted on YouTube. I wish I would have had that lavalier mic for those recordings. So when you are sitting in the Decware main room and listening to music…make some video recordings with the Lavalier mic attached….they will come out great.
here is a link to my microphone…
I found my mic online at this website if you are so inclined to buy it…

Do your due diligence and read up these mics…they can get quite technical. You may need an adapter cable to go from the mic into your cell phone depending on what brand cell phone you have, and what accessory cables the mic comes with in its package. My apologies in advance if I am taking down a rabbit hole.
