How can we learn to be Andhadhun and what is its future?

I am Andhadhun. I can work in bars, KTV, hotels, film and television production centers, recording studios, and even sauna. What you say about the future depends on the level. You need to know how to maintain if you want to go to the advanced level or above. If you can't find a job, you need to work on your own, open a repair shop, and then you can take the exam as a sound engineer, make an album for singers, and make a post-Andhadhun for film and television. First of all, you need to be very good at physical acoustics and know how to calculate the room. Make up for the acoustic defects of sound reinforcement. Secondly, electrician knowledge should be excellent and know the matching of impedance and power, so that you can configure your own sound reinforcement system. If you want to research, you need to know microcircuits, electronic components, equipment structure and tuning technology. In short, sound reinforcement is very professional. If you think differently, you should learn to be a sound engineer, but the employment is too narrow.

I hope to adopt it.
