WHAT ARTISTS SAY/reviews
Real feedback from artists who trusted MIXBYPROS with their songs.
Sweden
This was my first time working with Andre, and it was awesome! His skills, attention to detail, and speedy delivery was way beyond my expectations. But what impressed me the most was his commitment. He gave me good advice and willingly shared his expertise. And instead of rushing an approved delivery he told me to take my time and get used to the new audio. And after a single small revision that was entirely because of flaws in my own recording, he delivered a polished track that's ready to drop in my DAW. This gig is highly, highly recommended!
United Kingdom
Working with Andre was an outstanding experience.Not only is he polite and helpful he is also very professional at his work.I recorded one of my songs using suno and the voice in the second half of the song sounded nothing like me.Andre worked his magic and resolved the problem.I am extremely happy with the end result and appreciate the professionalism of Andres work.Thankyou Andre.Highly recommend this gig.
Germany
Andre was a pleasure to work with from start to finish. He put a great deal of care and attention into the project, delivered a professionally polished vocal track of outstanding quality, and was always friendly, responsive, and committed throughout the process. I highly recommend Andre and would gladly work with him again in the future 🙂
Canada
I came to Andre with a single I had previously worked on with another producer. After being told the track couldn’t sound any better, I felt discouraged and started to believe my vision might not be achievable. I was close to scrapping the project entirely when I came across Andre’s profile. Working with him turned out to be the best decision I could have made. He was patient, truly listened to my vision, and encouraged me to push further to get the sound I wanted. He didn’t just improve the track, he elevated it. The production reached a level I honestly didn’t think was possible. I couldn’t be happier with how it turned out. I’m so grateful to Andre for bringing this vision to life.
United States
I had previously given my song to a different sound engineer on this app. After 3 weeks and excessive money spent on the job, he returned something horrendous. I then turned to this engineer and he exceeded my hopes. He was quick with return, polite, and made my song sound like what I heard in my head! Will 110% be using him again!
United States
Andre is incredible! He took the time to truly understand my song and the warm, immersive atmosphere I wanted, and the finished result exceeded my expectations. He preserved the emotion and personality in my vocals while making everything sound polished, cohesive, and professional. His communication was thoughtful and detailed, he was extremely receptive to feedback, and the few revisions I requested were handled beautifully. Most importantly, he gave me so much confidence in my own voice. The final song sounds like me, just elevated into the version I always hoped it could become. I couldn’t be happier with Brain Chemistry and I’m already excited to work with Andre again on my next song. I wholeheartedly recommend him!
Switzerland
Andre is absolutely amazing. I am assembling top-notch talent to create a comprehensive world-class workflow for music production and he is a key part of my team now. He is a professional musician who has also mastered the technical side of vocal tuning and music production. I have multiple jobs to give to him and feel really fortunate for the opportunity to work with someone so professional, who is also flexible, nice and cool. Andre gets my highest recommendation.
Bulgaria
Andre was very polite and very patient! He never made me feel like I'm rushed! With every new revision we got closer and closer to my desire result. I know the task I gave him was probably hard and I know I had big expectations, but he somehow manage to live up to that expectations and make the mix exactly as I wanted it to be! Thank you, Andre! For the price you delivered more than just a mix, you delivered an experience!
