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!

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 🙂

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.

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!

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!

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.

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!

FREQUENTLY ASKED QUESTIONS

Everything you need to know before starting your project.

Find answers about services, file preparation, revisions, delivery and the online workflow. If you are still unsure about what your project needs, send your files and we will review them before payment.

Which service is right for my project?

If your song is already recorded and produced, Mixing & Mastering is usually the right choice. If your vocals need tuning, timing correction, cleanup or additional processing, Vocal Tuning & Mixing may be more suitable. If you still need arrangement, instrumentation, sound design or help developing the song, Music Production is the best starting point.

If you are not sure, send your files and describe your goals. Your project will be reviewed before payment so the most appropriate service can be recommended.

Mixing is the process of balancing and processing the individual elements of your song, including vocals, instruments, effects and dynamics. The goal is to create a clear, cohesive and emotionally impactful mix.

Mastering is the final stage. It prepares the completed mix for release by improving overall balance, loudness, consistency and translation across headphones, speakers and streaming platforms.

Yes. Many projects begin with vocals recorded in a home studio. The final result will depend on the quality of the original recording, but noise reduction, editing, tuning, timing correction and professional processing can significantly improve the sound.

Before starting, the files can be reviewed to identify any recording issues and determine what can realistically be improved.

Yes. Podcast episodes, interviews, voice recordings and other spoken-word projects can be edited and processed to sound cleaner, clearer and more consistent.

Depending on the project, this may include noise reduction, removal of unwanted pauses or mistakes, volume balancing, equalization, compression and final loudness preparation for online platforms.

Export each track from the same starting point so everything stays synchronized. Whenever possible, send WAV files without limiting, clipping or heavy processing on the master channel.

You may also include a rough mix, reference songs and notes explaining the sound, mood and result you are looking for. Files can be shared through a cloud storage or file-transfer link.

Absolutely. Reference songs are highly recommended because they help communicate the tone, balance, vocal character, energy and overall direction you want.

The goal is not to copy another production, but to better understand your artistic vision and create a professional result that still feels like your own music.

First, your files and project details are reviewed. You will then receive feedback about the material, a recommendation for the appropriate service and a clear quote.

Once the project is approved and payment is completed, the production process begins. You will be able to communicate directly about your goals, references, feedback and final sound.

Revisions are part of the collaborative process and allow you to provide feedback after receiving the first version. The exact number and scope of revisions may depend on the selected service or package.

Clear notes and reference tracks help make each revision more efficient and bring the project closer to your intended sound.

Turnaround time depends on the service, project complexity, number of tracks and current schedule. After reviewing your files, you will receive an estimated delivery timeframe together with your quote.

If you have a release date or specific deadline, mention it when submitting the project so availability can be checked in advance.

You will receive professional, release-ready audio files prepared for the intended use of your project. Depending on the service, this may include high-resolution WAV files, listening copies and additional versions agreed upon before the project begins.

If you need instrumentals, acapellas, stems, alternate versions or specific technical formats, mention this when requesting your quote.
