Global credits include Sébastien Tellier & Rose (France), Nikhil Senan (Singapore) & Luiza Caspary (South America). With 1,000+ masters & 15 years experience, I’m an AES & Apple Digital Masters certified engineer. I bring a fresh, unbiased and preset-free mindset to every song, ensuring your music achieves truly world-class sonic excellence.
I am a dedicated mastering engineer, finalizing records daily for a living. Every song I master is approached with fresh ears and full respect for your vision. Mastering takes place in a professionally treated room with phase-aligned, full-range HEDD monitoring and active acoustic correction.
My process begins with meticulous critical listening to understand your artistic intent, along with quality checks to detect unwanted noise, glitches, phase issues, or artefacts. I reference top releases in your genre to ensure tonal balance, loudness, and translation across systems. Processing is applied only when beneficial, using high-end tools such as Shadow Hills Industries, iZotope, AcusticaAudio, and FabFilter. I focus on clarity, punch, and musical dynamics, never crushing your mix unless explicitly requested.
Final deliverables include quality-checked WAV files in 16-bit/44.1kHz (CD) and 24-bit at native sample rate, with proper dithering, metadata, and optional high-resolution formats. Two revisions are included; additional revisions or new mixes are charged separately. Turnaround varies with project and schedule, and rush delivery is available.
I also provide guidance on preparing mixes for mastering and tips for optimal results across streaming platforms, vinyl, or physical releases. I look forward to helping you bring your music to its polished form with confidence!

I had approached Jean after seeing one of his very competent comments about mastering on Reddit, because I was just looking for a mastering engineer who could remaster one of our songs.
From the initial contact, through the suggestions for improving my mix, the actual mastering and delivery, the collaboration with SoundWise Mastering was a fully professional experience. I will be very happy to return for future jobs.It sounds great, good mastering and communication with Jean-Marc.
He'll do the mastering of my album "Human"It was great working with Jean-Marc. He was a clear communicator, he completed his work on my songs in a timely manner, and really made my songs jump out of the speakers and sound great. I highly recommend him for mastering.
I went for a vocal recording session with SoundWise in March 2022, and thoroughly enjoyed it! Jean-Marc was quite professional and well-prepared for my recording session and provided helpful feedback in areas of my song where I was unable to identify the weak spots. The studio is well-equipped and the overall atmosphere was quite welcoming and creative. Would definitely be coming back again!
Jean Marc Boulier is my go to choice for mixing and mastering. He has been the recording genius behind my band, Revoir.
He takes into consideration how the band wants the music to sound. Truly one of the greatest recording masters I've had the pleasure of working with.
Great Job from Jean-Marc, an accurate mastering !
