    Zeitstill did an amazing job mastering my latest lofi-ish vocal/piano/liquid dnb track

    He was able to fix all the issues of a track i lost the project files from in the most precise way.

    His communication is great and i really enjoyed to work with him. I will definitely ask him again for the special something on the master you rarely get from other engineers.

  2. Review by stfnkrl

    Really enjoyed working with Zeitstill on my Mastering! Attention to Detail, great feedback on my mix and flexibility in the process. Would highly recommend.

  3. Review by elenandrew_music

    A competent mastering of Zeitstill. Communication worked well. Everything okay. Thanks.

  4. Review by Seraina F.

    Top notch as last time! Constantin did another great job in mixing and mastering my recent project. He always listened to my feedback during the process and throughout a couple of versions the result got exactly like I wanted. He does not only provide versions of the mixes (or masters) but always adds a note about how he's been working on the tracks. Easy and professional to work with!

  5. Review by Elen Andrew

    Very gentle, balanced master. Zeitstill really got down to business here again. Great in all aspects: mastering, mixing instructions, support. Very good work.

    Constantins masters are real differentiated works on your tracks. Most importantly he does not master your tracks only by making them louder. Since I'm working with Constantin I can really hear and appreciate the difference good mastering makes. His fine-tuning somehow does enhance the overall feel of my compositions as I have not experienced it before when working with mastering engineers.
    Last but not least he is always very receptive to artists feedback - something I appreciate a lot!

  7. Review by Elen Andrew

    A wonderful experience was all the help an input i got from Zeitstill. I highly recommend him as an engineer, person and also as an art-savvy person with a sense for the big arches, the whole. He just has that certain something. Time stands still when we work together. He deserves recognition on SoundBetter. I've rarely had a better engineer here!!

    Although his page did not show a long list of samples the ones he showed was enough to compell me to give him a try, and it worked out fine.He gave my Jazzy/Rock instrumental warm tones and thunderous lows to give it the perfect balance in tonality.I'll definitely like to work with him in the future.

  9. Review by Elen Andrew

    This track came out really magical. Like a dream. I love how Zeitstill mastered my mix.
    The heart of a teenager in love, as the track is called, now feels like real heartbreak. It hurts, but it lives, and it shines and sparkles... A sound that only Zeitstill can achieve.

  10. Review by Elen Andrew

    What an experience. From a very good sounding retro trance/ambient track we came together to an even better, independent result with character. The extra mile was worth it. Zeitstill is highly recommended. He knows what he is doing.

  11. Review by Elen Andrew

    I just wanted to thank you for what you've done for my music. I've never felt my own songs like I did through your master(ings)!!
    You have always given me very valuable tips. I think you're not only an excellent engineer, you also have a feeling for the whole, the art, and I think we harmonized very well.
    I hope this will continue...

  12. Review by Elen Andrew

    Zeistill is a brilliant engineer. I can't say much more this time, I would just repeat myself. Simply great! I was blown away by this new master. Exactly how I wanted it! Thanks!!!!

  13. Review by Seraina F.

    Constantin cooked up a clean and transparent mastering with big time loudness for the piano piece I provided. Completely different project than the one I had mastered from him before but equally as good!

  14. Review by Elen Andrew

    Top skills up to date. Mad Ear. Limitless patience. No mile is too far for him. Mastering at its best. Thank you, this master is sick.
    What have you got to lose, choose Zeitstill for your next track!

  15. Review by Elen Andrew

    Zeitstill did it "One More Time": He is a super engineer with a lot of demands on himself. His results are created with somnambulistic understanding and imaginative skills. Woven into what I'm looking for in my music.
    "Imagination redeems us, and the dream is our liberator."

  16. Review by Elen Andrew

    Zeitstill did a fantastic job. It's not just a simple master, he was able to implement all my visions with pinpoint accuracy. This engineer is damn good and one of my favorites here on SoundBetter. Handshake! Elen.

  17. Review by Elen Andrew

    Zeitstill did a fantastic mixing/mastering job for my new track "alone". Great communication as always and nothing is too much for him. He tries very hard as if it were his own music. I thank you ! You took my music to the next level ! Creative and totally gifted, that's Zeitstill !!!!!

  18. Review by Seraina F.

    Awesome experience with Constantin. The mastered tracks sound very balanced and came with this extra touch we are all looking for! He worked in my feedback for the first sketch perfectly. In general very pleasant communication. Highly recommended!

    I've been working with Constantin for a while already. About a year ago he mixed and mastered my first release ever (an 8 track drone/ambient album). He was not yet offering his services on SoundBetter at the time, but I was already highly satisfied with his work. He now did an awesome job again for mastering my most recent techno track. I learned a lot through his mixing advices from the time we worked together and could provide a much better mix already. Constantin really does put in the work!

  20. Review by Elen Andrew

    Zeitstill is absolute perfection. He does everything to make your track sound great. Zeitstill is passion, creativity and highly talented. I can only recommend this engineer, you won't regret it. I'm glad to have worked with him. Last but not least: the communication is excellent. And the mixing advices are gold. 5 Stars!!!

  1. Q: What do you like most about your job?

  2. A: I just really like sound.

  3. Q: Can you share one music production tip?

  4. A: Know your tools, read the manuals so the expression of your creative potential won't be limited.

  5. Q: What are you working on at the moment?

  6. A: Right now I am working on 3 film projects where I am composing and producing the film music.

  7. Q: Analog or digital and why?

  8. A: Both. It depends highly on the material. There is no worse or better and I just use the best from both worlds!

  9. Q: What's your 'promise' to your clients?

  10. A: I will make your good sounding recordings and productions sound even better and professional. Ready to be streamed, sold and published.

  11. Q: What's the biggest misconception about what you do?

  12. A: There is magic in mixing and mastering but only to some degree. My service can only be as good as the initial work you put into your project. I am gladly gonna offer you feedback though, if I think there is still some work to be done beforehand.

  13. Q: What advice do you have for a customer looking to hire a provider like you?

  14. A: Communicate first.

  15. Q: If you were on a desert island and could take just 5 pieces of gear, what would they be?

  16. A: My MacMini, my monitors + interface, my MFB Tanzbär, my Eurorack and a MIDI-Keyboard.

  17. Q: What was your career path? How long have you been doing this?

  18. A: At the age of 14 I stopped having piano and drum lessons and I shifted my interests to modern music production in a DAW. After graduating from school I moved to Berlin to discover new sound worlds for one year. Then I studied Sound & Music Production in Darmstadt for 4 years and since then I am working as a freelancer.

  19. Q: How would you describe your style?

  20. A: Since I learned to play the piano and the drums growing up, I am musically and rhythmically trained. I am always looking for unheard, sophisticated rhythms and melodies and the combinations of those, while staying minimalistic. There is always something to discover in my music.

  21. Q: Which artist would you like to work with and why?

  22. A: I would like to collaborate with Caterina Barbieri.

  23. Q: What type of music do you usually work on?

  24. A: I usually work on electronic music but I am not limited to it by any means. I am open for every genre.

  25. Q: What's your strongest skill?

  26. A: My strongest skill is to have an analytical ear but also great empathy to really understand the soul of your project and what you are trying to convey.

  27. Q: What do you bring to a song?

  28. A: I bring my ears and my expertise.

  29. Q: What's your typical work process?

  30. A: Typically I am working everything out with the client first so everyone knows what he gets and what to expect. Then I usually start immediately with the work and try to get it done within one week. (depending on the schedule and the project size)

  31. Q: Tell us about your studio setup.

  32. A: I am working on a MacMini M1 machine, which has the power for big projects as well as for CPU hungry plug-ins. My monitors are Neumann KH310, which are the most neutral and linear sounding monitors I know and they will reveal anything which isn't quite right (yet). They are supported by my second pair of monitors which are the Yamaha NS10s. I also have 2 pairs of headphones (Beyerdynamic and Sennheiser) for the little details. I have high quality mixing and mastering plug-ins by the likes of UAD, Waves, Fabfilter and Softube. If your work needs an analog feel, I am summing it on my old vintage analog mixing desk. If your track needs some instruments to be replaced I have high end synthesizers, drum machines and samples.

  33. Q: What other musicians or music production professionals inspire you?

  34. A: Caterina Barbieri, Henrik Schwarz, Weval, Tobias Neumann, Stimming, Trentemøller, The Dø, Portishead

  35. Q: Describe the most common type of work you do for your clients.

  36. A: I am mostly doing mixing and mastering jobs for my clients, but also support them with their recording and production to help them fulfill their vision.
