Mario Kreuzer - Producer, director (PKM Filmproduktion)
Our cooperation with Frei Audio already exists for more than two decades. Almost exemplary is the constant development of the studio and also the person Andreas Frei to be at the best possible status in technology, quality and efficiency. As nature filmmakers we have to change and adapt plans very often. Pleasant and helpful to know that the sound department will work for us (music composition, SFX, Foleys, voice recording and mixing in Dolby Atmos, 5.1 Surround and stereo) completely carefree. Very rarely, after such a long time of working together, one can claim never to be confronted with personal sensitivities/disputes, which often (because of trivialities) lead to the end of a collaboration. Not only because of the good tone, but especially because of the person Andreas Frei, I appreciate the already long, trouble-free and fruitful cooperation and I am already looking forward to many more projects. Thank you Andreas!
Robert Schabus - Director, producer
Andreas is always willing to openly search for the "right" tone in his work on my film projects, which can sometimes be difficult in documentary feature-length films. This openness distinguishes him not only on the professional side. I always have a valuable interpersonal time with him as well, which is very important to me. And that is always supported by his highly professional approach to film sound and his great studio. It's a stroke of luck for me that Andreas has pitched his tents in Klagenfurt.

The work of the FREI AUDIO recording studio always exceeds our expectations. Andreas and his team prove that it is possible to combine quality, professionalism and creativity. Through years of experience and with a lot of passion, Andreas always creates extraordinary sound worlds for us. For this we would like to thank him very much. We feel enriched by the long lasting partnership and friendship.

Working with Andi Frei is not only professional, but involves an obsessive perfectionism to make films authentic, stirring, quietly breathing or dramatic with the help of sound design to a sensitive mix. Last but not least, he also brings a lot of creativity as a musician to the table, in addition to his organizational talent.
