Voiceover / speak is a difficult discipline. Not just for the speaker, but also for the technician / producer.
Besides having to be aware of errors, mishaps and general correction, post-production is just as important. Noise reduction, track cleaning and rules for loudness (measured in LUFS) are important for a good and correct result.
5th Vision has performed speaks / voiceover for meditations,
e-learning and apps.
The sound studio 5th vision was founded in 1998 by multi musician and producer Carsten Falkenlind.
