Audio recordings are a popular tool in hypnotherapy. In addition to direct hypnosis, which takes place between hypnotist and hypnotisand in person, there is also the possibility to perform hypnosis by means of audio recording. In this case, only the voice of the hypnotist is recorded, no digitalization of any kind is used. It is important that the client hears the therapist's voice as unaltered as possible. The client can absorb the audio recording so better and the words can be transported unadulterated, which in turn can lead to a deeper trance and a more intense effect.
