Summarize this article in one sentence.
You need to find a nice quiet and calm place to make your recording. If you are recording it on your computer, your bedroom could be ideal. Make sure you do it at a time of day when you will not be distracted and there is not noise coming from outside your room. To make a good recording you will need to be relaxed and in the right frame of mind.  Put aside plenty of time so you can relax before you turn the recording device on. You have to be relaxed when you make the recording, if you want it to be relaxing when you listen back to it. One way to guarantee you will not be relaxed when you are trying to make the recording, is having faulty or unreliable equipment. Spend some time getting to grips with whatever recording device you are using before you get started. Do some practice runs where you record yourself talking normally until you are completely confident. Before you begin recording, read through the script from start to finish and think about your voice and delivery. It’s not just what you say that’s important, but how you say it. You will find it hard to relax if you are listening to a voice shouting at you to do so. Equally, your voice must be engaging enough that the images you create have an impact on you, and help you visualise the scenes.  Try using different dynamics in your voice, including slow quiet parts, and faster louder parts. Experiment and try different things. There is no single way to make a good recording, it’s all about what works for you. Try to engage with the content of the script as you say it. If you are describing a calm sea, try to picture that in your mind as you read it. When you are fully relaxed and prepared, start your recording. Try and get all the way through in one take on your first go. Concentrate on the words and the images you are creating. Try to be in the moment and really engage with the script you have prepared. Monitor the tone and speed of your voice, but let yourself be carried on the words as much as possible. Once you have made a complete recording listen back through it. You might want to listen through it a couple of times before you try to use it for hypnosis. It will probably take you a few attempts to get it sounding how you like, so expect to make multiple recordings. Try to learn something from each recording you make and you will get better and better.  Pay attention to how your voice sounds, and the tempo of you delivery. Maybe you will need to speak a bit more animatedly, or perhaps more slowly. Once you have got the hang of the recording you might want to try and add some extra elements to complement your words. If you have some editing software on your computer, you could add some relaxing music to go along with the text. Feel free to experiment with different ideas and keep an open mind about what might work for you.

Summary:
Prepare a quiet space. Check all the equipment is working. Consider your voice and tone. Record your script. Listen through it. Consider adding music.
