Over the years my refinement of anomalous audio files has become simplified. The more filtering one induces into the file, the more it ALTERS and changes the original properties. I essentially amplified the file within it's limits, reduced some of the noise created by the amplification and then marginally slowed the file making it easier to recognize what is (allegedly) being said. It's common for the pitch and or the speed of the words to be accelerated Thankfully your original file had a fairly clean noise floor.
I've only isolated one section of the audio file. You may not agree with my interpretation but the first part of the two part file I believe was a stomach gurgle either by you or another person present. I've recorded hundreds of hours over the last 13 years and frequently these rather unavoidable entries find their way into audio snippets. This is why I did not include it in my refined sample.

As my controls progressed I quickly added a requirement that all investigators were adequately fed prior to the investigation. Concentration was also minimized during an investigation if an empty stomach wasn't appropriately taken care of. This control or safeguard wasn't foolproof but it reduced the demonic stomach growls. Many of these bodily functions were not observed until we began including dedicated condenser/phantom powered microphones into the equation. On more than one occasion, the equipment was sensitive enough to pick up a investigators heartbeat during a passive audio session.
During my analysis stage, I determined the averaged frequency response for the snippet was 258 Hz. This is within the human range of speech but in the lower frequencies. Humans typically range between 400-8000 Hz during their word formation. That may sound like an extreme but opera singers as an example have a considerable range. The real defining characteristics of EVP/AVP is the extremely flat vocal banding noticeably in the frequency spectral. Your sample made it very easy to make that immediate determination because of its relatively low noise floor and dynamic characteristics.
I have just two suggestions for you if audio becomes a staple for your investigations. I'd recommend buying a recorder that is capable of recording real-time so monitoring can be incorporated into your methodology. In my opinion a shortcoming with many investigations is the lack of this procedure. It's self defeating if you want true communications from both sides. It's the equivalent of dialing someone, asking a question and walking away from the phone. Use a pair of headphones to monitor. I don't believe your sample was aural voice phenomena because of the frequency response but it might have been a missed opportunity if you weren't monitoring real-time. AVP (aural voice phenomena) seems to hold an additional property of frequencies bordering the 100 Hz range. In my research AVP is where you find real time interaction with asking questions or phrased differently, an intelligent response. They are EXCEPTIONALLY rare but they do exist.
My second recommendation is to keep your questions shorter otherwise you can easily have something over-talk on your words. Also try NOT to use questions that volunteer answers with yes or no responses. Include two different types of audio sessions in your investigations, passive & interactive. In passive, I identify my intentions and try to sooth a worrisome entity if intelligent by assuring them my intentions are genuine to help and tell them they have 10 minutes to express themselves. I also include these words before I go into silence. "If there's a message you want to pass on to a loved one, I will do my best to accommodate you".
In the interactive session I usually ask only 5-10 questions (depending) and allow 30 second intervals between. This gives adequate time for the energy manifestation for a response. Interactive sessions should typically last no more than 5 minutes. I've adopted this procedure from the late great Sarah Estep who brought EVP research to North America. She worked with two great EVP pioneers Friedrich Jürgenson & Dr Konstantin Raudive from Europe who I have equal respect for.
I will be posting this on PS's forum as well. I'd appreciate your response on the forum so others know that I've addressed your sample appropriately.
I have looped your snippet three times. I wouldn't over listen to it but this is MY DETERMINATION as to what is being said. Your mileage is likely to vary!
I will be wrapping these words in a spoiler tag to minimize my influence.
Thank you also for providing additional background information. That location is VERY interesting and from what I understand that active place is booked a YEAR in advance because of it's popularity.
