Whether everything he speculates is true or not, i can't say, but some of it is very interesting and surely possible. It reminds me of comments in the transcripts about those old stones found in Scotland that sound out a certain tone when struck (and were used for healing?) and a video i saw regarding the old temples in China which were built to sway in a particular way so as to withstand powerful earthquakes.
Since it is helpful to provide a brief summary when posting a video, what i gathered from the 10 minute video was:
The presenter visits various 'megalithic' sites for his YT channel and reports his findings.
There are a number of temples in India which show evidence of high technology. He thinks this because certain stone pillars within the Vitala complex make specific sounds when struck - there's evidence sandalwood sticks were used. The sounds made, he says, are representative of the 7 note Indian musical scale. The stone pillars themselves may have been modified by melting the stone and mixing them with metals to create certain notes.
One of these pillars was stolen by the British.
He says that within the temple complex itself there are cymatic symbols embedded within the stone carvings.
In one circular image women are seen striking the pillars creating a sound and in the centre of the circle the cymatic pattern they're creating is depicted.
On the roof edges and corners at more than one site, there are granite hoops and sandstone 'chains' that hang from the edges and corners; he shows images of them still existing today on other temples though on the one he is mainly discussing they were apparently destroyed by invaders, along with a tower style complex. He speculates that using primitive tools carving these stones into chain link chains would have been impossible and still can't be done today.
There is a room apparently dedicated to Vittala which has no windows and a large cymatic pattern depicted.

The musical pillars at the Vijaya Vittala Temple
Hampi Vittala Temple
Situated northeast of Hampi, opposite the village of Anegondi, this is one of the principal monuments of the city. It is dedicated to Vittala, an aspect of Vishnu worshipped in the Maratha country. It is believed to date from the 16th century.
In front of the temple is the world-famous stone chariot or ratha. This is one of the three famous stone chariots in India, the other two being in Konark and Mahabalipuram. The wheels of the ratha can be rotated but the government cemented them to avoid the damage caused by the visitors.
One of the notable features of the Vittala Temple is the musical pillars. Each of the pillars that support the roof of the main temple is supported by a pillar representing a musical instrument, and is constructed as 7 minor pillars arranged around a main pillar. These 7 pillars, when struck, emanate the 7 notes from the representative instrument, varying in sound quality based on whether it represents a wind, string or percussion instrument.
The British wanted to check the reason behind this wonder and so they had cut two pillars to check anything was there inside the pillars that was producing the sound. They had found nothing but hollow pillars.Even today we can see those pillars cut by the British.
The road leading to the temple was once a market where the horses were traded. Even today we can see the ruins of the market on both the sides of the road. The temple contains the images of foreigners like Persians selling horses.
The temple is the venue of the annual Purandaradasa festival.
