Just a little note. The DTG headquartres is cornered by three Southeastern stations. So the expectation of the sound quality for these EMUs is higher. You can buy from AP if DTG thinks it is easier. But the Class 375 cannot be reusing the sounds from ECW. This is TSW2 and TSW2 means upgrades. The Talent 2 got a sound overhall for SKA, the Electrostar needs a sound overhall for SEHS. Like I said, the DTG HQ is cornered by three SE stations. So DTG has a lot of Electrostars to get sounds from. I recently implemented recorded sounds for the Class 377/4 and it significantly increased the sound quality for the train, and made the whole DLC much more playable. I only set aside an afternoon to go and get those sounds, and I travelled 30 miles to get them. DTG is lucky that they have multiple Electrostar-served stations in the area. The Class 465 Metcam variants are also close to DTG. So, if DTG records it themselves or buys it from AP, good show. If it's synthesised, the criticism is gonna rocket through the roof and into space. So to reiterate, there's little excuse for bad sound quality on the Electrostar 375s and 465s.
