Insects time stretched

This patch of unpromising looking waste ground next to a main road hosted a number of crickets – probably bush crickets by the sound through the bat detector compared with some on the web, but heck, what do I know, they could be something else.
Anyway, lots of these guys, and they sound a lot better to me reconverted and time-stretched

than the original recording which sounds like mush to me

Once again, detail seems clearer in the time stretched recording. The tone colour and character of the time stretched recording is much more recognisable as related to the audible sound, recorded with a standard MKE300 microphone (with traffic noise and people – this was a busy road)
