I have recently bought two digital sound machines by MRC. The City & Country Sound Station that has a varity of everday sounds form rain, roosters and cows, jackhammers to trafic, thunder and rain & running water to name but a few. I like to set it for the forest sound or the running brook to sleep with at night. The other gem is the MRC Synchrony Sound for steam which as as many sound as Lionel's TMCC. I will give you a report on that later. They make one for Diesels I haven't bought yet. The City & sound has stereo speaper and a wired remote. The volume is high but at the max level there is some distortion. Most sounds like the car crash and car horn last I few seconds but several other once the key is pressed continue one. For example you can have continuance traffic then a brief car brake, horn blow and crash all with in two seconds. Everyone that has heard that get a kick out of it. Nature sound work the same way with forest sound, bugs and rain. I am going to test the steam sound gizzmo here in a bit.
