questions about Radionomy
Hey everybody, I just found this free service online called Radionomy. Have any of you ever heard of it or used it? If so, I was just wondering, is it accessible? Is it something that a blind person could use? A friend of mine and I are producing radio shows in the form of podcasts and then he posts them online on his facebook page for everybody to listen to. If the podcasts are successful, we may decide to create a radio station later on in the future. So, I was just wondering about Radionomy and just wanted to see if anyone on the list has ever had any experience with it. Have a good one. Mike Rochester, NY. P.S. Oh and if you want to check out this service for yourselves, you can visit: http://www.radionomy.com/en/static/createradio
Re: Digital audio question
I imagine if you use the digital output jacks, it will send uncompressed digital audio as decoded from the Atrak on the disk. I'm not sure if the Minidisc players convert the sample rate to 44.1 khz when outputting digitally, or if the device at the other end has to support the 32 khz on the disk. - Original Message - From: "Gary Schindler" To: "PC Audio Discussion List" Sent: Sunday, April 06, 2014 9:19 PM Subject: Re: Digital audio question Don, the system is called atrac, which stands for Audio Transform acoustics or something like that. it is near CD quality, 128 KBPS with a sampling rate of 32 kilobytes. - Original Message - From: "Donald L.

Re: Digital audio question
I still use Minidisc but not all that often, as far as I'm aware all Minidisc players and recorders use the Attrac format developed for the Minidisc recorder in the beginning though the format has undergone some changes over 20 years. Even the Sony MD I have which connects to the computer and allows the importing of MP3 files etc doesn't store the files as MP3 on the Minidisc, the files are decoded and then re-encoded into ATTRAC format for the Minidisc to play/Edit so I'd imagine - if you're doing a direct digital copy - the signal will be compressed to the ATTRAC format and the sample rate selection will most likely be automatically selected for you unless otherwise specified by your particular Minidisc model.

Re: Another Set Top Box
How did you get XBMC to work? I thought it doesn't really have any kind of accessible interface to it. Did you have to just get sighted help and then control it with an app of some kind, or how does that work? The Chromecast seems neat though. I believe the device does do its own streaming in the sense that the Chromecast app basically sends stream URL's to it to play and the interface is purely through its apps.

Greetings, I have absolutely no idea what system is being used in the files, DropBox link for which is below, all I can tell you it in the UK A.M stereo has never taken off, I am unaware what, if any serious experiments have been carried out over here. The archive file, link for which is below, contains two .mp3s, one is a report given on the date indicated by the file name, the other, is a recording made of the A.M. stereo service named, in the location indicated,at the time and date specified in the file name. Please be aware the recordings, at a rather low sampling rate, are somewhat over-modulated but ought to give some idea. I know only what is in the recordings therefore cannot make any further comments. I will only leave this file on Dropbox until Thursday next, 2014/04/10 at mid day UK time, as I do not have much disk space left with which to work. File Name: A. M. stereo.zip File Size: 6.23 MB (6,541,248 bytes) DownLoad Link: https://dl.dropboxusercontent.com/u/7644179/A.%20M.%20stereo.zip -- "Patience is a virtue, possess it if you can, seldom found in women, never found in man."

Re: Stereo AM
Thanks Dane. I'm certainly not an expert on the subject, so if you come up with something different, that's fine. I do remember some mention of the Harris system back in the 80s.
