If we talk about online stream, most stations that I have tried have their stream with a bit rate of 64kbps or lower (asf, mp3, or flv) Only a few of them like WNNS offer 128kbps stream. So, I think it's no point to save the file in a high bit rate if we record it from online stream.

I haven't listened to a show saved in 192 yet though, are there still "pops" at that rate? Deleting the commercials before saving in 192 should still give you a file size under 300 MB, so it should still be OK to trade. I've found out that you do have to delete the commercials before saving in 192 though, otherwise your file size will be over 300 MB.

I've found out that you do have to delete the commercials before saving in 192 though, otherwise your file size will be over 300 MB. With saving the 80's shows at 192kbps after cutting commercials, the time comes out to around 3h 20m, and the size is usually right around 275 kB--and like I mentioned earlier, I start with the WAV file before I cut commercials. As far as bit rate--I definitely notice a difference once you go down to 128kbps. Keep in mind that even though your PC initially receives the show as a digital stream, you are recording from an analog feed by using the headphone out and mic in with a mini to mini plug (different from say, ripping a CD, which is a digital to digital conversion). So there is some loss that will occur in the recording process as the analog audio is re-sampled by your recording software, which is why I think it's not a bad idea to save at a bit rate a little higher than the station's stream. Just my two cents...

Just my two cents... I'm using a software that can capture the digital stream directly from most stations. It doesn't have to get the signal via the sound card. But I got your point. If we record via the sound card, we are recording an analog signal. In this case you may need a higher bit rate to reduce further loss.

I use 192K in audacity also, good quality without large file size.

So...I'm listening to the recording I have of 9/26/87, making sure I didn't miss anything for editing. I discover that in Casey's outro for "I Just Can't Stop Loving You", half the vocal track has been removed (the top bar has sound waves as it should, but the bottom bar is blank, like it's dead air). It wasn't like this the first time when I went through and edited the commercials out. What could have happened? (P.S.: For this show, I need #s 40-37, and a replacement for #19, in stereo. PM me if you have those. )

So...I went back and listened to my recording again, and the "blank audio" problem wasn't there! It's like it was there when I was listening yesterday, but that's it. Huh...

I use Audacity on my Windows 7 laptop with an Intel iCore processor and on my Windows Vista desktop with an AMD dual-core. I don't recall having this particular problem, but it has taken me sometime to learn all the things it can do, how to troubleshoot, etc. Maybe check to make sure the right outputs and inputs are selected? (I made that mistake early on) As far as recording from a stream, this can actually be done all with one machine. You can take the mini-to-mini cable and loop from the headphone/speaker output to the line in/microphone input. The trick there is you have to go into the Windows audio settings under recording devices and properties for whichever input you are using, and turn off/uncheck the box that says "Listen to this device". If you don't do this, your recording will sound like a garbled mess of echos. I would also recommend checking the box that says "Disable all sounds effects" under the Enhancements tab, and turning off all Windows sounds, otherwise during playback you will hear any Windows sounds that occurred while recording. The other negative is that you can't listen while you record, so you have to wait until the recording is done to find out if everything came out okay--however, once you start recording this way you can kind of tell what's going on by watching the blue EKG-like graphic sound wave--at least you can tell if your stream dies, if you are getting dropouts, etc. I haven't had too much trouble with not being able to listen during recording, because I often can't sit and listen anyway and end up listen to the shows in my car or at work. Is there a way to turn off "Windows noises" without turning off all sound entirely?

OK, I found it - once I select Export, I click Options at the dialog box that asks me to save the file. It gives me the choice to go as high as 320! Does higher bit rates increase the file size? I ran into needing the plug-in yesterday, so I downloaded it earlier today. You have to remember, the smaller the file, the more "lossy" it will sound. Here is a good article on the subject: MP3 vs AAC vs FLAC vs CDIt's been my opinion that around 196kbps is a good balance between sound quality and filesize. You have to consider your source, however. If you are getting your music from a stream, a higher bitrate like 196 may be overkill. The stream is broadcasting at 32-128 depending on the station you get it from. You may not notice a difference in quality if you go with 96. If you are getting your source over the air, it may be best to go with something lossless. WAV is lossless, but it's a pretty big file. ACC, WMA, OGG, APE and FLAC all have a lossless codec, and would cut the size of your WAV file 40-50%. Of those, I would look into FLAC.

What about Vista? (Vista's my system... )

What about Vista? (Vista's my system... ) Go into the Sounds menu under Audio Properties on your Control Panel, and select "NONE" for the sounds package/scheme. I did that on both Vista and Windows 7 (it's very similar, especially once you get into the Sounds menu). Now I don't have to worry about the beeps, bells, etc. that Windows makes.
