Re: Decoding SSB OM recorded files

Yes. That should do it. It will never be perfect because you're actually missing one one of the two sidebands as well, but if you need to derive useful intelligence, that should be enough.

Re: Low input level with no control in 1.3.14

Apple > System Preferences > Hardware > Audio > Input.

Do you have good level there on the bouncing blue ball meter and can you change it OK?

Which MacOS?

Re: Decoding SSB OM recorded files

That could do it. You have to put the carrier back in for successful demodulation. Unfortunately, when you do that with the the audio, the carrier would be battery voltage or DC. The "real" voice is the difference between the carrier and the "stuff" we got. So yes, if you beat or...

Re: Exported files are "locked"

I can work around this by reinstalling Audacity Particularly strange since reinstalling Audacity doesn't reinstall Audacity. This is where rich detail comes in handy. "I'm having trouble exporting MP3 files from my Windows 7 GateWay Dimension... that I've owned for three days .. When I recorde...

Re: Decoding SSB OM recorded files

Single Side Band, Suppressed Carrier transmission. AM radio takes up a lot of room on the dial and if you do the math, most of it is duplicated or wasted. HAM radio operators aren't bothered by messy broadcast standards, so they quickly figured out how to suppress the parts that "weren't needed...

Re: 44.1khz, 48khz or 96khz

Of course it's best if you had done all the work at the higher bit rates and depths. Whatever sound damage you have is already burned into the music. These are examples: Depth/Rate Conversion -- Change Project Rate (Hz) lower left > 44100 -- Track Name > Set Sample Format > 16-bit PCM Music CD is 41...

Re: No sound in itunes

While the music is in your music folder, Control-Click on it > Open With > QuickTime Player. See if it lasts any longer there. Also, Press Command-I to get the INFO panel. It might look something like below. Then Shift-Command-4 and draw a box around the INFO panel. The Mac should give you a Screen ...

Re: Is it possible to simultaneously record and playback?

Yes, no problem in Audacity 1.3, but it may not be possible to perfectly make the computer do it. Which delay have you got? The one where you sing in perfect time but it plays out of time is easy. That one's Recording Latency, and it's a setting in Audacity 1.3. If you expect to hear yourself in you...

Re: How record with 2 mics?

No. Nobody makes this. http://kozco.com/tech/audacity/pix/headsetBattery.jpg That's the one that I made to interface with an XLR mixer. I used four 1.5v batteries for a total of just over 6 volts instead of the computer 5 volts, so it's slightly louder. The microphone in an analog headset is a "...
