Re: Piano recording -> sound distortion ?

Two problems. If you're recording the Line-Out or Headphone Out of your keyboard, they're both too powerful for the Mic-In of your Windows Laptop. In addition, Mic-In is usually mono, not stereo. If that's not how you're recording the music, then we can go to step two. Windows naturally assumes you'...

Re: getting signal from USB Mixer

It's step one or step two of the Audacity Overdubbing tutorial is that you get your system to do a straight recording before you get complicated. Can you do that? Sing into the microphone and record it in Audacity? Important step, can you play it back through your mixer after you made the recording?...

Re: Waveform under the line

Earlier analog sound systems were immune to this problem, so it was a nasty surprise when those of us who work in both found that digital would cheerfully record waves and signals that were not sound at all. And yes, it's perfectly possible to have one computer do this and the other not. The one wit...

Re: Playback on one speaker

We wrote a thing on overdubbing and sound-on-sound. http://manual.audacityteam.org/o/man/tutorial_recording_multi_track_overdubs.html Almost all performances like this are on headphones to avoid feedback and odd problems, but if you have no microphones in the system, you can go with speakers. The pr...

Re: Waveform under the line

Yes. That's DC Offset. That's a very tiny piece of the battery or computer power supply getting into your show by accident. You can't hear it, but it can cause editing nightmares. If you use an analog microphone (not USB) then producing a digital signal for the computer depends on the sound card or ...

Re: Newbie Encoding Question

Converting an MP3 to WAV or AIFF perfectly preserves music and the sound damage from the original MP3. When you make another MP3 from the WAV, the MP3 encoding process converts the music plus the original damage. Nice try though. And a word on the damage. It's not like the sound is suddenly going to...

Re: Lengthening an aiff file

linear cpm It's PCM. Pulse Code Modulation. I have a sound file Another hole. Where did you get the sound files from? Your system may just refuse to play any sound under certain conditions. Audacity converts music to its own internal format and then creates a whole new file on export, so now you kn...

Re: HOW TO RECORD A MAGIC JACK PHONE CALL USING THE PHONE

Now I know this can be done switching to headset, but I do not want to that: it is cumbersome. You know that because you personally got it to work, or you know that because somebody said so? Recording a Voice Over IP phone call correctly usually requires specialized software that "knows" ...

Re: Lengthening an aiff file

when I play it from my program on the iPad Don't gloss over important information. Which program? (tock.aiff, it is the "tock" sound when you press a key on the iPad) that is playing fine in iTunes. iTunes where? You can, if you're on a MacBook or larger computer, open the file in QuickTi...
