We're using a passive direct box that's supposed to have a hi-Z input, but it doesn't say how high. She has a volume pedal with a 250k pot, which she used for a while and then took out. If the load imp were low (dynamic mic range), all the control range would be squeezed into the top end of the pot,...

My wife plays violin, and she uses a bridge pickup. To me, the sound is unnatural - I'd call it all string and no body. I've been faking it on the board by adding a peak around 400 Hz. This seems to give the closest sound to what I get from a regular mic at close range with no other sounds to interf...

Subharmonics can also be a problem in switching power supplies. Bull's Eye! That's what I was designing when I encountered the inductor problem. It happened in the Spice model and on the breadboard. Control loop instability can cause it too, but in this case Spice showed it happens even with the lo...

I was so intrigued by the spectrum consisting entirely of multiples of 100 Hz that I put some effort into the problem. What I should have noticed right off is that 100 Hz is the largest common factor of 10 kHz, its harmonics and the sampling frequency, so any result consisting of differences and mul...

Good question! It's easy to do the experiment. Use Generate->Tone->Sine and clip the result by any means you wish. Just amplify (allow clipping) and Analyze->Plot Spectrum still shows only the single spectral line at 10 KHz. But Amplify again knows that the amplitude is already 3 dB above clipping, ...

On the occasion when I got it out of mode 3 (no auto scrolling), I used Shift-Ctrl-A to deselect everything. But it seems that doesn't always do the trick either, and now I'm not even sure whether it had anything to do with getting out of mode 3. I haven't found a way to predict which mode it will b...

I note 3 modes of waveform display scrolling while recording: 1: When cursor reaches end of screen, tracks jump back a couple of inches; 2: When cursor reaches end of screen, tracks jump back full screen width; 3: No automatic scrolling but manual scrolling still works. When in mode 3, I managed to ...

Pop Mute is a real time saver. I record church services for CD and podcast, and we have a couple of people who can't remember not to clap in front of a mic. I fade out the mic, but not before I've got a string of spikes in the recording. With this tool I can squash the whole string in one operation ...

I think if both copies are about the same amplitude I'd call it a chorus effect.

Furthermore you lose any clips, envelopes, etc. you have in your uncompressed project. I was wondering about clips, especially if they're far apart - does the gap between get encoded as silence and still take up space? But losing the envelopes, now that's a surprise :shock:. Isn't the envelope (alo...
