I can't reproduce the static effect, so the best I can do is post the actual static clip. It's a mono WAV file just under 10 seconds. http://kozco.com/tech/audacity/clips/AMStatic5.wav Loop it if you need more. I'll continue to try and remember how I got there. There's no trouble at all creating a ...

So, has any one noticed the can-like sound I've been talking about? No? I must be paranoid then... I've been able to analyse Ian's tests shortly. What strikes me the most is the extreme presence of frequencies around 1 kHz and to a lesser degree the damped frequencies above. I've radically corrected...

How are we measuring ACX Compliance? I see through searching that we seemed to have settled on WaveStats. http://forum.audacityteam.org/viewtopic.php?p=99454#p99454 I also see that WaveStats uses the "A" curve for RMS noise (normally pretty common). That's at variance with ACX specs which...

It might be helpful to see how white noise is modified after a pass through the whole recording system. I've prepared a test file that you can play as input to the microphone (with some kind of playback system of course). Spectral-test-patterns.flac It includes: - Impulse train - repeated sweeps, 1...

Robert, is this canny sound posdibly a defect of my De-Clicker or did you think it was there before Ian used it? I am not now in a place where I can hear for myself. As I said, I hear it in each sample file, your tool is perfectly innocent in this respect. It might be due to the anti-resonator pads...

If you look back in this thread, there was advice from both Steve and Koz on the Limiter and I now use Steve's Limiter. As for the compressor, I was before these two started teaching me but not anymore. The less we can do to our voices the better is the main lesson I've learnt from them. :) Cheers....

When in doubt, take AM radio, it is the type that every one can build a receiver for in MacGyver style; the novel gives me the impression that all takes place in a after-big-disaster world. Thus equipment is difficult to obtain.

But this does only work for monophonic sounds with a stationary pitch, doesn't it?
You should instead use something like auto-tune, where you can adjust the cent slider for each note.

Thanks guys. Im new to this stuff, so thats why FFT came up as the logical means for getting the frequencies for DTMF decoding. A most natural way of thinking. In this special case, FFT has its draw-backs. Firstly, there are only 8, mostly stationary signals involved and FFT returns perhaps 2048 bi...

Duplicate the track, apply the noise gate and invert one track, this should you give back the suppressed low-volume sounds. The lookahead might interfere with that though.
