@Chris:
Is there some way to make the Spectrum Display show the same amplitude waveform when recording as it does when in playback?

Pete

Thanks Chris.

When I set Goldwave up to record the audio on my PC's line-input, the spectrogram display seems to smear. In the image below, I am monitoring the WWV time station. The vertical lines are the "ticks" which occur each second. The first four seconds of the display on the left is the output wi...

If there is a system restore point just before the automatic update was done, I would do a restore to that point. Once the system is restored and rebooted, the system update will be done again but this time not while you are recording.

Your suggestion appears to not work with the VEC Infinity pedal, which is a USB pedal I discovered just yesterday afternoon that, unfortunately, not all USB pedals look like a joystick. Some of them look like a serial port and instead of opening a joystick port, Goldwave would have to handle a COM ...

@Tamara: The setup screen I described in my previous message allows you to select one pedal for play/pause, one for rewind and one for fast forward. The rewind is active while you hold down the pedal and isn't fast so it's easy to make it go back a few seconds.

Pete

it does not appear to work with the Infinity USB foot pedals Have you tried to configure Goldwave to use the pedal? A lot of those foot pedals emulate a 2 button joystick controller interface where the play pedal sets both buttons 1 and 2, reverse is button 1 and (fast) forward is button 2. I set u...

I looked at the spectrum of the click in 4.mp3. It is not just a high frequency click (which could be removed with a low-pass filter). It also has strong frequency components throughout the normal speech band (up to about 4kHz) which will make it very difficult to remove without having a significant...

P.S. This is herbert after a 3000-4000Hz bandstop filter with steepness 10 has been applied.

The whistling "S" is obviously a higher frequency than most other speech sounds so if you can identify a frequency range which corresponds to that sound you can filter it out. I have Goldwave configured so that it always starts up with the FFT spectrum showing as well (I forget how you sel...

I had a look at the FFT spectrum of Herbert's whistling. The frequency of the "S" appears to be in the range 3000-4000Hz so I applied a bandstop filter with steepness 10 and it seems to knock out the worst of the whistle without affecting the intelligibility of the result. Play around with...

I played with the options described by Chris and setting "joint stereo" while leaving the quality at high produces a better sounding file.

Pete

I can hear the problem in your mp3 versions.
I loaded the wav file and saved it as Layer-3 ACM, 44100kHz, 128kbps, joint stereo and the result sounds much better than the other mp3 files.
The Fraunhofer ACM MPEG encoder was already installed on my system (Win XP Pro 32-bit).

Clever!!

then filtering out the lower sideband. However, in doing so, I'm losing quite a bit of my signal's low frequency information. Just how low a frequency do you need? This will determine how sharp the filter needs to be to filter the lower sideband and carrier but leave the upper sideband unaffected. ...
