For intelligibility of the voice, to boost slightly the 2000-3000 Hz range helps to get some hissing consonnants(f, t s, z). But boost too much should be an annoyance. If the sound comes already from a telephone quality, the best is to do nothing or to set the sound case-by-case, because the receive...

When I studied for my amateur radio licence, the standards we knew (from the French Telecommunication laws) were 0.775V for the voltage, and the authorized bandwidth was 300 Hz to 3000 Hz. Butn, by now, with the generalization of digital signals, things may have evoluted. In other circumstances, I r...

Maybe the «Shape Volume», that will be the quickest way.
If the slope isn't coarse enough, you can try otherwise so:
VIEW > Specify
EDIT > SELECT VIEW; EDIT > Mute ; CTRL+A ; click twice on the bar at the bottom to scroll to next view and the next view again; EDIT > Mute, and so on.

It is common that a database have not a CD listed. The Cd's are listed depending of the infos sent by the users. If a CD is missing, it means that nobody before sent them. The logical way to act is to fill them with exactitude and submit in sort that they can be taken in account for next users. Thes...

The limiter is in fact the compressor (the button with two pairs if vertical arrows in opposite direction). The distorsions cannot be much reduced. You should try to use the low pass filter at 5 kHz, but that will have few effect on the distorsion. The ideal is to avoid overloads from start, because...

Preferably connect the Line Out of the tape recorder to the line in of the computer (blue).
If your tape player has no line output, you should try, carefully with the volume adjustment, to use the headphone output, but the quality loss will be perceptible comparatively to a true line output.

It is possible to use the view selection for that.

1 • View | Specify | 9.0 second
2 • CTRL+W (will select the visible part on the screen)

I listened to it through iTunes Music Store. What Dougbug said is right, however, I warn you that the algorhythm which preserves tempo is time consuming, but trying to speed the process lowers the quality significantly. Optional! Another thing I heard is the acoustic: on "Technologic" ther...

Have you another driver on your computer? I had some problems with unexpected setting changes with my soundboard. In fact, the re-installation of XP have been made over the previous one for another mainboard and processor, and the old drivers were not completely removed. After a clean re-installment...

1) Volume levelling : The GW voice fx plug-in can equalize the volume all along a file or a selesction. Another possibility is the compressor-limiter, but it doesn't work as well on this situation. 3) Statics can be reduced with the function pops/clicks, then the smoother, and the hiss can be reduce...

You should try to change the playback rate, and then resample to a standard sampling rate. But your audio will probably be muffled.

For voice, I think that you better save as a mono file, and that you can reduce the sample rate to 22050 kHz: so, you will get the quarter of the bitrate which would have given you the same quality in 44100Hz stereo. If you filter frequencies under 100 Hz (the value can vary depending on the voice, ...

The possibilities to reduce it: If the level of this echoe is low enough, you can attempt to use a noise gate in the compressor limiter efftec, adjusting the settings with the slides. If the delay of this echo is short enough: To hide it, get a stereo file from the sound, do a second workign copy(CT...

The lowpass/highpass/bandpass/bandcut filter generates indeed a click at start if the slope is set on another value than 5. Before to apply it, to have the click out of the sound you will use, you might add on esecond of silence at beginning, this second of silence will be thrown away once the filte...

Before you select your section, verify that "Edit|Markers" is set to "snap to zero crossing". If you get a click/pop problem at beginning (that can occur with the low/high/pass/cut-band filters), my suggestion before to apply these filters is to copy and paste as new sound, and a...
