![]() Human hearing would need a reduction of -18 dB to make audio "appear to sound" half as loud. Halving the volume on the linear scale (for example, deamplifying a sound with a peak of +/- 1.0 by -6 dB to bring it to +/- 0.5 on that scale) does not sound all that much quieter. However, the linear waveform does not correspond to the way your ears work-they sense quiet sounds more effectively. When zoomed in edit points are easy to find. The default linear Waveform view is very convenient for editing since the majority of audible work is on the screen. The waveform view can be switched to a dB logarithmic view by right-clicking on the track's Vertical Scale and selecting " dB" from the dropdown context menu. The horizontal center line denoting zero amplitude (silence) can also now be clearly seen, with positive samples above the center line, and negative samples below. The waveform can now be clearly seen as joining together many individual sample points (the dots). The line you see now represents the peak level of the samples, that is the top of the darker part that you saw when you were zoomed out.īelow is an example of a dark blue only waveform, obtained by zooming in about 12 times. If you zoom in horizontally far enough, the light blue display will disappear, because there are not enough samples to provide a meaningful average in the region being displayed. This is a rough guide to how loud this area might sound, but there is no way to extract or use this RMS part of the waveform separately. The light blue part of the waveform displays the average RMS (Root Mean Square) value for the same group of samples.At default zoom level Audacity will display many samples within that pixel width, so this pixel represents the value of the loudest sample in the group. The dark blue part of the waveform displays the tallest peak in the area that pixel represents.Subtle Air & Bass boosters to lift and help the audio 'breath'.The waveform view uses two shades of blue, one darker and one lighter. Stereo width slider going from mono to wide, bringing the stereo image out and towards the listener. Loudness control enables a complex saturator to boost your mixes. Try and keep the levels so the white flashes only occasionally, this enables the loudness saturator to work at its best. The main 'bubble' display on the plug-in is really a basic meter, when one of the stereo halves flash white, then the output is in danger of being clipped. These stages create an overall loudness effect on the final output, so a gain control is included to keep the limits in check. This saturation gives the mix a more perceived loudness, without clipping. This also has a mono setting, useful for squashing up those aggressive samples that take over the mix.Ī loudness button that raises the waveform to the limits in a smooth curve. At extreme levels other characteristics are also brought out of the sound, so this can also be used as a tonal control for individual instruments. UpStereo is a simple, useful tool to make your mixes bigger, in stereo width and loudness.Ī fixed frequency EQ designed to lift the highest audio frequencies, and boost the bass.Ī stereo width unit, for expanding stereo sounds so they appear wider and fatter.
