The Spectral-Gain.ny plugin is an Audacity plugin that allows users to apply gain changes to their audio tracks. It can be used to adjust the volume of a track, or to boost certain frequencies in the track. The plugin allows users to set the gain value in decibels, as well as set a low and high frequency range for the gain change. When the plugin is applied to the track, it will apply a gain change across the specified frequency range, and ensure that the gain change is applied smoothly across the entire range.
The Spectral-Gain.ny plugin is an Audacity plugin that allows users to apply a gain to a sound. It is designed to work with sounds that have a frequency range between 1 Hz and half of the sample rate of the track. The plugin uses Nyquist, a powerful programming language, to apply a low-pass and high-pass filter to the sound, before applying the gain. The low-pass and high-pass filters are generated using a sinc filter, which is a type of windowed sinc filter, and a blackman window. The gain is applied using a piecewise linear envelope, which allows the user to specify the gain at different points in the sound. The plugin also provides a control to set the fade time, which is the time it takes to transition from the gain set at the start of the sound to the gain set at the end of the sound. This allows for a smoother transition between the two gains. With these controls, users can easily apply a gain to a sound with a specified frequency range and a smooth transition.
To increase the volume of a specific frequency range in Audacity, you can use the Spectral Gain plugin. To do this, open your desired track in Audacity, select the frequency range you wish to increase the volume of, then navigate to Effect > Spectral Gain. In the Spectral Gain window, enter the desired gain in dB and click OK. Your track will now have an increased volume in the specified frequency range.
To create a Low Pass Filter, open your audio file in Audacity. Then, select the Spectral Gain plugin from the Effect menu. The plugin will open with a control labeled “Gain (dB)”. Set this control to the desired gain value. Then, select the frequency range for the low pass filter by selecting the start and end frequencies in the selection. Finally, click “OK” to apply the filter. The audio file will now have a low pass filter applied with the gain value set by the user.
To create a High Pass Filter in Audacity, open the Spectral Gain plugin. Enter the desired gain value in dB in the "Gain (dB)" field. Then, select the frequency range you want to apply the filter to in the track. Click the "Preview" button to preview the effect and the "OK" button to apply the effect.
To create a band pass filter in Audacity, first select the audio track you wish to apply the filter to. Next, open the Spectral Gain plugin from the Effect menu. In the "Gain (dB)" field, enter the desired gain in decibels. Then, set the low and high frequency values to the desired range. Finally, click the "OK" button to apply the filter.
Example 5: Notch Filter To use the Notch Filter in Audacity, you will need to open the Spectral Gain plugin. To do this, go to the Effects menu and select Spectral Gain. In the Spectral Gain window, set the Gain (dB) to 0. This will set the filter to a Notch Filter. You can then adjust the Low and High frequencies to adjust the range of the filter. Once you have adjusted the range, click OK to apply the filter.
