Here are three Nyquist plug-ins for unsplit stereo tracks:
For a mono track, here is a keyboard-only work-around.
- Have a mono sound open in Audacity and ensure it has focus using UP or DOWN arrow.
- Open the Track Dropdown Menu with SHIFT + M.
- Press 'l'. This will move the audio to the left channel.
- Select all using CONTROL + A.
- Open the Effect menu with ALT + C.
- Press 'n' until you get to "Nyquist prompt".
- In the edit box, type (mult s 0.8) (the number should be between 0 and 1). The higher the number, the louder the signal will be. It's a linear not dB number. 'Mult' means multiply the audio s by the given number. 0 will reduce the volume to zero, 1 will create no change, something above 1 will increase the volume.
- Export the file as WAV using CTRL + SHIFT + E, hit the enter key, type the name of the file and click on the 'save' button. (You may need to specify the folder).
- Press control-z twice to undo the amplification (mult) and channel-select jobs;
- Repeat the above steps 2 through 9, except choose 'r' to move the audio to the right channel, and use a number which is different to the first number.
- Press CONTROL + SHIFT + I to import the WAV file you first exported (which is in the left channel. Type the name of the file you saved in the edit box. You may need to type the folder too).
- The audio will be somewhere in the stereo field between the far left and far right channels. Using the example numbers, the audio will sound somewhere left of center.
You'll probably need to do some experimenting to get the desired panning placement just where you want it.
