The Audio Restoration Tools portion of the Wizard displays tools that clean up or enhance the audio recording.
You can play a file by double-clicking it before applying any of the restoration tools. Use it to test the sound of your files before moving on to the next wizard step.
DC Offset Correction
Often, when you record audio using bad electronics the recording has a constant 'DC' level throughout the file. Because the ear cannot hear this, you will not notice it until you attempt to edit in other audio, and then you can hear horrible clicks. Use the DC offset tool if you think you might be subject to this problem.
The high-pass filter in Golden Records keeps all frequencies in the audio above 150Hz. This is useful if you want to make your recording sound clearer or less 'muddy'.
This tool applies only to recording from vinyl records. When music is recorded onto vinyl, the tonal qualities of the music are changed in order to minimize the groove widths and fit more audio onto the LP. So basically, the bass is reduced and the treble gets amplified. When you connect your player to an amplifier and play a record, you will not hear this effect because your amplifier has in-built electronics to reverse the change that the music was subjected to. This tool is designed to do exactly what an amplifier's electronics does. If you are not in a position to connect your record player to your computer through an amplifier, you must use this tool, or else your audio will sound very radio-like in its quality.
Auto Click/Pop Reduction
This tool is designed to remove click and pop sounds from recordings. It is designed mainly for the recording from vinyl to CD/Wave/MP3 process, with the intention of repairing defects caused by dust and scratches on the vinyl.
This tool is designed to remove background hisses and hums. It does this by using multi-band noise gates to turn off bands that are below a preset volume level, in this case, around -30dB.
This adjusts the volume levels of your audio to ensure that your recorded files are never too soft or too loud. It will ensure that all recordings are at a similar volume level with respect to each other.
This will apply the selected Audio Restoration Tools to all files in the list.
This will undo all changes you have made to the sounds and restore to the oringinal recorded sound.
