This option enables and disables resampling, described below.
In general, "resampling" is a term used to refer to a systematic conversion of audio data from one sample rate to another.
The digital audio data read from the CD is in stereo (two channels).
Enabling "mono" converts the audio data to monophonic (one channel) before encoding.
This makes the audio data half the size as normal, but of course you lose the stereo separation.
This process of combining the two stereo channels into a single mono channel is also known as "channel merging."
Allows you to choose the target sample rate.
Data on an audio CD is stored at a rate of 44,100Hz.
If you resample to, say, 22,050Hz, the data will be half the size because only half the information is used, but the aurual quality will be reduced, especially at higher frequencies.
For example, you will notice that at lower sample rates, symbol crashes will sound less "sharp."
An analogy for graphic images would be changing the image resolution.
For example, if you start with a 100x100 pixel image and reduce it to 50x50, the file is smaller but less detailed.
Allows you to select the interpolation method used during resampling.
(Usually you won't need to adjust this.)
This refers to how to interpret target resample points that occur between source sample points.
Using sinusoidal interpolation treats the audio data as a curved shape, with smooth peaks and valleys, while linear interpolation treats the audio data as having an almost "triangular" shape with sharply pointed peaks and valleys.
The Resample Options may be shown or hidden via the View Menu.
