Encoder Options for MPC Files
MPC (.mpc) is the extension of Musepack files. Musepack is a lossy format which aims for high compression and no discernible loss of quality.
This setting defines what level of compression the encoder should use. The options range from Thumb through to Insane. Thumb provides high compression at the expense of quality while the Insane setting focuses mainly on retaining quality rather than high compression. The default option here is Standard (High Quality).
