Please name your files appropriately (ie - ChosenSpokes_April2023_sideA), and send each side as one single track.

Uncompressed formats are always preferred to maximize the qualities of your cut (WAV, AIFF, etc).

Mastering for cutting is included in your quote. Low end frequencies should be mixed in the middle and excessively sharp high end sounds (hi hats, vocal sibilance, etc) should be contained.
