  • Page 15 Recording Formats 1. WAVF32 32-bit float WAV Lossless, maximum quality recording format.

This process is called normalization, and can be accomplished with a variety of programs. 2.

This can be useful for voice recordings where the speaker may change in distance from the mic, such as meetings or lectures. 2.
