Digital recorders differ in recording medium and format. Preferred PCM (Pulse Code Modulation format) means that the file is initially changed from analog to digital through measuring portions of the sound and transferring the sound to zeros and ones. This is gathered in '''raw''' form rather than '''compressed.'''PCM is usually saved as a WAV or AIFF file. Digital recorders that save in MP3 or WMA format are compressed and lossy. WAV format is a raw file. The raw file takes more space than the compressed file, lowering the recording time. Many consumers do not understand this when purchasing a digital recorder. | Digital recorders differ in recording medium and format.
