Hint:
· What is Linear PCM (Pulse Code Modulation) recording?
Linear PCM (LPCM) recording is a digital recording method that samples analog audio
signals at a certain frequency and saves them as digital signals without compression.
Music CDs (CD-DA–CD digital Audio) use PCM recording (sampling rate of 44.1kHz, bit
depth of 16-bit samples, bit rate of 1,411kbps, and frequency response from 20 to
20kHz).
PCM recordings are digitally-recorded unprocessed audio, and are supposed to be of the
highest sound quality. "WAVE" format is used to import these PCM recording files into a
computer. The WAVE file extension is ".WAV". MP3 and WMA format files are created
by compressing the LPCM data.
· Recording margin indicator
Recording margin: space or margin (expressed in dB) between 0dB and the input peak
levels.
