Useful information
• 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
20,000Hz). 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.
• What is recording margin?
Recording margin is the space (margin) expressed in dB between 0dB and the most
recent maximum input volume.
