Recording formats (compression/decompression and stereo/mono)

The DN-F20R offers a choice of three recording compression/decompression formats (linear PCM, MPEG1 Layer 2, and MPEG2 Layer 2 LSF –

see below) and the choice of stereo or monaural recording.

2 Linear PCM

Recording is performed without compression, with a sampling frequency of 48 kHz and a quantization bit number of 16 bits.

This recording format offers the maximum sound quality possible on the DN-F20R, but the quantity of data per unit time is large, so it uses

up much card space.

Because the quantity of data per unit time is large, the card access speed must be high. Recording in linear PCM may not be possible on

IC memory cards with small cluster sizes and capacities of 16 MB or less. If recording is not possible, either recording will stop or an error

message will be displayed when recording starts.

2 MPEG1 Layer 2

Recording is performed with a sampling frequency of 48 kHz and a quantization bit number of 16 bits, but with compression, so that the

quantity of data is about 1/6 to 1/12 that of linear PCM recordings.

With this mode, the card space can be used efficiently.

2 MPEG2 Layer 2 LSF (Low Sampling Frequency)

Recording is performed with a sampling frequency of 24 kHz, a quantization bit number of 16 bits, and compression achieving a data quantity

of between about 1/12 to 1/48 that of linear PCM recordings.

Because the quantity of data per unit time is small, the frequency response is set to about 11 kHz, reducing the frequency band of the

compressed data to maintain sound quality. With this mode, the card space can be used at its highest efficiency.

2 Stereo/monaural

Stereo or monaural recording can be selected for all three compression/decompression formats. With monaural recording, the file size is half

that of stereo recordings.
