MP3 Bit Rate
The 688 records MP3 files at a default bit rate of 320kbs, but that bit rate may
be changed. A high bit rate MP3 file preserves more audio information with an
increased file size. A low bit rate MP3 file preserves less audio information with
a decreased file size.
To change the MP3 bit rate:
1. Press the MENU button.
2. Turn and press the Headphone encoder to select RECORDER > MP3 Bit
Rate.
3. Turn and press the Headphone encoder to select a bit rate. Options include:
128, 192, and 320 kbs.
Sample Rate
The 688 records WAV files at 48 kHz sample rate by default.
To set sample rate:
1. Press the MENU button.
2. Turn and press the Headphone encoder to select RECORDER > Sample Rate.
3. Turn and press the Headphone encoder to select a sample rate. Options include: 44.1k, 47.952k, 47.952kF, 48k, 48.048k, 48.048kF, 88.2k, 96k, and
192k.
The sample rate value is stored in file metadata. Those options with “F” are
F mode rates. The F stands for “faux” or “Fostex”.
