The three options are used to control the quality of recorded sound.
Higher values in "Sample rate", "Bitrate" and "Bits per channel" means a
better quality of recorded sound, as well as a larger file size of recorded
files. In other words, if you want to record high quality sound, the total
time the Braille Sense U2 can record will be shortened. On the other
hand, if you set the lower values of these options, the Braille Sense U2
can record sound longer, although the sound quality may not be as good
as when these options are set to higher values. You can change these
values by pressing "Space."
Below are available options:
- Sample rate: 16000Hz, 22050Hz, 24000Hz (mp3)
- Bitrate: 64k, 80k, 96k, 112k,128k,160k
- Bits per channel:8 bits, 16 bits
Also "Preset" option allows you to choose "Stereo" or "Mono" as
recording type.
