The "Recording type" allow you to set the default file type of recorded files.
The default value is set to "mp3". You can toggle between "wav" and "mp3"
by pressing "Space".
The next three options are used to control the quality of recorded sound.
Higher values in "Sample rate" and "Bitrate"/”Bits per channel” mean a better
quality of recorded sound, as well as a larger file size for recorded files. In
other words, to record high quality sound, the total time the Braille Sense U2
QWERTY can record is shortened. On the other hand, if you lower the
values of these options, the Braille Sense U2 QWERTY can record sound
longer, but the sound quality may not be as good. You can change these
values by pressing "Space". When using “mp3”, “Sample rate” is available
from 16000 Hz to 48000Hz and “Bitrate” value is available from 64K to 320K.
When using “wav”, “Sample rate” value is available from 8000Hz to
44100Hz and “Bits per channel” value is available between 8 bits and 16 bits.
When you record sound using the external microphone, you must set the
recording source to "External Mic". When you record audio using the line-in-
cable, you must set the recording source to "Line in". When you record
sound using internal microphone, set the recording source to "Internal Mic".
The "Set folder" option allows you to set the default folder where the
recorded files are saved. The default value is set to "/flashdisk/media/record".
To specify a different folder, press "Enter" on "Set folder", and a File
Manager-type dialog is displayed. Select a folder as you would in the "Open
Folder" dialog.
Press "Enter" to save your settings, or "Esc" to exit the dialog without saving
your settings.
Note: the following tables show approximate available recording times when
recording at various sample rates using both WAV and MP3. The available
recording time is measured based on a newly formatted, empty flashdisk.
