Voice Pad - HandEra 330 User Manual

Voice Pad

Voice Pad is an application that can record and play back
audio messages. Voice Pad functions like a digital tape
recorder or dictation machine. The number of messages
you can store is dependent only on the memory available
in your handheld computer or in one of the expansion
slots.
Voice Pad uses the sound format commonly used with Microsoft
Windows, waveform audio. Waveform filenames include the .WAV
extension. The waveform refers to the vibrations associated with
translating sound into electric current. The amplitude of the
waveform is its loudness. The frequency is the pitch.

Voice Pad supports the recording of waveform audio files with a
sampling rate of 8 KHz. The sampling rate refers to the maximum
frequency of sound that can be digitized for a given sample. The
sampling size for waveform audio files is 8-bit mono. The size
determines the dynamic range of a sample.
