Description
Sampling frequency (sampling
rate) [
Hz/kHz
]
The rate or frequency at which an analogue signal is analyzed to determine
acoustic delicacies. The higher sampling frequency produces less difference in
forward/backward sounds.
Quantization bits [bit depth][
bit
]
The number of quantization bits helps determine how much data is required
to save a record when digitizing analog signals (such as voice).
Bit rate [
kbps
]
A Bit Rate indicates how many data bits are transmitted per second.A 128 kbps
file, for example, uses 128 kbits per second to encode data. The smaller the bit
rate you select, the worse the quality, and the smaller the size it will output. The
sound quality varies depending on digital audio compression algorithms (such as
MP3 and WMA), even if the bit rates are the same.Even if the bit rates are the same,
sound quality varies depending on the digital audio compression algorithm (such
as MP3).
Linear PCM format
A linear PCM format is used so that no data gets lost due to compression and
original sound stays intact.This format is used for music CDs (CD-DA).
MP3 format
This is one of the most popular digital audio compression algorithms. It achieves a
compression factor of about twelve while preserving sound quality.
Memory (media)
This is a storage system that does not lose the data stored on it even when the
power is removed. In this manual, it refers to the built-in flash memory and the SD
card.
Encoding
Encoding is a process in which the information obtained from a source is
converted into data according to certain rules. Or it is a process in which data is
converted from one format to another (such as audio compression) according to
certain rules.
