quality equivalent to a music CD.

Sampling frequency
Sampling involves taking a reading of a sound wave (analog signal) at
regular intervals and expressing the height of the wave at each reading in
digitized format (producing a digital signal).
The number of readings taken in one second is called the "sampling
frequency". The larger the value, the closer the reproduced sound is to the
original.
Speaker impedance
This is an AC resistance value, indicated in Ω (ohms). Greater power can
be obtained when this value is smaller.

Bit rate
This expresses the read amount per 1 second of video/audio data
recorded. A larger number means higher sound quality, but also means a
larger file size.
