Kebetulan gwa lagi skripsi tentang suara.

KHz itu jumlah sample suara yang diambil setiap detiknya, makin tinggi berarti makin detil.
Dari wiki : “The sampling rate, sample rate, or sampling frequency defines the number of samples per second (or per other unit) taken from a continuous signal to make a discrete signal. For time-domain signals, it can be measured in hertz (Hz). The inverse of the sampling frequency is the sampling period or sampling interval, which is the time between samples.”

“In digital audio, common sampling rates are:

* 8,000 Hz - telephone, adequate for human speech
* 11,025 Hz
* 22,050 Hz - radio
* 32,000 Hz - miniDV digital video camcorder, DAT (LP mode)
* 44,100 Hz - audio CD, also most commonly used with MPEG-1 audio (VCD, SVCD, MP3)

Kalau kbps itu jumlah byte per detik [ukuran file].
Rumus untuk menghitungnya adalah jumlah sample suara [KHz di atas] * jumlah channel.
1 channel = mono = 8 bit = 1 byte.
2 channel = stereo = 16 bit = 2 byte.
dst.
