What is the sampling rate? Part 2
Sampling rate (Hz) x bit depth (bit) = bit rate (bps)
Will be.
for example,
Sampling rate: 44100Hz
Bit depth: 16 bits
stereo
for music files
44100 (Hz) ✕ 16 (bit) ✕ 2 (stereo) = 1411200 (bps) ≒ 1411 (kbps)
Will be.
Uncompressed wav bitrate is about 1400kbps so it fits.
Since the audio bitrate of Youtube video is “192kbps” at most, you can see that the amount of information is almost 7 times different from uncompressed wav.
Reference : Upload/download high quality video to Youtube = impossible
By the way, “bps” can be converted to “B/s” by dividing by “8”.
So it can be “1411/8 = 176 KB/s”.
It means that the uncompressed wav contains 176 KB of data per second. (88,000 double-byte characters)
In other words, “increasing the bitrate” means
Increase the “sample rate” or “bit depth”
That’s what it points to.
resume
・ Sampling rate: “How many tens of thousands of sounds are collected per second?”
-Bit Depth: “How much capacity is given to each split data”
-Bit rate: Multiplying “sampling rate” and “bit depth”
