Sample rate and bit rate<\/strong><\/p>\n

\"Sample<\/p>\n

If the file size is reduced (code at a lower bit rate), the sound quality tends to deteriorate. How much should it really be? .. ..<\/p>\n

\"sample<\/p>\n

When compressing using audio encoding (AAC, MP3, etc.), the compression rate is determined by the bit rate at the time of encoding. Specifically, if you set a low bitrate, the compression rate will be high and the file size when saved will be small, but what is the bitrate for the original sound source (PCM) without compression in the first place?<\/p>\n

If you save it as PCM, the sound quality of the original sound will be obtained, but it can be a little inconvenient to save it without worrying about the file size. Also, depending on the application, I think the original sound size has enough memory capacity and the communication speed is correct. Therefore, I would like to write about the sample rate and bit rate that are often heard in digital audio.<\/p>\n

The bit rate of digital audio is determined by the sampling frequency, the number of bits assigned to a sample (number of quantization bits), and the number of channels (stereo, monaural, etc.).<\/p>\n

PCM bit rate (uncompressed) = sample rate x number of quantization bits x number of channels
\nAs I wrote a bit last time, in file containers like wav and mp4 format, this information is attached as a header, so that the application can see the header and play it back. The compression rate of the encoding is determined by the bit rate specified at the time of encoding for this PCM (uncompressed) bit rate.
\nFor example, as many of you know about music CDs, with 44.1 kHz stereo, this is the next bit rate.<\/p>\n

Music CD bit rate: 44100Hz x 16bit x 2ch (stereo) = 1411.2kbps
\nWhen encoding this with MP3, AAC, etc., you will naturally need to specify a bitrate less than 1,411.2 kbps. For example, when encoding at 256 kbps, the compression rate is approximately 18% and the file size is 1\/5 or less when the original sound is 100%.<\/p>\n

Encode Music CDs at 256 kbps: 256 kbps \/ 1,411.2 kbps = approximately 18%
\nGenerally, the sample rates of audio devices actually connected to a PC are 48 kHz and 44.1 kHz for music, 16 kHz and 8 kHz for audio such as microphones and headphones, and 32 kHz, 24 kHz, 22.05 kHz. , etc.<\/p>\n

The bit rate of PCM (uncompressed sound source) with 16-bit quantization bits is as follows.<\/p>\n

Stereo (for music) PCM 16-bit bit rate (example)
\nSampling frequency Number of quantization bits Number of channels Bit rate Comments
\n48 kHz 16 2 1,536 kbps
\n44.1 kHz 16 2 1,411.2 kbps Music CD
\n32 kHz 16 2 1,024 kbps
\n24 kHz 16 2 768 kbps
\n22.05 kHz 16 2 705.6 kbps
\n16-bit monaural PCM bit rate (for audio) (example)
\nSampling frequency Number of quantization bits Number of channels Bit rate Comments
\n32 kHz 16 1 512 kbps Super Wide Band
\n24 kHz 16 1 384 kbps
\n16 kHz 16 1 256 kbps Broadband
\n8 kHz 16 1 128 kbps Narrowband<\/p>\n

Sampling rate<\/p>\n

If you check the web, there are explanations such as the sampling required to convert analog waveforms to digital conversion. For example, it shows how many samples of an audio signal input from a microphone are taken per second and digitized. The larger the sample, the greater the range that can be recorded. When an analog waveform is digitized, the frequency that can be expressed is half the sampling frequency (sampling theorem). For example, with a sampling frequency of 48 kHz, it can be expressed up to 24 kHz. At 8 kHz (narrow band) and 16 kHz (wide band), which are often used for audio, you can only hear up to 4 kHz and 8 kHz, respectively. The higher the sample rate, the higher the bit rate.<\/p>\n","protected":false},"excerpt":{"rendered":"
