What is bit rate and why is it important?
With today’s technology, we can expect high speed and quality in everything we do on our computers, our smartphones, and any other newer devices. However, although this increase in speed and quality has several factors, many of them have to do with what is called the bit rate.
What bitrate means depends on the context you’re using it in, but it’s very important to know what it is and what benefits it might bring you (or what to expect instead).
What is the bit rate?
Bit rate is a term used to describe the amount of data that is transferred over a period of time. Depending on the context, common bitrate measures include kbps and Mbps, respectively, which means kilobits per second and megabits per second. Regardless of which drives are used, a higher number is usually good, indicating high speed or high quality.
However, it is also important to understand that smaller numbers can reduce the load on your hardware, which can be important for devices such as smartphones and netbooks.
When it comes to internet speed, a higher bit rate is always desirable – it doesn’t overload your own hardware, it just sends you the content you want faster. With higher bit rates, you can do more with an Internet connection – stream HD movies, play online games with minimal latency, and download large files in just seconds.
You can find out what bitrate you are getting by visiting a website like speedtest.net and running your tests. The numbers are good to compare with others, but generally don’t expect the expected number (other than the number your ISP announced). Certain parts of the world and Google Fiber users can get speeds of up to 1 Gbps (1000 Mbps), while typical cable broadband users in the US can get as low as 10 Mbps.
There has been a lot of discussion in online communities like Reddit about high internet prices in the US due to how slow speeds are, and initiatives like Google Fiber are starting to pay off.
When it comes to audio and video, bit rates take on a different definition. In this context, bit rates refer to the amount of data stored per second of multimedia playback. For example, a 320 kbps MP3 audio file has a higher quality than the same file at just 128 kbps, as long as both files were created from the same ideal source. You will have to remember that you cannot improve an audio file that sounds bad by copying it to an audio file with a higher bit rate, as the source was bad from the beginning. So a higher bit rate is a general rule of thumb, but it is not 100% correct.
The same is true for video: a higher bitrate will have a higher quality when comparing the same video with the same resolution. The bit rate is expected to increase as the resolution increases as more data is processed. Consequently, high bit rates for audio and video can provide superior quality, but can also put a lot of pressure on your hardware, which can lead to stuttering.
Also, keep in mind that different file formats use different compression algorithms, which can result in lower bit rates and higher quality. However, for these algorithms, the processing load tends to increase.
