Sticking to our theorem, this would mean a sampling rate of 40kHz. When it comes to digital video formats, the most common sampling rate is 48kHz and as a rule, sticking to this should always give you high-quality results.
In most cases, there is no audible difference. With the nature of capturing audio for video, it is unlikely that you will be getting very close in on high-frequency sound sources. However, on the occasions that you are then there is one very good reason for sticking with 48kHz.
As we previously mentioned, our sample rate is double the frequency range we wish to capture. This also means that any frequencies above half our sample rate will be captured as reflected frequencies. For example, at a 40kHz sample rate capable of capturing up to 20kHz , a signal with a frequency of 21kHz would be processed and perceived as 19kHz. Why is this bad? High-frequency distortion. If we end up capturing lots of high-frequency harmonics that are folded back into our top end, we can end up with distorting high frequencies.
Not something that sounds too pleasant. As an audio engineer, I often find myself running out of hard drive space. For you videographers, I can only imagine how many huge files you must deal with. Dedicating hard drive space and processing power to your video files is going to be chief. In order to keep it that way, making the correct choice with sample rates is key. Doubling that sample rate up to 96kHz is going to result in a file size of Now that you know how to decide on a sample rate for your project, stick with it.
The reason behind this is simple. An audio file with a sample rate of Remember Me? The No. Today's Posts competitions support us FAQ advertise our advertisers newsletter. When you buy products through links across our site, we may earn an affiliate commission.

I have always recorded in Video is 48Khz - should I therefore bounce one version at AFAIK, the only time that absolutely matters For example, YouTube will accept samplerates of You just need to embed it with a picture or video. I've always wondered which is the optimal format, bitrate, samplerate, loudness, etc, to submit to the various regular streaming services, so that their automatic transcoding processes will do the least damage, and sound the best they can.
The common thought is that most humans are able to hear between 12kHz and 20kHz. According to something called the Nyquist Limit, the sample rate should always be at least twice that of the highest frequency being recorded.
Once we sample below that limit, not only can we not accurately sample the signal, but the data we get out has corrupting artifacts. This explains why CDs are at 22 Hz frequency and have a sample rate of It is this basic principle that explains why The next question that naturally arises is why not record in a higher sample rate?
Logical thinking would dictate that increasing the sample size would naturally increase the quality. Hard drives are cheaper and bigger than ever so file size is less and less of an issue. However, the reality is not as simple as that might lead you to believe. First, increasing the sample rate increases the file size. Second, using a super high sample rate can lead to more errors, especially with digital signals being sent to analog sources.
Theoretically, using a super high sample rate such as 96kHz will be a waste for a majority of listeners.
