The invention of the recorder has brought a lot of convenience to people. It can record the bits and pieces of our lives. It can also record some audio data. The length of time that the recorder can be recorded is usually a concern of people, and it is also an indicator to measure the cost performance of the recorder. So, how to accurately test the duration and make effective use of the recording duration? Here, I gave you a detailed explanation!
How long the recorder can record depends on the duration of the recording. The duration of the recording includes “the recording duration of the memory†and “the recording duration of the batteryâ€.
1, the recording time of the memory: As the name implies, the memory capacity can store how many recording files, that is, how long the recording content can be stored. Usually the larger the memory, the more recording time is stored. The recording pens on the market are generally 4G and 8G, and the price of these two memories is not much different. It is a few dollars, so I suggest you choose the 8G memory recorder. Now there are also recorders with expansion cards on the market. If there is no difference in price between the card and the recorder without the card, of course, the machine with the card is selected! This can satisfy your large capacity and multiple files. Storage needs!
2. The recording time of the battery. That is, how long it can be recorded after a full charge. This issue is the most interesting. In this case, we need to pay special attention to two aspects: First, the problem of the machine itself. This involves batteries and boards. When we choose, we must ask how long the machine is playing continuously. So we have to test it, use the most stupid method, charge the machine, put it somewhere, do not care about it, open the recording directly. Mode recording until the battery is exhausted. Generally, the recorder can be saved by power off, so don't worry. This way you can see the recording time of the machine. The second is the choice of recording mode. Basically, the recorders contain a variety of modes for consumers to choose from! The simpler recorders are divided into high-quality recordings and low-quality recordings; the more powerful recording pens are: 32kbps, 64kbps, 128kbps, 192kbps and 384kbps five modes. (kbps is the bit rate. The higher the bit rate, the higher the recording quality and the shorter the recording duration). So this requires you to choose according to the specific situation. (Note: It is usually said that the recording pen can record continuously for a long time, which is the result at the lowest bit rate). The third is to pay attention to special circumstances. Such as voice recording. Voice-activated recording means that if there is a sound, it will be recorded. If there is no sound, it will not be recorded. Therefore, if you turn on the voice-activated recording mode, the recorder will automatically save power when there is no sound source, and it will not work during this time. So the voice-activated recording mode can of course record longer!
The above is the recording principle of the recording pen. The recording recorder can record for a long time mainly to see the configuration of the recording pen. I hope the above introduction can help when you purchase the recording pen.
