For the digital recording pen, the first concern is the recording time, and the length of the recording time is the most intuitive indicator of the digital recording pen. The length of the recording time is related to the storage specifications of the sound file supported by the recording pen. Currently, there are three basic modes of LP (long-time recording), SP (standard recording), and HQ (high-quality recording). In addition to these three modes, there is a SHQ (Ultra High Definition Recording) mode, but there are few digital recording pens with this mode. The standard recording time refers to the maximum recording time supported by the recording pen memory in SP mode.
Taking a one-hour recording as an example, the LP format file occupies 1.94 MB of memory, and the SP format file occupies 3.89 MB of memory. The HQ format file occupies relatively large memory. For example, a 32MB memory recording pen can record up to 1140 minutes in LP format and only 710 minutes in SP format. If it is in HQ format, it can be down to 140 minutes.
The length of the recording time is the most important technical indicator of the digital recording pen. It is also one of the places where the majority of consumers pay the most attention when buying. There are many brands of digital recording pens on the market, and there are many product models. Because this indicator is related to the flash memory capacity and the compression algorithm of the recorder, the recording time varies greatly. Therefore, the length of the recording time becomes the chief purchase time. Considerations. Some products record for a long time because they use a high compression rate to compress the recording data, and this compression sometimes reduces the quality of the recording. Therefore, we cannot blindly pursue long recording time when choosing, but we should consider the recording time and recording quality in a balanced manner. The single recording time is long, but the recording quality is not good. The standard recording time of digital recording pens is currently 6-10 hours, which can meet the needs of most people.

LP recording mode LP (LongPlay) is a long-time recording, high compression rate, through the sacrifice of a certain sound quality to extend the length of the recording, you can generally increase the length of recording time by about 80%. That is, at the cost of reducing audio quality, there will be a certain reduction in sound quality.
SP recording mode (Standard play) is the standard recording time. In this mode, the compression rate is not high, the sound quality is relatively good, and the recording time is moderate.
HQ recording mode HQ (High quilty) high quality recording. This recording method has a very low compression rate, sound quality is very good, but the capacity is relatively large, generally suitable for demanding occasions, such as archival records for important speech
