MP3 is of much use.
One, the different MP3, contains the function many dissimilar. With the advancement of Science and technology, these functions mainly include:
1. Removable hard disk: The computer directly recognizes the MP3 as a removable memory, MP3 which can store all kinds of documents except music.
2. Firmware Upgrade: To resolve the release of the product after the knowledge of software, hardware failures, add new features.
3. Folder browsing: Storage of different songs by folder, and play in this unit, not all MP3 are placed under the same directory, improve ease of management.
4. Multi-national languages: mainly support Chinese Simplified, Chinese Traditional, Korean, Japanese, English, some models even have 26 languages.
5.-Repetition: Read a paragraph of content repeatedly, easy to learn a foreign language.
6. Text reading: Usually only the screen big MP3 have this function, can when the e-book look, some products also support the PDA text format. If the firmware capacity is sufficient, MP3 you can also download various Chinese and foreign text bodies.

Can even read while listening to MP3, as the function of a simplified PDA.
7. TTS (text-to-speech, text speech aloud), the text directly with MP3 audible conversion to text, the machine sound and rhythm change, it sounds strange, MP3 but very suitable for the lazy people do not want to read.
8. Dictionary: English-Chinese dictionary, used as translation, MP3 note that MP3 control keys are limited, and it is not easy to enter English words.
9. Automatic recording function: Through SAD (Sound activity detector, the sound activates the scout), may set the silent time length, only when has the sound only then will the recording, MP3 saves the memory space, saves the time in the playback time.
10. Remote recording: Using AGC (Auto Gain control, automatic gain controller), adjustable sensitivity and recording quality (low, heavy, high), MP3 suitable for long-distance external recording, such as: meeting.
FM: Listen to the radio, many products can preset a number of channels, no need to adjust each.
FM recording: The radio content is transferred to MP3, some products and FM recording! You can enter the day of the week, and how many Hertz channels to start recording, MP3 this is not a favorite radio program or foreign language learning programs will not be missed because of the busy, can be recorded slowly listening.
The EQ setting: the setting for sound effects. Almost every product will have several preset sound settings, such as ordinary, rock, jazz, pop, classical. Some MP3 also support custom sound settings that users can customize according to their preferences. But without the LCD display of the products, these EQ settings are almost non-existent, only one of its own curing sound mode. This is a bit of a cruel way for some friends who are particularly loyal to the effects of personal music.
14. Direct record: The external sound source (cd/md Walkman, home Audio, computer) coding compressed into music files, directly exist on the MP3. Because the MP3 machine built-in coding chip performance is poor, MP3 the sound quality is inferior to the computer compressed music file.
15. Clock: The time setting can enter the month day, cent, and can be used as a watch.
16. Alarm Clock: Can set the timer alarm clock, not only can beep in the ear, the microphone will also beep, without earplugs when the alarm will also take effect.

Because the screen of MP3 is small, the resolution is relatively high to see the picture will feel a beautiful, but most of the screen has a proportional limit, MP3 the proportion of the wrong will appear deformation and not normal display phenomenon.
19 Digital Camera: As in the early days of the mobile phone camera, using 10.3 million pixel $number. 5 "CMOS lens, the main disadvantage of CMOS is the brightness induction slow, so in the light of the environment to shoot the effect is better. The biggest advantage of CMOS is the small size, the most suitable for MP3 Walkman. The camera itself has a variety of functions, can be digital zoom, a variety of effects shooting.
Second, MP3 is a player that can play music files.
