Embodiment 1
[0039]WAV format, also called waveform sound file, is the earliest digital audio format and is widely supported by the Windows platform and its applications. The WAV format supports many compression algorithms, supports a variety of audio bits, sampling frequencies and channels, adopts a sampling frequency of 44.1kHz, and 16 quantization bits, so the sound quality of WAV is almost the same as that of CD. However, the WAV format requires too much storage space and is not convenient for communication and dissemination. When users use external mobile storage devices with small capacity, such as USB storage devices, MP3 players, etc., they hope to convert music in WAV format into music with higher sound quality. It is best to use a data format with a high compression rate, such as WMA format and MP3 format.
[0040] Use the Auto Run function to automatically start the music data transcription program.

[0057] Many digital products support the user's personalized needs, such as mobile phones can customize the prompt tone of incoming calls and short messages, and digital cameras can also customize the tone of power on and off and certain specific operations. Most mobile phones can now customize the prompt tone for incoming calls and short messages. The short message prompt tone lasts for a short time, which is suitable for turning on and off the digital camera.
[0058] Depending on the mobile phone, the data format of the prompt sound is different, and the digital camera supports a variety of prompt sound formats. Therefore, when the user wishes to store a certain prompt sound from the mobile phone into the digital camera as the prompt sound of the digital camera, There will be a format mismatch, requiring format conversion.
[0059] Set a startup data area on the memory card of the digital camera, which is used to store the autorun file Autorun. Ordinary pictures and other ...

[0084] Compared with other music formats, WAV format is superior in sound quality. Many users who have high requirements for sound quality hope to convert CD music data to WAV format and save them in computers or external storage devices, so as to ensure high sound quality.
[0085] The external mobile storage device in this embodiment is a Flash card reader with a USB interface. When the Flash card is inserted, the data stored in the Flash card can be read and automatically exchange data with the operating system according to different Flash cards. This embodiment triggers the computer to automatically start the music data transcription program through the auto-run function, converts the music data in the MD into WAV format, and stores them in the Flash card.
[0086] The Flash card includes a boot data area and a storage data area. The startup data area stores the auto-run file Autorun.ini and the programs specified in the auto-run file Autorun.ini, etc., and can also store...
