Embodiment 1

[0026] Such as figure 1 Shown is a functional block diagram of a sound recording method of the present invention. What apply a kind of sound recording method of the present invention is an MP3 player 20, and this MP3 player 20 comprises an MP3 processing unit 1, a linear input port 2, a microphone 3, a storage unit 4, an expansion storage unit 5, a A display unit 6 , an operation input unit 7 , a USB communication port 8 , an earphone and a line output jack 9 . Signal connection between MP3 processing unit 1 and storage unit 4, expansion storage unit 5, display unit 6, and operation input unit 7; linear input port 2 is connected to analog-to-digital conversion module 120 in MP3 processing unit 1; microphone 3 is connected to MP3 processing The preamplifier 10 in the unit 1 ; the headphone and line output jack 9 is connected to the headphone drive and line output unit 220 in the MP3 processing unit 1 .

[0027] MP3 processing unit 1 is used to run the entire control program o...

Embodiment 2

[0037] Such as Figure 4 As shown, it is a functional block diagram of a sound recording method of the present invention in another embodiment. The preamplifier 10 can also be placed outside the MP3 processing unit 1 . The rest of the circuit structure and principles are the same as those in Embodiment 1. When the preamplifier 10 is placed outside the MP3 processing unit 1, the purpose of switching the input can be achieved through the switch in the linear input port 2, and its specific working method is as follows: Figure 5 shown. Figure 5 It is a schematic diagram of the changeover switch in the linear input port 2 of Embodiment 2 of the present invention. When the wireless input plug (not shown) is inserted, the A, B contacts and the C, D contacts are all in a conducting state, and live music and other external sound information pass through the microphone 3, the preamplifier 10, and then through the A, B, and D contacts. The B contact and the C and D contacts enter t...

Abstract

A method for recording sound includes obtaining on ¿C site music or other external sound from microphone and converting it to be electric signal, amplifying obtained sound to generate digital audio signal, generating audio file according to digital audio signal and storing audio file. In the method microphone is applied to record on ¿C site music or other external sound for ensuring quality of music instrument playing back sound.

Description

【Technical field】 [0001] The invention relates to a sound recording method and device, in particular to a sound recording method and device for recording live music and other external sounds using an MP3 player. 【Background technique】 [0002] With the development of modern information technology, some emerging technologies and new things related to the network are coming into our lives. In recent years, along with the spread of computer networks, music in MP3 (Moving Picture Experts Groupl Layer-3) data format has rapidly become popular in the network world, and MP3 players (players) are gradually becoming familiar to consumers. With the development of technology and the demand of the market, MP3 has developed from only playing MP3 music at the beginning to being able to play digital music in multiple formats at the same time, and has developed from a simple audio playback tool to an individual that integrates entertainment, learning and life. Digital music products. Exis...
