The so-called device of the present invention, can be that hardware unit can also be module.
The so-called high-fidelity (High fidelity or Hi-Fi) of the present invention is the technical term that Fancier is used,
The energy perfect reproduction original work sound of finger or the equipment and carrier of image, usually not distortion, there is an accurate response frequency, this
Individual noun is widely used in 1950s to the sixties, and standard can have been worked out in 1973 by DIN chemistry.
Hi-Fi is English High-Fidelity abbreviation, is literal translated as " high-fidelity ", and its definition is:With original sound height
Similar playback sound.
Evaluate a sound system or whether equipment meets high-fidelity requirement, should typically be surveyed using evaluation of subjective acoustic level and objective indicator
The mode that is combined is tried to carry out, and using objective examination's index as Main Basiss.Because using the performance indications of instrument test equipment,
The quantitative result that can intuitively compare for reference can be obtained very much, it is undoubtedly most scientific and trustworthy.
During sound evaluation, overall merit should be carried out to the tonequality of equipment according to general term of evaluating.But evaluation of subjective acoustic level mode
Unavoidable band point is subjective random, is sometimes prone to audition attainment, audition psychology, custom, hobby and audition ring by the personnel of participating in evaluation and electing
The influence of the factor such as border and mode and draw controversial result.At this moment then should be using objective examination's result as main Appreciation gist.
The professional person of sound equipment circle is by means of each quasi-instrument, by various means, detects various indexs to determine equipment Hi-Fi
Degree, and Fancier then goes to judge whether equipment reaches in the eyes of Hi-Fi often through the ear of oneself.Differentiate weight
The height of sound reproduction pitch fidelity, not only needs the equipment and software of function admirable, but also to have good acoustic surrounding.
Therefore, the Hi-Fi degree of sound appliances how is correctly weighed, the difference of objective examination and subjective assessment is also there is, but had
Any can be certainly, that is, loyalty reduction, truly reproduces most pure music emotion.
Beneficial effects of the present invention can be summarized as follows:
1st, sample rate conversion equipment is that two input blocks are shaken with twin crystal does sample rate conversion respectively, one piece of correspondence 44.1k with
And integral multiple, one piece of correspondence 48k and its integral multiple, input different audios and use different crystal oscillators;Or two input blocks point
Sample rate conversion is not done using opa1618 or cs8422 chips, you can realize the high-fidelity sample rate of different sample rate audio inputs
Conversion.
2nd, dual input decoding apparatus can realize that dual input high-fidelity is decoded using the decoding of ES9018K2M chips respectively.
3rd, dual input is mixed puts device, and dual input high-fidelity is mixed, which to put use of the device in this link, realizes dual input high-fidelity
Audio mixing is exported.
4th, dual-audio player method of the invention can individually play accompaniment background audio-frequency or chant audio file simultaneously, and accompaniment is broadcast
Place system and to chant play system be non-interfering, realizes in broadcasting simultaneously, whole method after can also being put through overmulling and is separately controlled,
Separately play, or open playing device simultaneously simultaneously.With the player that the device of this method is MP3 or MP4 forms, also may be used
It is used in the mobile terminals such as flat board, smart mobile phone.
5th, player method of the invention has a variety of play mode:Individually play mode and broadcasting immediately plus alarm clock setting immediately
Period play mode.Played such as double track combination after content is selected and play automatic shutdown after n times immediately;Or double track combination is played
Automatic stand-by sleep state after n times is played immediately after content is selected, and the period set to the time by alarm clock continuously plays
Automatic shutdown after n times.In addition, the playing device of the present invention also has sound-recording function, audio or audio accompaniment are either chanted in deposit
Oneself it can be recorded according to occasion and mental state.The volume of two tracks can adjust setting and numerical monitor respectively, use
When volume of music be less than read aloud volume, meet different people volume custom;After two track combination broadcasting contents are selected, it can set
The re-reading number of times of double track, such as 3 times.
6th, the present invention is Promethean, is amplified the L channel for inputting audio respectively with an one-level amplifying device, with one one
Level amplifying device amplifies the R channel for inputting audio respectively, and each sound channel is to amplify respectively, adds the amplification member of high-quality
Part, reduces amplifier element number, and causes circuit to accomplish optimization design, so as to realize that mixer has the volume of mobile phone size.
7th, in the present invention, all amplifying devices are to amplify respectively to inputting sound channel signal therein, reasonable selection amplification member
Part, excludes the interference amplified jointly.Signal to noise ratio can reach 100dB, and total harmonic distortion reaches one thousandth.Signal to noise ratio, mistake
