Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
The sound recording and storing method of the embodiment of the invention, behind extraneous input audio signal, convert digital signal to, and described digital signal and digital music signal in playing carried out mixing, the data that convert the audio compression form to output to memory device and store.
As shown in Figure 1, the sound recording and storing method of the embodiment of the invention may further comprise the steps:
In step S201, convert analog electrical signal to from the linear electric signal of external input or after the simulating signals such as singing sound of microphone input, and analog electrical signal is amplified/go hot-tempered processing.
Generally, more weak from the analog electrical signal that the external sound of importing is directly changed into, and noise is also bigger, therefore, needs small and weak analog electrical signal is amplified and go hot-tempered processing, improves tonequality.
In step S202, carry out the A/D conversion with amplifying/go hot-tempered processing analog electrical signal afterwards, convert analog electrical signal to digital signal.
In step S203, the digital music signal in digital signal and the broadcast is carried out outputing to external memory device after audio mixing, the compression processing, store.
Step S203 specifically comprises:
A:, obtain the digital music signal in the dvd playback through inspection sign indicating number, verification with the servo radiofrequency signal that obtains;
B: the digital signal that receives and digital music signal in playing are carried out mixing, make the voice data of recording at last comprise digital music signal in the dvd playback and people's singing sound.
C: the digital signal behind the audio mixing is carried out the audio coding compression handle, the data that convert the audio compression form to are stored.
Data volume was bigger after the voice signal of input converted digital signal to, if do not compress processing, than higher, the space that accounts for is also bigger to the requirement of hardware.
D: the data of the audio compression form of transmission are cushioned through buffer zone.
Described buffer zone comprises to be recorded the thread buffer zone and preserves the thread buffer zone.Before cushioning, judge whether to withdraw from and record;
If will withdraw from and record, output is recorded the data of thread buffer zone to memory device, stores;
If will proceed to record, receive and judge whether record the thread buffer zone full after the data of audio compression form of transmission, if record the thread buffer zone less than, proceed audio mixing and compression; If it is full to record the thread buffer zone, the function exchange with two buffer zones wakes the preservation thread up.The data that to just have been recorded by the preservation thread are saved in memory device.
Fig. 2 shows the structure of the audio-visual devices that the embodiment of the invention provides, and for convenience of explanation, only shows the part relevant with the embodiment of the invention.This audio-visual devices can be that video disc player, MP3 player or other can playing back music and the various audio-visual devices of video recording.
Convert analog electrical signal to after the simulating signals such as voice signal of audio frequency input block 201 reception inputs and be transferred to A/D converting unit 202, A/D converting unit 202 is transferred to encoding and decoding main control unit 203 after converting the analog electrical signal that receives to digital signal; Radiofrequency signal unit 204 is obtained by servo-drive system after the radiofrequency signal of the background music data in the dvd playback examining through the 205 pairs of radiofrequency signals in inspection code check unit and converts the music data in the dvd playback to digital music signal behind the code check and export to encoding and decoding main control unit 203; The digital music signal of the digital music signal of 203 pairs of A/D converting units of encoding and decoding main control unit 202 output and the 205 modules output of inspection code check unit synthesizes voice data and outputs to external memory device and store.The generation digital data transmission was given audio coding decoding module 2032 after the audio mixing module 2031 of encoding and decoding main control unit 203 was carried out hybrid processing with the digital signal of A/D converting unit 202 transmission with the background music sound signal of inspection code check unit 205 transmission, audio coding decoding module 2032 is compressed the digital signal behind the audio mixing, be transferred to buffer module 2033 after converting the data of audio compression form to, export to external memory device 30 after buffer cell 2033 cushions the data of transmission and store.
The buffer module 2033 of the embodiment of the invention comprises equal-sized two buffer zones, i.e. first buffer zone and second buffer zone.First buffer zone and second buffer zone all can be used as the input and the preservation of the voice data behind the coding.When beginning to record, all less than the data of storage, first buffer zone receives the audio mixing of audio coding decoding module 2032 transmission, the data after the compression as the input block of coded data at this moment for first buffer zone and second buffer zone; When first buffer zone is full, first buffer zone is as the preservation buffer zone of coded data, give the input block of external memory device 30, the second buffer zones with the audio data transmission of preserving, receive the audio mixing of audio coding decoding module 2032 transmission, the data after the compression as coded data; When second buffer zone was also expired, second buffer zone was as the preservation buffer zone of coded data, and first buffer zone becomes empty after giving memory device with the audio data transmission of preserving, and is converted to the input block of coded data.Described first buffer zone and second buffer zone are used alternatingly, the buffering of the voice data after realizing encoding.
The audio compression form of Cai Yonging can be AAC (abbreviation of Advanced Audio Coding), MP3 (MPEG Audio Laye-3), OGG (OGG Vobis), WMA audio compression forms such as (WindowsMedia Audio) in embodiments of the present invention, and the voice data synthetic at the encoding and decoding main control unit is forms such as AAC, MP3, OGG or WMA.
The external memory device 30 that connects in the embodiment of the invention is external memory devices such as storage card (CF, SD, SM, MMC, MS) or USB flash disk.Memory device 30 is connected with the encoding and decoding main control unit by the interface units such as USB/CARD interface unit of stereo set 20.
The sound recording and storing method of the embodiment of the invention, with the input voice signal convert digital signal to after, background music in digital signal and the broadcast is carried out carrying out storing after the encoding compression processing behind the audio mixing, the sound recording and storing method that external sound (Karaoke and linear input audio signal) can be recorded is provided, has solved the problem that people can't realize " sang and stay sound ".
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
