Abstract
The invention discloses a sound recording gain regulating system with a sound recording effect monitoring function. The system comprises a sound signal acquisition module, a processing module, a gain control module, a synchronous monitoring module and a storage module, wherein the sound signal acquisition module, the gain control module, the synchronous monitoring module and the storage module are respectively connected with the processing module. In the sound recording gain regulating system and method with the sound recording effect monitoring function, a sound recording synchronous monitoring unit and a gain regulating unit are added in a sound recording system, so that users can monitor the sound recording effect while recording sounds, and simultaneously, the users also can synchronously regulate the sound recording gain according to the sound recording effect, thereby improving the sound recording effect.
Description
Technical field
The present invention relates to a kind of recording system, relate in particular to a kind of can the monitoring recording effect and regulate the system and method for recording gain.
Background technology
Along with the fast development of portable electric appts, the performance of portable electric appts is more and more higher, and function also from strength to strength.Now, sound-recording function has become indispensable in a portable electric appts function.Common recording system generally includes only the sound signal collecting device, microprocessor and storage device.In whole Recording Process, the user can not the perception recording effect, can not regulate recording effect.Because the polytropy and the complexity of playback environ-ment, recording effect is subjected to Effect of Environmental very big, and the user wants to hear that recording effect can only be waited until just can hear its recording effect by the playback document after the End of Tape.At this moment, getting well with evil idea of recording effect is not subjected to user's control.
Summary of the invention
In order to solve existing technical problem in the background technology, the present invention proposes a kind of system and method that has the recording effect monitor function and regulate the recording gain, in recording system, add synchronous monitoring unit of recording and gain adjustment unit, the user can pass through the synchronous monitoring recording effect of earphone in Recording Process, can gain according to the recording of recording effect adjusted in concert simultaneously, and then improve recording effect.
Technical solution of the present invention is: the system that has the recording effect monitor function and regulate the recording gain, and its special character is: described system comprises sound signal collecting module, processing module, gain control module, monitors module and memory module synchronously; Described sound signal collecting module, gain control module, monitor module and memory module synchronously and be connected with processing module respectively.
Above-mentioned gain control module is manual MIC gain control module or automatic MIC gain control module.
Above-mentioned synchronous monitoring module is connected with earphone or loudspeaker.
The method that has the recording effect monitor function and regulate the recording gain, its special character is: said method comprising the steps of:
1) carries out sound signal collecting, voice signal is converted to the sound signal of telecommunication;
2) the sound signal of telecommunication is handled, transmitted and preserves;
3) by gain control function the sound signal of telecommunication is recorded, and gain-adjusted;
5) recording is preserved.
Above-mentioned steps 3) comprises also that afterwards step 4) in Recording Process, monitors by synchronous monitor function.
Above-mentioned steps 4) monitor function transmits by earphone or loudspeaker in.
Above-mentioned steps 4) specific implementation is: if the sound of hearing from earphone or loudspeaker is less, will gaining, it is big to transfer; If sound is bigger, gain is turned down.
The system and method that has the recording effect monitor function and regulate the recording gain of the present invention, in recording system, add synchronous monitoring unit of recording and gain adjustment unit, the user can pass through the synchronous monitoring recording effect of earphone in Recording Process, can gain according to the recording of recording effect adjusted in concert simultaneously, and then improve recording effect; The user can regulate the size of recording gain freely according to the demand of self fully, has more flexibility in the control to recording effect.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the specific embodiment of the present invention schematic diagram;
Embodiment
Referring to Fig. 1, Fig. 2, the system that has the recording effect monitor function and regulate the recording gain of the present invention comprises sound signal collecting module 1, processing module 2, gain control module 3, monitors module 4 and memory module 5 synchronously; Sound signal collecting module 1, gain control module 3, monitor module 4 and memory module 5 synchronously and be connected with processing module 2 respectively, sound signal collecting module 1 converts voice signal to the signal of telecommunication, 2 pairs of voice signals of processing module are handled, and transmit and preserve; Gain control module 3 is regulated the recording gain; Monitoring module 4 synchronously records by earphone or loudspeaker synchronous playing in Recording Process; Memory module 5 is preserved audio archive.The course of work is: processing module 2 will be handled from the voice signal that sound signal collecting module 1 collects and store memory module 5 then into, meanwhile monitor module 4 synchronously the voice signal synchronous playing is arrived earphone.The user can according to from headphone monitor to result of broadcast, the size of regulating the recording gain by gain control module 3 if the sound that the user hears from earphone is less, then will gain and transfer greatly; Otherwise, then gain is turned down, up to reaching best recording effect.
The specific implementation method, referring to Fig. 2, system prompt user whether will plug in the earphone (because might just on the classroom), open the Bypass function of CODEC, this moment, the user can record on one side, on one side the monitoring recording effect, and the user can be according to monitoring effect manual adjustments recording gain up to reaching best recording effect, preserve gain after adjusting is finished, close the Bypass function and begin actual recording.And just can finish the gain-adjusted of once recording in a short period of time.Can make each recording can both reach best effect according to the size apart from free adjustment recording gain of source of sound and electronic dictionary by the native system user.For example the distance of each student from the dais is not wait, as long as the recording that is provided with of suiting measures to local conditions gains.
The method that has the recording effect monitor function and regulate the recording gain, this method may further comprise the steps:
1) carries out sound signal collecting, voice signal is converted to the sound signal of telecommunication;
2) the sound signal of telecommunication is handled, transmitted and preserves;
3) by gain control function the sound signal of telecommunication is recorded, and gain-adjusted;
4) in Recording Process, monitor by synchronous monitor function; Monitor function transmits by earphone or loudspeaker; If less from the sound that earphone or loudspeaker are heard, will gaining, it is big to transfer; If sound is bigger, gain is turned down;
5) recording is preserved.
