1887 Edison invented the human history of the first recording devices-phonograph.

Information of the record of the text, since the recording devices to record-voice.

Audio-the use of recording devices (including equipment) and recording media on a recorded sound signal.

Recording engineer-use of recording devices and equipment for voice recording. Means of radio, television, film, video, advertising, network, and other audio recordings.

Characteristics of contemporary recording

1, new technologies, high-tech applications: 1887 Edison's phonograph and subsequent recordings are machinery records, its sound quality is poor. 1904 United Kingdom by J.A. Fleming invented the second pole tube; 1906 United States person L DeForest invented electronic transistor. It is made using electronic transistor amplifiers, sound amplification of thousands of times. In 1924 after electromagnetic marking head and microphone have invented, recording technology is mature.
Today, the recording technique widely used in news broadcasts, culture, entertainment, advertising, information and other fields. Electronics technology, computer technology, laser technology, information technology, the latest results. Representative embodied in digital multitrack recorders, laser record player, a digital mixer, audio workstations, etc.

2, the fusion of technology and art: recording work is neither a purely technical exercise, nor is it a purely artistic work. Recording work reflects a comprehensive technology and art. We use technical means to create art, you must follow the technical norms and rules of the art of writing, recording engineer must have a variety of quality, such as: acoustic, music, recording devices, computers, etc.

3. recording instruments and artistic creation: recording of Foundation is to understand the sound source, the source of many types, such as: voice, natural sound of acoustic, mechanical, and acoustic instruments. The characteristics of the sound source. Pickup is how to select and display the receiver, according to the requirements set microphone parameters, the sound signal transducer (microphone) into electrical signals. Tuning is the audio signal effect of the treatment, mixing and allocation process. The recording is to signal sound signal is converted to a magnetic signal or optical signals recorded in the appropriate medium. Also the sound is recorded in the media on the signal back to sound process.

All aspects of the use of the equipment is different, so be on the recording device in familiar, as the saying goes, "practice makes perfect".

Recording and recording career

People's Republic of China was founded in 1949, Chairman Mao a solemn proclamation of the "Tiananmen People's Republic of China was established, the Chinese people have stood up" recording to record this moment in history.

Our professional ceremony will include radio and television recording career in the industry.

With the development of the society, recording career has been updated to explain, is he not the broadcast television industry patents and is the information society in a wide range of applications in various industries.

2001 China recording engineers and Technology Department Zhao Ping-kun began to organize writing recording national occupational standards, 2002 formally included in the establishment plan in February of that year was the discussion of the draft in April 2003, 20, national Ministry of labour and social security, employment training, identification guidance Center standard textbook Department Organization experts on the recording of occupational standards were finalized, after careful examination of experts and to modify the standard formal adoption can try out.

2003 Beijing Kun-vocational training school is first batch recording engineer trained scored People's Republic of China Ministry of labour and social security issued by a recording career qualification certificate.

Recording level is divided into five levels: Assistant recording (5 levels), recording engineer (fourth level), intermediate audio Division (level 3), recording technician (L2), advanced audio Division (level).

Music recordings
Radio and television stations, the vast majority of music and art in 200 square meters in the recording Studio. After years of continuous practice and research, summarized some experience, and recorded a number of high quality music program.

The music is pure sound with an organized to create artistic images, expression of feelings, reflecting the art form of social life. It to melody, rhythm, tempo, mood, tonality, harmony, counterpoint, speed, strength, tone, and so on as essential method, is good at direct expression of feelings, have a special artistic appeal. Generally speaking, in 200 m 2 Studio to record a music program includes instrumental music playing, singing and small Orchestra, etc. The recording process, the main problems to be solved is how to record a live sense, the sense of a distinct, hierarchical environment clearly music program.

First, the formulation record programmes were recorded good music. We know that big to one party, as small as a song, there are many departments and positions of the personnel Division. For singing, for example, to the Studio to record a song and dance ensemble of the majority of professional actors and a number of media organizations in the singing contest winners, some knowledge of music theory, comparative understanding of the stage feels good; some of the Studio as a karaoke stage. At this point, the recording of duty is to assist the Director (if you have a Director) to develop a complete recording solution. On this point, there is no system, perfect art concept, there is no outstanding sound and artistic works, just like a restless River streams, mainstream music is there.

Recording songs, singing, sound effects, music, three factors to be balanced, carry out their duties, the Division of labour. Each part of the texture, direction, distance, size, level, speed, etc. are to follow the music in order to achieve a sound glances, immersive artistic effects. We recorded a song for the first chorus, record must be balanced so that all voices, balanced and avoid side to side light; the allocation of the volume that you want to highlight the major and minor, so that the main outs and accompaniment structured; therefore, the leader in chorus and must be between songsTheme, master and timbre, in sound and image design reflects the liveliness and the layout of contrasts.

During recording, inevitably encounter recording and commanding, actors and coordination problems between the communication. We are currently recording music festival, generally and creative professionals, directors (or edit) a careful analysis of the topic idea and works to develop common research programmes, recording how the successful completion of the recording.

Secondly, because of different historical backgrounds, geography, language, in the case of system, customs and other reasons, different kinds of music has its long-term form of artistic features and unique charm. To record a good music, have an in-depth understanding of the work topics, styles and singing, and singing of features to be addressed

There are many studio recording equipment using a combination of analog and digital recording system, usually a digital audio workstation, in music of timbre and pitch for some special treatment. By using effects and adjust the EQ Equalizer sound mixer to make sound mellow energetic; application of Spectral audio workstation into 8 out of 8 (A/D converter with 8-track, 8 rail out) function, various voices take separate track recording. When recording a chorus, sometimes instrument appears the phrase double chorus on bit is not very neat, listen, there is a sense of chaos, at this point, you can use SHIFT and the workstation, copy function for verbatim on bit reduced rail and rail-replication, then appropriately adjust the track's volume and mutual priorities in this way, a few dozen people's Chorus had 100 people's chorus of the might momentum and uniform, the effect is outstanding.

For example, in the creation of the "song of gulangyu Island, we will together with the composer, conductor, research and discusses how the orchestration of the music score for recording. The prelude to the songs, the need for a short time, thanks to the soothing sound of the waves in a hurry, we found from CD a rattling sound of the waves, but the results were not satisfactory (more like a music with MIDI synthesis). Our ideal gulangyu wave is both a mountain, and full of tenderness, and finally we decided to make your own. First recording a suitable wind, then uses the workstation shearing a CD iisten, use workstation reverberation, balanced, audiovisual panorama, compressor, noise reduction, mixing a we believe iisten quite satisfactory. As a prelude to the effects of the weak crescendo of waves, final smash, spray, splash in the ocean breathe rooms reflect the fascinating beauty of Gulang Island, so we had to do on the workstation of the waves crashing on the pitch, the graphic is enlarged, then cut off after all the silent before, use the workstation's copy, paste functionality out of a series of continuous superposition of waves crashing on the tone, then applying effects and workstation track volume adjustment and memory functions, recording a more lifelike sound of the waves.

Due to the shorter (only ten seconds or so), the general feeling of the cut out iisten no rendering cycles of time and space, especially in the end of a dull and boring. In order to reflect the waves from very very dynamic to static, we from the original CD of iisten find a connotation and mood are more appropriate in the trilogy, pinch head and tail, and then apply the head and tail were made fade handle, remove the abrupt break marks, and then add that code to move to another track, immediately after the original sound of the waves, and by adding the appropriate reverb sound mixer, immediately feel and true Vocality seamless glimpse into Golden Beach, listening to the journey of a long run surge. In the song of gulangyu island at the end of the performance needed for a period of high tide, the sea before you need to show some happy loving mood. At this point, the transformation is an effective means of music features, we passed control mixer volume, with the pitch from weak crescendo, gradually into songs in high spirits, warm praise passage of rhythmic fluctuations make songs have refreshed the dripping of climax.

In order to demonstrate the love of the motherland in the song, longing for the youth and the natural combination of artistic effect, we focus on mastering the music sound and sound (contrast with the polyphony of the chorus, contrast) results; the creation of the song, not in the process; yea, in the natural real music status reflected in the high level of artistic pursuit.

In the post-production stage, we also use audio station "SOLO" function, the recording of each part individually, to sing in a low pitch has taken a digital upgrade. After a carefully organized and produced so that the whole song in every part of the match after about location is just right, time, space and depth organic distribution to each sound source.

Through two weeks of meticulous recording, making the song reached the high artistic level, the evaluation has also attained good results.

In the studio recording music programmes, not only to grasp the recording technology and, more importantly, on the theme of musical events, artistic characteristics for in-depth analysis and understanding of, and co-ordinating the recording to sound glances to acoustic phenomenon.

Music recording system of control techniques

1. delay and reverb

We all know, reverberation processing is more complex delay feedback, and such effects processing is the most complex and changeable. As a professional music recording system, it is recommended that you configure here should be at least four sets of reverberation.

At present the most versatile effect treatment plant are all digital, the effect of species can be said to be very rich, but a separate one effects processing voice, rarely achieve satisfactory results.

Voice of reverberation processing, the ideal configuration is to use 3 effects. One digital reverberator. One digital reverberator for forming the main reverberation; a mechanical reverberator, used for the original signal and reset the dyeing effect; a digital delay unit, used in the production of ECHO. If possible, you can also configure the following use of effects processor:

(1) basic retouching reverb effect, for the simple integration of additional sound source and the degree, but do not produce residual ring tail. Here you should use early reflection echoes or door reverb effect.

(2) drag the reverb processing, used to increase the main theme and the accompaniment of the blend of a strong, free dyeing of reverberation processing, such as the Hall reverb among them, steel plate, spring reverb mode, the reverberation time is placed 3 ~ 10 seconds, the longer the delay should be set, such as in between 100 ~ 800ms. Comparison of foot less reverb to their pronunciation can hide among the accompaniment of voices.

In fact the main melody is to add a low loudness and high integration of acoustic background, this acoustic background blend to accompaniment part, as is the accompaniment of harmony, melody, however it also has a strong affinity, this theme is very good and accompaniment harmony together.

(3) the chorus effect processing. This can be of two sound sources made seven or eight or a large crowd chorus effect, very suitable for singing, harmony and Chorus effects.

The best is to use three or four sets of effects is parallel, and the chorus effect should set different parameters. As the chorus processing with still FM treatment, it is recommended that you do not use in-line mode to avoid excessive pitch piaodong.

Chorus itself experiments in medium and high frequency bands with confusion, opacity effect, choral processing if you are too heavy, even at this point as the chorus, and reset the reverberation processing will easily cause turbidity in which frequency, high-frequency sometimes produces scream sounds, and recommending appropriate high frequency attenuation choral channel. Note that some digital effects are relatively dark boring "swarm" effect, does not prevent a try.

The above three treatments may cause the audio system's effectiveness is configured to 1989. This for most audio bin, obviously not easy to achieve on the economy. Good for General digital effects on both the processing mode of the preset program, you can increase the effects that these preset programs, and will deal with the effects of the recorded signal track machine idle tracks. Later, you do not have to be synthesized occupy these effects, directly from this remove the effect signal to the audio track, the effect can be used for other purposes.

2. other special effects

This mainly refers to electric guitar, electric times Division or synthesizer special effects processing, including compressed extension code, limiting distortion, dynamic filtering, sound stimulation, etc. Of course that this effect is used in other sound sources is feasible, but it changes to the original signal is very large, easy to get the original signal processing. Just as the electric acoustic vocal music generally do not have, so you can do various depth distortion effect processing, but does not feel awkward.

On the source of a variety of effects processing, address the effects of treatments and features a very understanding and be able to clearly identify, in order to properly adjust, not himself inexplicably, I do not know where is the problem. Here, you will need to pay attention to the following cases:

(1) frequency compensation easy to make a wide range of musical instruments (such as electric piano, synthesizers) imbalances in scale and pronunciation. On such sources of excessive frequency compensation proposal, and compensation of characteristic curve should be straightened.

(2) most of the chorus, reverb processing has a frequency modulation components, it can make the original sound pronunciation "tune" phenomenon, which is the very tip of the ear, a professional actor, it is easy to detect. Recommendations in the original signal is recorded in the lower or turn off these effects.

(3) chrome handle can change sources of sound obvious, that such a change and frequency balanced effect almost, but not with frequency balanced manner. Tuning two I processing experiments should identify clearly the effect.

Karaoke recording process

(1) singing are required prior to recording songs for karaoke laser discs or VCD disc, commonly known as accompaniment audio sources.

(2) the recording of the song was later sings music recording to multiple track digital recorder of the tracks, if sound accompaniment must be divided into two-channel recording. Min track record can make multiple recordings and choice, so that the next time will be fragmented editing and adjustment is not satisfactory in part.

(3) after the completion of recorded music, the singer will enter the Studio to sing some of the recording process, sniffing the recording microphone and headset at the singer was a suitable location, via the intercom system to communicate with the singer, the accompaniment of music by listening to headphones (be sure to select closed-end monitoring headphones, otherwise the accompaniment will be recorded in the singer's orbit. ) Gave the singer.

(4) at the same time, the recording in the recording process, through their large glass screen (or video) and sound reinforcement is to provide professional guidance and singer, thus improving the performance of the singer.

(5) finished singing some recording, recording the music for the idea, and singing parts mix, mixing is divided into two parts, one is on the music accompaniment for EQ adjustment, if you are a Mono's accompaniment by some software or effects processing, simulation of a similar sound accompaniment, the second is the voice of the singer and the effect of treatment of, first, to adjust the sound part, EQ and compression adjustment to satisfaction, and then add effects, add an effect to many of the practice, select suitable for the integration of unified effect, so that the completed work will generally achieve professional production level.

More on audio technology introduction of preliminary, in the hope that students study and recording technology-related books and materials, recording practice, audio recording in slowly understand technology and art, record a good works.
