How to apply sound to sound: several basic techniques and applied programs
Many of those who try to create their ownprojects in the format of audio or video, often faced with the problem of how to superimpose one sound on another. It can be, for example, recording a vocal part on an existing soundtrack or normal mixing of tracks. Very often such operations need to be done when creating various multimedia presentations or similar projects.
In principle, there are several methods that allowto carry out such actions, even on a professional level. But the discussion of the most frequently used techniques will begin with the simplest, and then we will consider even more complex ones. However, in this case, initially the solution to the problem of how to impose a sound on music implies knowing the corresponding software at least at the initial level. But first things first.
How to apply sound to sound: basic methods
As for the instruments used, the insertion of an audio file can be performed quite simply in any office editor (for example, the Power Point program will be considered below).
But when it is required to solve the question of howput sound on sound or audio on video, without special editors can not do. Among all that you can use, you can separately distinguish the following software packages:
- audio editors (Adobe Audition, Sound Forge, Cockos Reaper, Acoustica Mixcraft);
- sequencers (FL Studio, Presonus Studio One, Cubase);
- video editors (Sony Vegas Pro, Windows Movie Maker).
How to apply sound to Powerpoint?
But for an initial understanding of inserting audio orThe addition of sound is separately worth considering a popular office application for creating Power Point presentations. If the user understands this program in terms of completing documents with multimedia elements, then you can begin to master more complex applications.
So, how do I put sound on slides?At first it is desirable to copy the audio file directly to the program folder. After that, multimedia is selected from the insertion menu, and audio is set as the format. After selecting an object, you will be asked to specify exactly when the playback should begin (you can choose at will by clicking or automatic mode).
If you want to get continuous playbackaudio in the settings for working with sound, you should set the appropriate option. To play a sound file with several slides displayed, an animation section is used in which the effect settings menu and the Stop after ... option are selected, and then the total number of slides for which the selected audio track is to be played is specified.
Using audio editors and sequencers
If the presentations are more or less clear,you can move on to more complex tools. Consider the question of how to superimpose sound on a sound, using the Adobe Audition editor as an example (in other programs the technology is practically the same).
First open the editor, go to the modemultitrack recording and editing, select the first track, and from the file menu use the command to open the desired file. Next, select the second track and perform the same operation (and so on for each track). In principle, you can open files in turn in the main mode, which is used to edit a single file, select it completely, copy it, and then insert it into the desired track in multitrack mode.
Now the tracks will sound synchronously at the startplayback. If you want to make a cross-sound (the Crossfade effect), you can simply move the desired track to the desired number of positions on the timeline. To attenuate or increase the sound for each selected track, you can apply Fade Out and Fade In effects, previously selecting the desired area of the sound track.
In sequencers like FL Studio, the desired audio fileis sent to the corresponding track, after which the sequence of the sound is set by the pattern in the playlist using the Song playback mode (by default, the playing mode of one pattern is set).
In other applications, you can immediately create audio tracks, and then either insert the selected files into them, or record vocals or live instruments (with or without additional soundtrack).
The technique of sound overlay in video editors
Similarly, the question of how to superimpose sound on audio or audio on video is easily solved in video editors.
In each such program there is a bottomA special timeline, which simply drags video clips and selected audio files. The principle of superposition and overlapping at the same time resembles work in PowerPoint and audio editors. If the audio editing application does not support (for example, Movie Maker), you can use external tools for processing (the same Adobe Audition). But most professional utilities like Sony Vegas Pro are equipped with such means.
Now a few words about processing. Suppose a user needs to make sure that all audio tracks in the final export, for example, to an MP3 file, sound at the same volume or even when there are fragments with a volume too low or too loud.
For this you can use the toolnormalization. In Adobe Audition, after saving the project, go to edit one file, select the content and then click the Normalize button in the menu on the left. In the same way, you can easily apply different kinds of effects like an equalizer or compressor, which will create a more interesting and warm sound.
If the user skills use suchprograms does not have, you can install an automated application for the final processing (AAMS - Auto Audio Mastering System). Its advantage is not only that the user's participation here is limited only to the choice of the template and the file to be edited, but also that you can create the template yourself, for example, by initially selecting the composition of your favorite group. After that, the custom track will be processed in accordance with the sound characteristics of the original composition of some artist.
It remains to add that the most optimalthe option of imposing sound on another sound, and on video, and on graphics in the form of slides, is still the use of audio editors, especially since most of them can work with video when the import function of the appropriate format is activated. In addition, with their help you can even extract audio from the video, and then apply for your needs.
