Decide what you need an audio editor for. Based on this, you can understand what functions are needed:
- Noise removal – the program determines which sounds are unnecessary and deletes them. Sometimes human involvement is required.
- Restoration – for processing vinyl records, for example. You can remove clicks or rustling.
- Equalizer – adjust the volume of different frequencies. For example, in a male voice, lower frequencies are more pronounced. Therefore, they are louder. But if you remove all the high frequencies, there will only be a bubbling. Take away the low – the voice will become quiet and mechanical. Need a balance.
- free mp3 converter from youtube – convert and save an audio file.
- Effects: echo, distortion, delay and more. Most often used in music, but you can change the voice to your liking.
- Record or create sounds.
- Change the volume.
- Delete, drag and drop, copy, overlay and other similar functions.
If you are going to record podcasts, audio or video lessons, the simplest thing is enough – Audacity. But if you want to write music, you need complex professional programs like Cubase or Adobe Audition.
Most often, audio processing will be to remove unnecessary pauses and duplicates, remove noise, twist the equalizer and apply effects like reverb or compressor, so do not waste time learning complex programs without need.
What is real-time processing?
You have noticed that Sony Sound Forge and Adobe Audition have “real-time processing”. This is the most necessary feature for those who conduct webinars and often communicate on Skype.
The essence of the function is that you set the settings and apply effects not on the finished file, but right during recording. You can not start recording, but simply change the sound settings.
As a result, you will receive already processed sound without noise and with the desired frequencies.
Problems that cannot be resolved by processing
Sound processing is not a panacea. Sometimes you have to draw sound in other ways that depend on the problem.
Have you ever heard a noise like a metal rattle or a crunch of polystyrene? If something similar happens on your recordings with sound, then you have a microphone in the background. Perhaps somewhere around the case closes the contact, or maybe the problem is in something else.
It is necessary to find the location of the circuit and isolate the contact. If it does not help, ground the microphone. To do this, grab the microphone housing. There are three options:
- It will help.
- Nothing will change.
- It will only get worse.
If you have the second or third option – buy another microphone.
Another common problem is the sound from under the water. You say, but something with the voice is wrong. As if you are under water. Most likely you have loose contacts on the head or plug. Solution: if there is a soldering iron, repair; if not, buy a new microphone.
A normal microphone does not have to be expensive, because you can buy a good option within 1,000, 500 and even 150 rubles. This quality is quite enough if you do not record opera vocals.
The third reason is the most insidious. We talked about at the beginning is a dull voice. It is connected with the fact that you speak uncertainly or too quietly. Here it’s not a matter of processing or even a microphone. But this problem will be solved only with practice.
Classification of audio correctors
Users should browse through several application options to focus on the most relevant. Some of the offered editors are used to implement specialized tasks of a certain type.
But there are universal software products that are designed to help in more complex situations. The separation of functions is carried out in a specific classification. The first type includes digital corrections. Such sound workstations are complete utilities that can implement a huge number of actions. They help in working with a variety of music files and audio recordings.
They are aimed at implementing a full cycle of work on creating audio, subsequent recording, simpler and more complex editing. It is also planned to carry out work on mixing audio material. This is possible only if you use the already built-in modules or load additional plug-ins.
The second type is represented by MIDI editors. These are powerful utilities that can be used to edit MIDI music. The option of creating records is also possible. Most editors of this type are also tools for adjusting musical scores. So users are invited to perform various options.
Typical editors are represented by a third view. Such applications are used in those moments when you need to perform work at a simpler level. These programs are able to implement the processing of finished audio material. This is done in order to improve the quality of the recording used.
Also, users are offered another type of program, sequencers. These are independent programs that are designed to bring to life the most complex tasks when working with audio material. They can also be represented as third-party modules that need to be connected.
If the user needs to simulate the sound of certain instruments, then in this case you need to use the synthesizer that is available in each full-fledged editor. So most often users choose complex programs that really help to correct the recording and give it a new sound.
For simple file trimming, the same simple editor is suitable, of which there are a large number on the Internet. Digital editors or sequencers will be needed if there is a need to create a full-fledged musical composition.
