How to turn mono sound into stereo. How to turn mono into stereo
In this article I will talk about.
I want to warn you right away. It is impossible to adequately turn a full-fledged mono track (song) into a stereo track. This is fraught with the appearance of various phase distortions and undesirable effects, especially on low frequencies. Therefore, I will not consider this issue.
It’s another matter if any recording sounds only in one channel (right or left). I often came across such recordings on the Internet (audio podcasts, recordings of webinars, interviews). Listening to them with headphones, you see, is not very comfortable (the sound is only in one ear). Or if you are recording vocals or playing live instruments, then in this case it makes sense to convert the audio track from mono to stereo.
How to turn a single-channel recording into a two-channel one
If you have downloaded some single-channel audio recording (podcast, webinar recording, interview) and want it to sound in two channels, then by following a few simple steps you can achieve desired result. Any audio editor, for example, is perfect for these purposes.
1. Launch the program and open required file File/Open (Ctrl+O)
As you can see from the screenshot, audio is recorded only in the left channel.
2. Separate the right and left channels. To do this, go to the track menu and select the item Split stereo track
3. Copy audio from the left channel to the right. To do this, select the left channel with the mouse and press the key combination Ctrl+O. Next, select the right channel and paste the copied audio Ctrl+V.
4. Combine the two tracks into a two-channel recording. To do this, in the menu of the first channel, select the item Make stereo track.
This is what happened.
Now we see that audio is present in both the left and right channels.
5. Save the result in MP3 format. For this we choose File/Export, indicate the path where we want to save the file and its format.
How to make a stereo recording from mono
If you recorded a vocal part or part of an instrument (guitar, saxophone, etc.) in mono, but want to make it sound in stereo, then I recommend using the double track effect. Read about how to create this effect in the article. .
However, this is not the only way to achieve stereo sound. A similar effect can be achieved using plugins based on signal delay. This, and
In this lesson we will learn how to Adobe Audition turn a mono file into stereo. It often happens that this becomes necessary, both when recording music and when editing ready-made audio files created, for example, by cameras, voice recorders or video cameras - it doesn’t matter. The only important thing is that some kind of stereo effect needs to be introduced into this sound... And for this, the audio needs to be converted from mono to stereo.
Turn on Adobe Audition (I'll use version 3.0) and switch it to editor view with the key 8. Loading the experimental mono file into the audio editor window File → Open
and click (regardless of the audio editor version) F11. A dialog box appears in which, in the option Channels(channels) set the switch from Mono V Stereo and press Ok. Our entire file is then converted from mono to stereo.
Let's start an experiment. Let's say we wanted to hear the sound of a hall, a hall - we go to the most common stereo effect - reverb. There are several types of them in Adobe Audition. Let's use, for example, Effects → Reverb →, a corresponding dialog box appears, where we select one of the proposed presets (or create our own parameters), and we get something like the following sound:
Audio clip: Adobe Flash Player (version 9 or above) is required to play this audio clip. Download the latest version. You also need to have JavaScript enabled in your browser.
...Or we wanted, for example, to recreate the sound of a canyon or a city square: let's move Effects → Delay and Echo → and adjust individual parameters for each channel in the settings: effect levels, number of repetitions, delay time, “coloring” the delay sounds to the desired timbre...

Want a scary choir? Come in Effects → Modulation → Chorus, and set the modulation depth (Modulation Depth) and the number of voices more...

...Or do ping pong in Effects → Stereo Imagery → Pan/Expand, by drawing a “winding snake” in the effect diagram and clicking Ok.

Resolution is the number of bits used to represent sound. The file resolution can be increased or decreased. Increasing the resolution does not change the sound quality, but allows post-processing to be performed with greater clarity. high accuracy. However, reducing the resolution of the file results in an audible distortion in the sound called quantization error.
1. If you want to increase the resolution, open the file with a small(8-bit) resolution. If you want to reduce the resolution, open a file with a higher (16-bit) resolution.
2. From the Processing menu, select Resolution Converter. The Resolution Converter dialog box appears.
3. In the dropdown listResolution select the desired value.
4. If desired, select necessary settings in the dropdown list Dithering.
The Dither value determines the random nature of the dither (generated noise) used to mask the quantization distortion that appears when the file resolution is reduced.
5. Select a type if desired Noise processing.
The Noise Process value determines the acoustic positioning of the quantization noise. With its help, you can shift noise to those ranges that are less perceived by the human ear. It lowers the audible noise floor and makes the audio file appear as if it has been denoised.
Note: When increasing the file resolution, the Dither and Noise Processing values should be set to None and Off, respectively.
6. Click OK.
Mono/stereo channel conversion
You can convert files from mono to stereo and from stereo to mono.
Mono to Stereo Conversion
1. Open the Voiceover.pca file. This file is located in the same folder as the program itself.
2. Channels and select Stereo from the context menu. The Mono to Stereo dialog box appears.
3. Select radio button Two channels and click OK. Mono data is split into two channels.
Convert stereo to mono
1. Open the Saxriff.pca file. This file is located in the same folder as the program itself.
2. Click right click mice in the field Channels and select Mono from the context menu. The Stereo to Mono dialog box appears.
3. Select radio button Mixed and click OK. The left and right channels will be combined into one mono channel.
We all understand that in order for our music to sound acceptable on different equipment, we need equipment that will be more or less honest with us. BUT! Even if you have the best studio monitors in your room and the room acoustics are great, you may still be forgetting about one important point… Does your music sound acceptable in mono? Are you sure that if you mix on stereo monitors or headphones that your mix will automatically sound great in mono? Why should I even worry about this, the whole world has been living in stereo mode for a long time... Ku-ku!?
Firstly, of course, millions of people still listen to music in mono, anywhere... They are simply forced by the will of fate). Many people have a portable radio or receiver, a miniature boombox or, in the end, one speaker at work. In cars, radios often play exclusively in mono, some establishments and even clubs present us with music in mono, and even the Internet, it would seem, last place, where I expect a setup on this score, also often plays mono for us (audio or video players).
So, people will hear your music in mono sooner or later. And here you don’t know what your brainchild will sound like, and I think you probably don’t care). If you don't mix or even check your mixes and mixes in mono, now is the time to START! And I’ll say with confidence, if you haven’t checked how your mix sounds in mono, then the worst option is really the worst, it can really sound, let’s say, "not good" This can easily be affected by your stereo base in the mix, (the overall picture of the panorama (pan) of all components (tracks) of your mix in) which may not even be spread out too widely, as well as phase damping, this is when, for example, two inverted phases (reverse each other) merge and the result is either a weaker signal or no signal at all. And if you’re really interested, then conduct an experiment with two sinusoids of the same frequency, set the phase start parameter for the first to 0 and for the second to 180 - and play them back together - dead silence. And the chances of such substitutions in your track may be thousands, or even more... Therefore, let's now move on to solving all these risks and problems, it's scary)
How can I check in this mode?FLStudio? It’s just something that hasn’t happened before... Well, in FL Studio, although there is no such direct line yet function button activating mono mode for a mixer track, but there are a lot of ways and a bunch of plugins to convert a stereo track to mono. So, here they are in front of you...
Turn the Stereo Separation knob all the way to the right (in my case on track 1, but if you want to hear the entire track in mono, then do it on the master track). This will combine the two separate channels Left and Right into one single mono channel and give you the whole truth about your track.
If you're having trouble doing the first step and you're still processing the master track Maximus plugin, then it, as ordered, has the same Stereo Separation knob and it should also be twisted to the right until it stops.
And finally, there are hundreds of plugins, processing effects for working with your stereo base and more, which can dry the stereo base up to full mode mono, as presented on this wonderful and simple plugin BT Stereo Imager. This fader needs to be moved all the way to the left for mono mode, the reverse direction is an extension of your stereo base.
So there you have it, plenty of ways to test your mixes in FL Studio, in mono mode. And if it sounds really unacceptable, and I mean, some instruments, maybe even at least at some certain moments, are not audible or sound too muffled, or another option is that the whole mix sounds very blurred and unclear - this you need to fix it. There are several solutions here... First, you need to listen to the widest panorama of tracks and instruments in mono mode (I’ll trust your hearing here, if you don’t understand what I mean, then check each one) And find out which ones sound muffled, unclear and unacceptable - move those tracks by the Stereo Separation parameter at least 30-40% towards mono (i.e. you listened to this track at the 100% merged parameter - now do 30 or 40% merged this will give more cohesion to the stereo image of your track, and the same with the rest of the tracks that don't sound right.
And if the problem is not solved after all the operations performed, then now is the time for heavy artillery. Working with the phase of the tracks in your mix. In order to correct phase overlaps and substitutions, you need to try this operation with each track (but always one track at a time!)
Listen to all the tracks simultaneously in mono on the master while you try to activate this Reverse Polarity option with each track. This inverts the phase polarity of the selected track by 180 degrees. And there will be a moment when that destructively dull instrument or track will sound much better and more suitable.
Here is an armor-piercing set of solutions for your mixes and your mixing, so that your music really sounds great EVERYWHERE on any equipment and you are always calm about the result and can sleep soundly at night with a clear conscience!
And now the most important thing for the future... From now on, make it a habit to either mix in mono or check your mix in FL Studio in mono at the end of the mix session. This will insure you against very unpleasant consequences in advance. That's all, good luck and great success in your work!
