Question: is it stereophony or monophony if what comes out of the left speaker is identical to what comes out of the right speaker?
Uh, i dont understand a little bit. Monitors are stereophonic, i think mono is only from one source of sound, so the single monitor. If we have two monitors playing the same from one or two channels it will be already stereo, but heard as mono, until making any changes in the channels, then stereo. But im not a pro in this matter
I guess the answer to my question is "it depends" ...
I copy and modifiy part of the comment I deleted:
The
"true" monophonic sound file = a sound file containing
only one (mono) track that will pass through one (or more) speakers.
The
"false" (or "doubly true") monophonic sound file = a sound file containing
two identical (mono) tracks (or one with sound and the other with silence if you have a 100% L or R panned) that will pass through one or more speakers, but usually two, one for the left speaker and the other for the right speaker (so your sound file is unnecessarily heavy, it weighs twice as much as a truly mono audio file). This sound file is stereophonic, but what you ear is monophonic.
The
stereophonic sound file = a sound file containing
two different (mono) tracks, that will pass through one or more speakers, but usually two, one for the left speaker and the other for the right speaker. This sound file is stereophonic, and what you ear too.
As LMMS exports your project to a file containing two tracks, you can’t obtain a "true" monophonic[/b] sound file with LMMS.
The
C*Narrower with strength = 1 is the fastest way to obtain monophony (place it last in the EFFECTS CHAIN of the master channel).
To verify that the C * Narrower allows to obtain a monophonic signal, you can use a
goniometer (I use EasySSP that you can download here
https://au.tomatl.org/ ).With the goniometer (left frame in EasySSP), monophony = vertical
line.
To verify that the C*Narrower allows to obtain a monophonic signal you can also use
Audacity:
- export your LMMS project with the C*Narrower,
- import your file in Audacity (so one audio file containing two tracks),
- in the audio file, click on the bar containing the name of the track,
- select Split stereo to mono,
- select one of the two split tracks,
- in Effects, select Invert (this inverts the phase of the track selected),
- click on Play : you do not hear anything,
- select your two tracks, and in Tracks, click on Mix and Render: you get an audio file containing one silent track (it's flat, there is no waveform).
In one of your projects, to check what part of your signal is stereo :
- import one of your file in Audacity,
- in the audio file, click on the bar containing the name of the track,
- select Split stereo to mono,
- select one of the two split tracks,
- in Effects, select Invert (this inverts the phase of the track selected),
- click on Play : if you hear something, what you hear is the stereo component,
- select your two tracks, and in Tracks, click on Mix and Render: what you see is the difference between the L and R channels.
