Summary0000326: A way to set an audio track to "left", "right" or "middle (mono)"?
DescriptionWould it be possible to add some way to set an audio track to "left", "right" or "middle (mono)"? I can use "Audio -> "Map 1:1" to set two audio tracks to "left and right". But if I want something else, for example only one track to the right, or all tracks to the middle (mono), I must do it using a mouse in the small rectangle window in the left panel, which isn't very precise and I am never sure if it's exactly "left", "right" or "middle".

Oh, you already sent a post in the meantime while I was doing research here and writing the new post.

Hi @Michi,

- Did you get an email when you signed up for the forum?
- Did you reset your password as it says in the email?
- Are there any script blockers active for the Cinellera website, if so can you disable them for our site?
- Are you using the same email address for the forum as for the Mantis bug tracker?

If it is indeed the same email address, I see that you are present in our database, however it seems that you have specified a different username in the forum than in Mantis bug tracker. Could it be that you are trying to log in to the forum with the bug tracker name?

@Michi
Thank you. I don't know if you are subscribed to the forum. In order not to overstretch this thread with OT topics, I've opened a post in the Audio Editing section of the forum for anyone interested in the discussion.

Hallo,
I have found the error: For the right channel you can't just insert this effect: L_Mono to Stereo splitter.
I have to insert it like you showed.
Then everything works out fine.

Do you know anything about compressors? That is currently still my main problem with Cinelerra.

@Michi
For me, L_Mono to Stereo splitter works well.
Are you sure you are using it correctly?
I have made a little video that shows you how to use it.

00:00:05 When you read it, you can see (white frame) that there is nothing in the right channel.

00:00:41 When reading, you can see (white frame) that there is the same content on the right channel as on the left one.

@fary54 and @PhyllisSmith
because "L_Mono to Stereo splitter" does not work for me at the moment, I do it this way:
Switch off the right channel or delete it.
Left channel: Set pan so that the the green dot is in the center so that the red speakers show 1.0 is visible on both sides.
it looks like it will work well.

Thank you both
Michi

@PhyllisSmith
Thank you for your commitment.
Unfortunately, when I insert L_Mono to Stereo splitter on the left track, nothing happens. What can I do better there?

@PhyllisSmith
Personally, in this case, I don't change anything in the format menu and nothing in the patchbay either.
As @Michi explains, if the right channel is recorded 20 dB lower I simply place:
- an "L_Mono to Stereo splitter" filter on the left track.
- the shared effect "L_Mono to Stereo splitter" from the left track to the right track

So I stay in stereo for cinelerra but, of course, when listening, I'm in mono.

'So how can you use only one (e.g.) the left one in Cinelerra?'

I have zero audio skills when it comes to audio in Cinelerra, but there are some easy ways to manipulate the channels.
1) the Settings pulldown, has an option called "Format". You can move the red colored speakers around or change how many there are.
2) in the Patchbay, which is the area all the way to the left in the main timeline window, the 4th symbol from the left (looks like a right facing speaker) can be clicked on to 'Don't send to output" to temporarily disable playing that channel.

Hallo,
yes, it would be wonderful if you could copy the left audio channel to the right. Good microphones sometimes have a safety channel in case of overload: the right channel is recorded 20 dB lower.
So how can you use only one (e.g.) the left one in Cinelerra?

Today GG started to see what this is all about and whether or not he can implement something. With limited understanding how the Audio speakers are currently working in the code and at least 1 broken speaker here, not sure of the outcome. Stand by for a further update.

Yes, a right mouse button menu is maybe the simplest solution.

If possible, another idea could be ...
1. RMB (Right Mouse Button) on Pan icon. (And here the RMB function would be appropriate)
2. A PopUp menu with 9 options is showed:
- Left Top
- Left Middle
- Left Bottom
- Center Top
- Center Middle
- Center Bottom
- Right Top
- Right Middle
- Right Bottom
3. And you choose by the list.

These magnetic points are a good thing and very popular with video editors. I like to use them myself.
If you briefly pick up a magnifying glass you can see that an exact positioning can be read from numerical values. But we have to keep an eye on the other channels as well, like 5.1 and 7.1, etc.

I was thinking about some type of "magnetic" points in the pan rectangle for the left, right and center position for easier pointing and to be sure about the exact position. Or some other simple tool or dialog box outside of the rectangle to set the "left", "right" or "center" position for each individual audio track.

In the first turn, the zoom could be increased from currently 100 pixels to 160 pixels.
In addition, the font should be slightly enlarged and, if this is not sufficient, provided with a high-contrast semi-transparent background.
