To close the question, here’s an option how to generate a 440 Hz tone 
for 2 channels: https://www.datafilehost.com/d/d67b7b18

Ugin, if you want there is an alternative, without rendering.
Take a look at:

So it can be more flexible to change the frequency when you want, if you 
needed.
Audio1 is the master and it is shared with Audio2. Then you can change 
only the seetings of the effect on Audio1; Audio2 effect is "child" of 
Audio1.

Very nice layout with the different windows of Cinelerra, also 
interesting how to use this effect. Thanks for sharing.

For aeval, note the playback buffer sample.  And in case you can not see
the png file, you will see with the aeval setup, the default is 440 +
something else, so remove the something else to get just the 440.

Yes, all right. Thank you.
I have not figured out yet how to connect both channels - left and 
right, but this business is solved.

[Cin] Waveform generation using ffmpeg filters

2019-04-13 Thread preobraz

Hello.

I'm trying to generate a 440 Hz sound with the help of FFmpeg of ffmpeg 
-f lavfi -i "sine=frequency=440:duration=5" test.wav type, but the 
waveform is: https://www.datafilehost.com/d/ea27d7ec
Does Cinelerra incorrectly process the generation, or do I need to 
change something in the settings?
