Joerg Mueller (nexyon) added a comment to T47358: Sound is disabled by default.

With respect to enable/disable, we could make the following change: Add a choice between enabled, disabled and automatic and for automatic determine whether the scene has sound or not and enable automatically in that case. The choice of codec is a different problem, but a default codec for each file format shouldn't be difficult to choose.

Fixing this with a workaround by disabling JACK Transport functionality during rendering. Thanks @Bastien Montagne (mont29) for the help on IRC. A proper solution would be blender supporting animation playback during rendering, but I guess we are far away from that. ;-)

Joerg Mueller (nexyon) added a comment to T50240: Rendering crashes when synced to JACK Transport.

So yeah this is happening. I managed to fix the bug by preventing the sound system to change the current frame (cfra) and start/stop playback while rendering in an ugly way (if WM_jobs_test(wm, scene, WM_JOB_TYPE_RENDER)). The problem atm. is that I can only do these tests in the user interface, but not in sound.c of blenkernel, so if playback is started via jack transport while rendering, sound starts playing in blender and you don't have a way to stop it at the moment, ideally it would be completely ignored during rendering. To fix this I have to find a way in sound.c to find out whether blender is rendering right now (having access to a Main*). Can you help me with that @Bastien Montagne (mont29)?

Yeah, I could set the starting value to 0, then every strip gets an automatic fadein at the beginning, but not when seeking (this includes Blender jumping back to the beginning of the animation when it reaches the end), so in any case the solution won't be perfect. :-/ A nice solution that I have in mind requires quite big changes in the library, that are planned for audaspace 2, that I haven't started coding yet.

I'm currently a bit unsure if this is a limitation or an actual bug @Aaron Carlisle (Blendify). Reading so far, the solution with the interpolation for audio buffer chunks sounds like what should be implemented right now, but I could be wrong and need to check the code better. Afair there is even spline interpolation in the code. @Olly Funkster (Funkster) can you just post the diff of what you did and then we can work together on a proper solution? Thanks!

Joerg Mueller (nexyon) added a comment to T49241: Consolidation of FFmpeg/Audio Options.

Hmm yeah, we could change that. At the moment for playback inside Blender the user preference settings are used. Ideally people would get the preview of how it would sound after export, so we could use those settings. The problem is that in the end you're always forced to use the user preference settings as maximum as you can't play 5.1 sound through stereo output or 96 kHz through 48 kHz output obviously...

Joerg Mueller (nexyon) added a comment to T49241: Consolidation of FFmpeg/Audio Options.

The reason behind this is, that the Audio settings (first screenshot) are independent of the encoding and important for the playback not only the encoding of a scene. They are mostly unrelated to ffmpeg settings, unlike the Encoding settings (second screenshot). Asking to put for example volume under Encoding is as if you would do the color balance of your images in the export settings. If we do something it would make sense to remove the extra volume setting there, leaving the only two settings that are encoding related: codec and bitrate.

Joerg Mueller (nexyon) added a comment to T48888: Audio added from video is not scrubbing or playing back synced in VSE.

Very interesting behavior. The silent part in the beginning of the audio is always skipped when playback is started (that means, actually starting playback, scrubbing or moving the cursor during playback) at that position. If playback starts somewhere in the non-silent part it works. The problem is caused by FFMPEG not seeking properly in the silent part, which unfortunately means, that we can't fix the bug, it has to be fixed in ffmpeg.

I'm running Arch linux and can confirm the issue. It's with libsndfile actually which reports flac files as not seekable when opening the file [1]. Interestingly the seeking works nevertheless, but Blender does not do it when libsndfile reported that seeking doesn't work (for obvious reasons).

This is probably not a bug. The speaker positions are not exactly at +/-2 as this would be back center - the panning value basically gives you the direction where the sound is coming from if you multiply it by 90 °. For example: 2 * 90 ° = 180 ° = exactly from the back.

Joerg Mueller (nexyon) added a comment to T47627: Audio will not keep sync with video at 20 FPS..

Just based on the comments it seems like the bug is caused by the missing frames in the source file. During playback blender respects the PTS (presentation timestamps) in the video and is fine, but during rendering the output, blender just uses the next frame every time, ignoring the PTS and thus time compressing the video. To test this, you could simply use ffmpeg to reencode the video, to fix the missing frame issue and then try again to use this video in blender.

Just to clarify: this message is printed by OpenAL soft and cannot be suppressed in the blender code. I think switching to 48 kHz as a default is the best solution and that's what the committed fix does. I was worried if we get the opposite error message now, with hardware only supporting 44.1 and not 48 kHz, but according to [1] this does not seem to be the case. In any case 48 kHz seems to be the superior default when I looked up the alternatives [2].

Joerg Mueller (nexyon) updated subscribers of T46886: VSE: .flac sound file (only generated by Blender) show as clip length = 0.

I just talked to @Sergey Sharybin (sergey) on IRC and he told me that the official builds are built with libsndfile disabled, so it's ffmpeg causing the issue after all. Will try later to build blender with disabled libsndfile and check if I can reproduce the bug.

Very interesting, just like the other bug, I can reproduce the problem with the official build but neither with my own nor my distro's (Arch) build. A flac file export is using libsndfile and not ffmpeg. Are you using the official build or the blender version coming with Debian? Either way, can you check if the bug appears with the respective other versions as well?

Nah, 1.6.0 is old, 1.16.0 is the current version.

Joerg Mueller (nexyon) added a comment to T46683: High pitch sound artifact on import of 48k audio.

Yes, during playback the aliasing (not antialiasing...) will be there. It will be removed when rendering output video, yes. And as I wrote in the commit log, playback uses low quality resampling because of performance.

Joerg Mueller (nexyon) added a comment to T46683: High pitch sound artifact on import of 48k audio.

Yep, those additional peaks are the antialiasing I talked about. With the current Blender version you will have to downmix the audio and multiplex that to your video by hand.

Btw: Audio mixdown does high quality, but normal animation rendering does not, that's indeed a bug, will fix in a second!

I know you don't want to hear it, but this is not a bug of Blender. xD

I could reproduce the bug with jack and old (default) audaspace. Are you using Jack on purpose?
