Joerg Mueller (nexyon) updated subscribers of T66786: Video editor Sound muted without muting it.

Okay, from what I gather from both of you now is that OpenAL works, but SDL does not on Windows. @LazyDodo (LazyDodo) can you check if SDL works on windows or if it's not? Maybe we need a library update on windows?

Joerg Mueller (nexyon) added a comment to T66117: Sequencer Scene Strips' Input(3D/Sequencer) and volume and has no effect on audio..

That would be really nice! I'd love to see sound_update_base and BKE_sound_update_scene gone. The biggest issue here is animation. Whenever some audio animation (volume, pitch, etc.) changes, all affected frames need updating. If that's possible with the dependency graph, that would be ideal! E.g., if an animation is changed by modifying the f-curve, that parameter needs to be updated for all frames that now have a different value.

What happens if you open a file that has AV-sync set? There you'll have the same behavior still. Or you set the synchronization to something else, which might not be what the user wants. I'm a bit hesitant in changing stuff without letting the user know. Especially, I would expect a file not to change if I only open and save it - independent of my user preference settings.

Joerg Mueller (nexyon) added a comment to T62653: Crashing with animation rendering and sound.

Nice find on where the problem was introduced! I'd be fine with the temporary fix. Are you sure that this doesn't prevent both calls of the two threads during rendering? One should still be done. I'm not sure what moving to the dependency graph will change here, does the dependency graph get updated from two threads as well? Or is it two different instances and thus as you said viewport and renderer each need their own sound_scene instance?

I tried to reproduce the crash, but it also didn't happen on my linux. Given the stack traces though, it looks like the issue is BKE_sound_update_scene being called at the same time in different threads. As such a mutex in this function should solve the problem?

Joerg Mueller (nexyon) closed T48505: VSE audio pitch changes the speed of the audio as Invalid.

@Hossein Shah (hk1ll3r), you're right the strip length stays the same, but that doesn't mean that the speed doesn't change. If you have a strip of full length (not cut on any side) and you change the pitch to 2, you'll end up with double pitch and double speed, but the strip will stay the same length, meaning that it's silent in the second half. We intentionally don't change the strip length when the pitch is changed, since this can cause many problems, especially when you animate the pitch. I hope this clarifies the issue. If not, please ask further questions on devtalk.blender.org as @Sergey Sharybin (sergey) suggested.

Joerg Mueller (nexyon) added a comment to T58153: Preview mono audio not the same as render.

So my suspicion seems to be correct. The difference in playback is cause by the changes in OpenAL soft which now uses ambisonics (https://en.wikipedia.org/wiki/Ambisonics) based surround sound. Originally, I implemented Blender's speaker mapping based on OpenAL soft. That's why so far they have been the same. Ambisonics is actually better and ideally Blender would also go this direction for 3D sound. Unfortunately, I don't have the resources for this development right now, it's more a long term goal. If you need an short term solution, please use the configuration files as I have mentioned them. There are also ambdec files for different speaker setups including 7.1 here: https://github.com/kcat/openal-soft/tree/master/presets.

Hmm, SDL should work though, can you play around with the settings a bit? The sample rate 48 kHz should work fine, you can try changing the number of channels in the user preferences. Also please try setting the environment variable SDL_AUDIODRIVER to dsound or waveout and check if that helps to get SDL to work.

Sorry for the late reply, it's been a busy month, but now there are holidays :) The noise problem sounds weird, especially since you're the only windows user reporting it.

I guess this change needs more evaluation. If the change targets video encoding, I don't see on what basis the changes in audaspace are necessary? Does audio en-/decoding actually benefit from the changes? It also seems a bit random to have those changes for playing audio files and mixing down audio, but not for decoding videos (within movie clip editor or VSE)?

Hey! Thanks for reporting the warnings! I'm not sure what to do about the macro redefinition. That's of course mainly a problem in the SDL source code - did you report it there or submit a fix? Your solution is certainly too broad of a workaround since it silences all those warnings even if there are legitimate ones in audaspace's code.

Hey, thanks for the update! I tried it and it works really nice for strips with constant pitch. However it doesn't work for animated pitch at all. I think we should go a middle way and don't touch the strip length when the pitch is changed at all. Otherwise we get serious problems with animated pitch strips. The code for cutting and drawing would work fine, but we would have to remove the other changes I guess. Can you try strips with animated pitch? The goal is that the strip start and end don't change during playback.

Ok, so the first problem is, that the display of the pitch scaled waveform is wrong in D3496 when the start is not 0. Changing the start on pitch change is also wrong, since the start of the playback of that strip doesn't depend on the pitch. So to keep the sound start at the same position when changing the pitch, you shouldn't do anything, because that's what happens right now.

I'm not sure if the fixes are necessary for the 2.7x series? The fixes certainly make sense for 2.8 and there might be even more changes that we should make here, since a lot of the ffmpeg functions we use are marked deprecated already. Internal audaspace is not used in Blender 2.8 anymore, but we can certainly apply these fixes if we want to support ffmpeg 4 with blender 2.7x. For 2.8 I'll fix audaspace together with the deprecated ffmpeg function calls as soon as my distribution releases the ffmpeg 4 update (currently in staging).

Joerg Mueller (nexyon) added a comment to T54418: VSE: audio clipping/distorted after render.

If your source audio file isn't using the full dynamic range of the amplitude, it is basically wasting quality. Most audio files have a dynamic range of 16 bit. If you have to double the amplitude (volume in blender = 2), you are already wasting one of these bits. At 10, you are already wasting more than 3 bits. So for any recording engineer the goal is to utilize the whole dynamic range to not lose any quality during recording. When you have a file that doesn't use the full dynamic range, then increasing the volume in audacity instead of blender doesn't make any difference in terms of outcome, so you could just do it in blender directly. The problem is of course that you don't by how much, so using audacity makes sense after all. As soon as you normalized the volume in audacity, you are using the full dynamic range, going higher in blender then leads to clipping.

Ok, there is a lot going on here and a lot of the information written here is just plainly wrong. Let me try to summarize: you're setting the volume of an audio strip to 10 and get an output that is clipped. Well, that's expected. I tried this and whatever I do, it always sounds the same - whether I play back in Blender (SDL or OpenAL), mix down (wav or flac) or render to a video (matroska, PCM). In that sense, I cannot reproduce the bug report.

Your distinction between the three types of settings is pretty clear. Regarding the user preferences there is no discussion, they are stored system wide and not blend file wide. Playback will always have to happen within the bounds of the user settings. For example, if your user settings are stereo, you simply can't playback 7.1, it will be mixed down to stereo, as in @Christopher Anderssarian (Christopher_Anderssarian)'s laptop example.

Joerg Mueller (nexyon) closed T53887: Audio keeps playing even with negative frames as Archived.

Hi, thanks for the report. This is a known problem - audaspace doesn't work with negative timings. The reason for this is that blender itself wasn't really designed to work with audio - to overcome some of these problems, I had to make some design decisions that ended in not supporting negative timings. The alternative would have been to not support animation (of volume, pitch, etc.), which is definitely the worse alternative. We could at least document somewhere that negative timings don't work with audio?

Hey @Sergey Sharybin (sergey) I just checked the build bots, while the 64 bit linux builds still fail, I checked both 32 and 64 bit and they now both have WITH_CODEC_SNDFILE as ON. So we can consider this resolved?

Thanks @Sergey Sharybin (sergey) ! With libsndfile disabled I can reproduce the error with ffmpeg.

Joerg Mueller (nexyon) added a comment to T52488: Linux - Audio Mixdown - flac audio isnt created correctly.

I just saw that the buildbots build without libsndfile, so the cause could/should be ffmpeg. Do you build with libsndfile @Carlo Andreacchio (candreacchio) ?

Ok I can reproduce the bug with a buildbot build, but it's not a debug build, so it's hard to track down the error. @Sergey Sharybin (sergey) can you help? Which linux is the buildbot running and which ffmpeg/libsndfile version? Is it a self built one? Can I get it somehow?

Joerg Mueller (nexyon) added a comment to T52472: VSE Audio Volume not set immediately.

This is because audio volume changes are always faded and the initial volume is 1.0. The bugfix sets this initial volume to 0.0 so that it's more a fade in. Meanwhile you can try to set the mixdown "Accuracy" to lower values than 1024. This will make it take longer for the export (1 would take VERY long, I'd start with 128 and keep halving that) but if the first few samples of your sound file are not too loud, this can help.

I can't reproduce this bug. Can you tell me which distribution and version you are on and how you get blender? Official builds, distribution builds or self built? I guess it's a faulty ffmpeg version that causes this, probably not much we can do.

Joerg Mueller (nexyon) abandoned D2716: Audaspace 1.3 patch for Blender 2.8.

@Julian Eisel (Severin), newer cmake is available in jessie-backports, also keep in mind Jessie is on it's way to EOL now, so you should consider dist-upgrading. Not saying i'm supporting such a rather silent and non-communicated bump of CMake tho.
What i'm not sure is: why do we need to specify std in audaspace? This is already done globally for the whole Blender [1]. WITH_CXX11 is default in 2.8 branch and it will fail to build if you disable this option. Eventually we'll need to clean this up and remove option all together, but that's another story.

The latest changes required for numpy paths to work on Linux and Mac! All build bots build this patch fine now, so I guess it's ready to push. Will do that tomorrow morning.
