On the blender side this commit fixes importing video files with audio
and video streams that do not share the same start time and duration.
Differential Revision: https://developer.blender.org/D12353

The duration and start time for audio strips were not correctly read in
audaspace.
Some video files have a "lead in" section of audio that plays before the
video starts playing back. Before this patch, we would play this lead in
audio at the same time as the video started and thus the audio would not
be in sync anymore.
Now the lead in audio is cut off and the duration should be correctly
calculated with this in mind.
If the audio starts after the video, the audio strip is shifted to
account for this, but it will also lead to cut off audio which might not
be wanted. However we don't have a simple way to solve this at this
point.

This adds CoreAudio as audio backend on macOS.
CoreAudio is the standard audio API on macOS.

This adds WASAPI as audio backend on Windows.
WASAPI is the modern standard audio API on
Windows introduced with Windows Vista.

- NullDevice is now called None
- Automatic choice of best available device.
- Minor formatting, documentation and cmake fixes.

The issue was that sounds were always faded from 0 volume when they
started and depending on the currently used buffer size, the fading took
longer or shorter.
The solution stores whether the sound has ever been played back and
consequently does not fade when starting to play back.

Adds possibility to report progress during audio mixdown.

Port of the bugfix from audaspace upstream.
|
|
- Changing API for time values from float to double for better precision.
- Fixing minor mistakes in the documentation.
- Fixing minor unnecessary large memory allocation.
|
|
- Fixed uninitialized result used in DynamicMusic::seek().
The comment to this function says false is returned if the handle
is invalid, while in practice non-initialized value will be returned.
- Spelling typos in comment.
- Silence -Wdelete-non-abstract-non-virtual-dtor warning.

Getting upstream audaspace fixes for audio files with more than 8
channels.
|

This has already been fixed in 8d207cdc3b307fa20bc5b29059c596306aa2a65c
as fix for T52472: VSE Audio Volume not set immediately, but I failed to
backport it to upstream audaspace which is the reason the problem was
back.

- Silence now has an optional sample rate parameter.
- Fix: wrong length reported by modulator and superpose.
- Minor formatting, include and documentation fixes.

of saved preferences
- Default device (index 0) was hard coded.
- Also fixing crash with invalid device passed to blender via -setaudio.
|
|
- Silence some warnings.
- Fix: Python API memory leak.
- Fix for T54490: VSE breaks when I insert or remove headphones
|
|
Makes building less noisy, helps catching real introduced warnings/errors.
@xeXyon, mind having a look here and possibly apply to upstream? :)

Deleting the old internal audaspace.
Major changes from there are:
- The whole library was refactored to use C++11.
- Many stability and performance improvements.
- Major Python API refactor:
- Most requested: Play self generated sounds using numpy arrays.
- For games: Sound list, random sounds and dynamic music.
- Writing sounds to files.
- Sequencing API.
- Opening sound devices, eg. Jack.
- Ability to choose different OpenAL devices in the user settings.
