ad062e1879 audioecho: Don't do linear interpolation between samples
Linear interpolation adds quite some noise, and it's unlikely that
anybody will ever need sub-sample accurate delays. Proper resampling
before that will lead to better results.

b68d936ae0 Remove plugin specific static build option
Static and dynamic plugins now have the same interface. The standard
--enable-static/--enable-shared toggle are sufficient.

c32bf052a0 audiofx/echo: added surround-delay and surround-mask
Add a new boolean surround-delay property that makes
audioecho just apply a delay to certain channels to create
a surround effect, rather than an echo on all
channels. This is useful when upmixing from stereo - for example.

Add a surround-mask property to control which channels
are considered surround sound channels when adding a
delay with surround-delay = true

fe2ae2c0f7 scaletempo: Ensure to reinit buffers whenever they were not allocated yet
That is, whenever we go through start/stop we have to ensure that on the
next opportunity the buffers are reallocated again. Otherwise the
buffers might be NULL because the element was reused with the same
configuration as before (i.e. set_caps() wouldn't have reinited the
buffers).

b09f478e80 Add support for Meson as alternative/parallel build system
https://github.com/mesonbuild/meson

With contributions from:

Tim-Philipp Müller <tim@centricular.com>
Jussi Pakkanen <jpakkane@gmail.com> (original port)

Highlights of the features provided are:
* Faster builds on Linux (~40-50% faster)
* The ability to build with MSVC on Windows
* Generate Visual Studio project files
* Generate XCode project files
* Much faster builds on Windows (on-par with Linux)
* Seriously fast configure and building on embedded

... and many more. For more details see:

http://blog.nirbheek.in/2016/07/building-and-developing-gstreamer-using.html

Building with Meson should work on both Linux and Windows, but may
need a few more tweaks on other operating systems.

903c431d6d scaletempo: Free the various buffers in GstBaseTransform::stop()
Previously we leaked them completely, but as they're specific to the caps
freeing them in stop() instead of finalize() makes most sense.

ae3b903019 scaletempo: Fix handling of rate < 0
We have to reverse all samples in a buffer before processing them to properly
have continuous data from one buffer to another. As a result we will have a
negative applied rate and a rate of 1.0.

Also make sure that input buffers are correctly clipped to the segment,
otherwise our calculations are going to go wrong.

Also copy over the segment event's sequence number to the output segment while
we're at it.

42535107ca audiodynamic: assert func_index is inside bounds
Bringing back the check removed in the previous commit but have that check be a
g_assert. Changing the function to static void since return can never be False,
because audio format will never be unkown.

1db92a91de audiodynamic: remove always-true conditional
func_index is set by the sum of three ternary operators which add, 0:4, 0:2,
and 1:0. Minimum value would be 0+0+0=0, and maximum would be 4+2+1=7.
The conditional checking if func_index is >= 0 and < 8 will always be true.
Removing it.
