bjorn 19620c7682 wasm: Use default miniaudio buffer size. 
Audio currently stutters on the wasm build.  It is much more severe
in Chrome than in Firefox (very rare/subtle in Firefox).  miniaudio
is currently using ScriptProcessorNode, which is deprecated because
it processes audio on the main thread.  There's a new API that lets
you programmatically process audio on a thread called AudioWorklet,
but it's hella complicated.  miniaudio doesn't want to support this
because it's complicated and requires a separate JavaScript request
but it seems like it would be possible to work around using a Blob.
In the meantime, miniaudio bumps up the buffer size on WebAudio, so
let's just use that in hope that it helps.

bjorn 024498b964 Source:clone fixes; 
Clones no longer try to create converters if they aren't needed, which
was causing an error.

Also handle malloc failure.

bjorn 4469fc99e8 Fix mixer bug; Refactor mixer; 
- Sources without converters always read into the beginning of the
  raw buffer, overwriting previous frames if the source was rewound
  due to looping.  This resulted in an audible click whenever the
  source was rewound.
- After looping, Sources without converters would try to read too
  many frames -- they would read a full buffer instead of only the
  necessary number of frames.

mcc 6b099e467f Encapsulate "uses spatializer?" nature in lovrSourceUsesSpatializer 
Also, remove accessor prototype for old IsSpatial() function
 2021-04-02 14:16:39 -06:00
bjorn 82a309a56d Draft new effects API; 
- A list or map of effects can be provided to newSource.
- false can be used to bypass effects.
- All effects are enabled by default.
  - Occlusion-y effects should only take effect when setGeometry is called
    - Spatializer is responsible for ensuring this.

bjorn cfe0d71520 audio: throw if miniaudio fails to initialize; 
This prevents a situation where miniaudio fails to initialize but the
audio module is still usable.

bjorn c531243d7d phonon: Source:get/setFalloff; 
The falloff is the minimum distance at which inverse distance
attenuation takes place.

A non-positive value disables distance attenuation.

In the Lua API, nil can be used to disable attenuation, a boolean can be
used to enable attenuation with a default minimum distance, or a number
can be used for full control over the parameter.

bjorn 7d0dfc9cdd Sound: Ambisonic support; 
Add support for importing ambisonic WAV files and 24/32 bit PCM WAV files.

The standard ambisonic format used internally in LÖVR is ACN channel ordering with SN3D normalization.
Anything else will be converted to this form.

There are a few restrictions and assumptions:

- Only 1st order ambisonics are supported.  They need to have 4 channels.
- They can be in AMB format (Furse-Malham order/normalization), detected via WAVE_EXTENSIBLE GUID.
- Any other 4 channel file is assumed to be in "AmbiX" ACN/SN3D format.
  - It seems that most ambisonic files in the wild that claim to be AmbiX are just 4 channel WAVs without any metadata.
  - This means that non-ambisonic 4 channel WAVs could ambiguously be mistaken as ambisonic.  This is incurred as a limitation of LÖVR.
- Ambisonic files can not currently be played back.  SteamAudio currently has numerous bugs with this.
  - Perhaps it would be possible to write an ambisonic rotator/panning decoder to use as a default implementation.
