Version 5.0-dev-83-g38592252
==
**Enhancements**
* _Convolution Update._ The convolution system is now multithreaded and works on multichannel 48k and 44.1k audio.
* Multiple impulse response (IR) files can now be provided to the convolution system through a new setting: `convolution_ir_files` (the old setting: `convolution_ir_file` is now deprecated). When convolution starts, Shairport Sync will look for an IR file with a sample rate matching the input (44.1k or 48k) and channel count. If an exact match can not be found, it will look for a single-channel IR file with the matching rate. It will always choose the first match in the file list supplied with the `convolution_ir_files` setting or the `D-Bus` method.
* Multithreading of convolution processing is now possible -- use the `convolution_thread_pool_size` setting to set the number of threads to use during convolution. (Note: high levels of multicore operation can cause audible power supply noise on some systems, due to rapid power switching or frequency-ramping of CPU cores.)
* The [HiFi-LoFi FFT convolver](https://github.com/HiFi-LoFi/FFTConvolver) has been updated to the latest available.
* _Loudness Update._ The loudness code now works work multichannel 48k and 44.1k audio.
**Deprecations**
* The Jack audio backend is deprecated and will be removed in the future. It seems to be very little used, and most of its functionality is now available through PipeWire.
**Configuration File and D-Bus Changes**
* A new `convolution_thread_pool_size` configuration file setting has been added, defaulting to 1. This is not available in the `D-Bus` interface.
* The `convolution` setting is deprecated -- use `convolution_enabled` instead.
* The `convolution_max_length` setting is deprecated -- use `convolution_max_length_in_seconds` instead.
* The `convolution_ir_file` setting is deprecated -- use `convolution_ir_files` (i.e. plural!) instead.
* The `loudness` setting is deprecated -- use `loudness_enabled` instead.
* Corresponding `D-Bus` methods and properties have been updated.
**Bug Fix**
* Fix an FFmpeg deprecation warning.
