Mike Brady 60143518c2 This squashed commit comprises a long series of improvements, bug fixes, optimizations, and new feature additions: 
- 48,000 frames per second operation,
 - 48k lossless stereo, 5.1 and 7.1 surround sound
 - Multichannel and multi rate operation on ALSA, PipeWire, PulseAudio, FreeBSD, stdout and unix pipe output backends.

Automatic, flexible and controllable output format (rate, sample format and channel count) selection.

Full FFmpeg integration to support transcoding, resampling, and new audio formats.

Better operation on lower powered devices down to e.g. Raspberry Pi B.

Reduced Docker image sizes with a slimmed-down FFmpeg library.

Enhanced timestamp handling for better synchronization.

Improved the sync error calculation.

A new "vernier" resampling and interpolation method for low-power CPUs.

Bug fixes and minor enhancements.

Note -- there are many breaking changes from previous versions of Shairport Sync!

Chris Boot b9cf91b2bb More typo fixes across the tree 
Previously I have made spelling changes as caught by Debian's lintian
tool, which has a short list of common misspellings that it tests for.
This time I decided to run codespell against the source and fix all the
obvious problems it came up with. It also uses a list of misspellings
but it's much larger than lintian's, but also has some false positives
so I went over the list by hand.

The command I used to do check the source was:
git ls-tree -rz --name-only HEAD | xargs -0 codespell -L minimise,errorstring
 2019-07-27 00:05:38 -03:00
Mike Brady a8faacd3fc Expose some of the settings used in the disable_standby_mode. 
Specifically, firstly, the disable_standby_mode_silence_threshold, which is the
amount of audio in the output device's hardware buffer. It should normally
be close to the value givein in the audio_backend_buffer_desired_length_in_seconds
setting. If it drops to this value, silence is added to the buffer to prevent
the output device from becoming idle.

Secondly, the disable_standby_mode_silence_scan_interval is the time between checks
of the output device's hardware buffer.

The code for generating frames of possibly-dithered silence has been simplified.
