David Sutton 52a56f3a52 Audiofiltering: 
Increase efficiency of convolution algorithm.

Approximately 150x faster. (takes ~4.5s to lowpass filter ~1min of audio)
 2022-12-28 16:02:14 +10:30
David Sutton b2d2a41fdc Audiofiltering: 
Add amplification filter which uses filter.Upper as factor for amplification

ausocean-david d029038db9 Audiofiltering: 
Interface the function with pre-existing data structures. The filters can now be generated into a filter type using a generic Generate function.
This generates a filter off of the specifications within the filter struct. There is a generic Apply function which takes in a buffer of PCM data (defined in pcm.go),
and outputs to a []byte.

ausocean-david 75124b4494 Audiofiltering: 
Implement bandpass filter by combining lowpass and highpass filters.

ausocean-david 49db1041d3 Audiofiltering: 
Improve filter performance by reducing frequency leakage.
 2022-12-24 02:28:15 +10:30
ausocean-david fcc7d72b0b Audiofiltering: 
Add highpass filter functionality.
 2022-12-24 02:28:15 +10:30
ausocean-david 8231379a51 Audiofiltering: 
Increase the efficieny and stability of algorithms by making use of waitgroups and goroutines.
 2022-12-24 02:28:15 +10:30
ausocean-david 80ab5e4768 Audiofiltering: 
Create Lowpass filter with frequency control, with efficient convolution algorithm.

Saxon Nelson-Milton 5a07b6ed5f cmd/vidforward: add Makefile and service setup script 
This change provides a Makefile that will build the vidforward
service binary and also utilise a script to setup of a systemd
service for this binary.

Saxon Nelson-Milton 8f8b9ca0f4 cmd/vidforward: add watchdog notifier 
This change adds a "watchdog notifier" utility which tracks the
health of request handlers and notifies an external systemd
watchdog if everything looks good. This allows us to cause a
termination if any request handlers get hung.

Saxon Nelson-Milton 3ea4aff365 cmd/vidforward: restructure code 
This change creates two new files. Firstly, slate.go, to house
slate related functionality. Secondly, utils.go to house generic
utilities and helpers.

Saxon Nelson-Milton f3cf74ce51 cmd/vidforward: add slate image write functionality 
This includes adding facilities to handle termination signals
and err handling. Some modifications have been made to the file
input to accomodate the concurrency requirements. The slate
read mechanism is still fairly rudimentary and can only read
from a hardcoded file, but at this stage is for prototyping
purposes.

Saxon Nelson-Milton a4a9ab07f8 cmd/vidforward/main.go: add control API endpoint with PUT and DELETE methods 
This change removes usage of netsender to provide remote
configuration of the service and replaces with a basic control
REST API with PUT and DELETE methods. PUT requests add or update
a broadcast, and DELETE removes a broadcast. In addition to these
changes, some modification of the NOOP lexer has been performed
including tuning of the controller.

Saxon Nelson-Milton 67e03d0f5c Invert tag for inclusion of CV functionality 
Prior to this change, CV was included by default, however, this
doesn't seem appropriate given that this functionality is rarely
used. For that reason, the meaning of the nocv tag has been
inverted i.e. it is now called withcv, and it the tag must be
included to build CV components.
