2019-08-24Mitigate issues of expensive plugin analysis -- #7795Robin Gareus
Plugin analysis uses a GUI thread instance of a given plugin to perform a IR analysis. Some plugins can be rather CPU expensive to analyze. e.g. a-hi/lo-filter when interpolating is recalculating biquad coefficients every 64samples during the 8k IR analysis. This can take a significant amount of time on older CPUs. Furthermore live-signal collection happens in the rt-thread, using cross-thread signals. Signal collection is periodically initiated from the same timeout signal as analysis. Analysis is was done using default thread priority, which is higher than the GUI redraw priority (PRIORITY_HIGH_IDLE). So it was possible to contiguously initiate analysis, loading the CPU and preventing redraws.

Copyright-holder and year information is extracted from git log. git history begins in 2005. So (C) from 1998..2005 is lost. Also some (C) assignment of commits where the committer didn't use --author.
2019-07-17FFT analysis: use actual latencyRobin Gareus
Ardour allows to override a plugin's reported latency. So far this was not taken into account when plotting the phase/freq response.

2019-02-28Re-work plugin-analysis (fix crashes)Robin Gareus
Plugin-analysis uses a fixed number of samples, which may be larger than the session's block-size. This caused problems for some VST plugins that use audioMasterCallback to query the session's block-size. Plugin FFT analysis now processes in chunks of the session's block-size to avoid this issue. This also allows to increase accuracy for all plugin standards (FFT size was increased to 8192).

Show vertical marker-line (freq) and precise numeric data of the transfer function (dB, deg).

2018-04-13Fix plugin analysis for some VST and AU Plugins.Robin Gareus
set_block_size() implies plugin deactivate(), activate() calls to re-initialize AU and VST plugins. So plugins will reset the internal state and not immediately respond correctly. Some plugins zero the output or ramp up internally, leading the analyzer to show invalid or random/uncorrelated information. This avoid periodic calls to de/activate()

When freq was changed to be an integer, the conversion to kHz became a truncation. Divide by the float 1000.0 to pass the correct value to the stringstream formatting routine.
