Chris@27: Changes in Sonic Annotator 0.4 since the previous release 0.3:
Chris@27: 
Chris@27: Build changes:
Chris@27: 
Chris@27:  - Sonic Annotator now requires the Vamp plugin SDK v2.1 or newer.
Chris@27: 
Chris@27: Front-end changes:
Chris@27: 
Chris@28:  - Frequency-domain plugins now use the PluginInputDomainAdapter's new
Chris@28:  ShiftData processing method, ensuring that the first block received
Chris@28:  by the plugin is the one centred on 0 rather than starting at 0.
Chris@28:  Unfortunately, the old behaviour omitted a timing compensation step,
Chris@28:  and this fix actually changes the results from some plugin processes:
Chris@28:  the previous behaviour was not always in line with the Vamp plugin
Chris@28:  specification.
Chris@28: 
Chris@27:  - More useful diagnostics are now available when a plugin fails to
Chris@28:  load or run.
Chris@27: 
Chris@27: CSV back-end (feature writer) changes:
Chris@27: 
Chris@27:  - The CSV writer now closes its output files properly when it
Chris@27:  finishes writing to each one, rather than leaving them all open
Chris@27:  until the end and risk running out of file descriptors.  This was
Chris@27:  already the behaviour of the RDF writer, the CSV one has just been
Chris@27:  updated to match it.
Chris@27:  - The behaviour of the CSV writer has also been changed to match
Chris@27:  that of the RDF writer in handling file write failures (it now
Chris@27:  continues processing only if --force is given).
Chris@27: 
Chris@27: 
Chris@27: Changes in Sonic Annotator 0.3 since the previous release 0.2:
Chris@23: 
Chris@23: Front-end changes:
Chris@23: 
Chris@23:  - A new --force front-end option (distinct from the --csv-force and
Chris@23:  --rdf-force back-end options) has been added, which makes Sonic
Chris@23:  Annotator continue to process subsequent audio files instead of
Chris@23:  exiting after an error, if multiple audio files have been specified.
Chris@23: 
Chris@23: RDF back-end (feature writer) changes:
Chris@23: 
Chris@23:  - The RDF writer now conforms more correctly with the Music Ontology
Chris@23:  in the way it relates signal, track, and track metadata.  Signals
Chris@23:  that have available metadata now gain a Track resource to associate
Chris@23:  that metadata with, instead of hanging it directly from the Signal
Chris@23:  resource; also the audio file now encodes the signal rather than the
Chris@23:  signal being available as the audio file (matching the domain
Chris@23:  specification of the Music Ontology).  Note that this new resource
Chris@23:  structure will not be properly read by versions of Sonic Visualiser
Chris@23:  prior to 1.6 (should importing the data into Sonic Visualiser be of
Chris@23:  interest to you).
Chris@23: 
Chris@23:  - The --rdf-signal-uri option has been removed and replaced with the
Chris@23:  more meaningful set of options --rdf-audiofile-uri, --rdf-track-uri,
Chris@23:  and --rdf-maker-uri.
Chris@23: 
Chris@23:  - A new --rdf-network option is available, to cause Sonic Annotator
Chris@23:  to try to retrieve RDF descriptions for plugins from the network
Chris@23:  where those descriptions are not available locally.  Use of this
Chris@23:  option is recommended, but it is not the default because of the
Chris@23:  possible performance implication (even though the results are mostly
Chris@23:  cached, there may be some network access involved).
Chris@23: 
Chris@23:  - The RDF writer now writes the computed_by property for signal
Chris@23:  features.
Chris@23: 
Chris@23:  - Plugin and output URIs in the resulting RDF are now percent-encoded.
