./audio/vamp-plugin-sdk, The Vamp audio analysis plugin system

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]


Branch: CURRENT, Version: 2.9.0, Package name: vamp-plugin-sdk-2.9.0, Maintainer: pkgsrc-users

Vamp is an audio processing plugin system for plugins that extract descriptive
information from audio typically referred to as audio analysis plugins or
audio feature extraction plugins.

Just like an audio effects plugin (such as a VST), a Vamp plugin is a binary
module that can be loaded up by a host application and fed audio data. However,
unlike an effects plugin, a Vamp plugin generates not more audio, but some sort
of symbolic information. Typical things that a Vamp plugin might calculate
include the locations of moments such as note onset times, visualisable
representations of the audio such as spectrograms, or curve data such as power
or fundamental frequency.

vamp-plugin-sdk: Update to 2.9.0

Version 2.9, 2019-11-13 (maintenance release)

  * Fix non-thread-safe behaviour in PluginAdapter. Plugins built
    using the adapter classes in version 2.8 or earlier cannot safely
    be used simultaneously across threads with other instances of
    themselves or of other plugins in the same library (i.e. shared
    object). Hosts have been required to provide synchronisation for
    such cases. Version 2.9 introduces synchronisation in the plugin,
    making this usage safe. Unfortunately this does not make host code
    safe when using older plugin builds, as the problem and its fix
    are in the plugin side of the SDK. Caution is still required, but
    this fix does allow updated plugin builds to avoid problems with
    some existing hosts
  * Change required C++ language standard from C++98 to C++11. This
    is because of the use of std::mutex in the above fix

Log message:
vamp-plugin-sdk: Update to 2.8.0

Version 2.8, 2019-02-07 (maintenance and minor feature release)

  * When running in a 32-bit process within 64-bit Windows (WoW64),
    use the VAMP_PATH_32 environment variable instead of VAMP_PATH
    (hosts running in this context already use "Program Files (x86)"
    instead of Program Files)
  * Fix off-by-one rounding errors in frame-to-ns conversions. Unlike
    the other changes here which are invisible to plugin code, this
    change can lead to different results in the lowest significant
    figures from existing plugins if relinked against the newer code
  * Fix path environment variable character encoding handling on
    Windows
  * Fix theoretical possibility of integer overflow in RealTime
    constructor
  * Fix use of undefined behaviour in PluginRateExtractor

Version 2.7.1, 2017-03-06 (maintenance release)

  * Fix inclusion mechanism for FFTs which could cause a host
    application to crash in certain circumstances due to
    conflicting versions of C-linkage symbols

Version 2.7, 2017-02-24 (maintenance and minor feature release)

  * Add ability to PluginLoader to list plugins only in (or not in)
    certain library files
  * Fix fixed-sample-rate output timestamps in printout from the
    simple host, and add regression test script using test plugin
  * Switch the convenience FFT interface for plugin usage from the
    very slow reference implementation previously provided, to the
    somewhat faster KissFFT
  * Add a top-secret compiler flag to switch internal FFTs to single-
    precision only
  * Fix some small but long-standing memory leaks and minor bugs
