AudioTimeline plugin, thumbsheet script
EDIT 2017/03/10 - new version 0.5.4, small bugfix
The linked plugin displays a audio timeline track under the frame. It is especially suited for thumbsheets, where it allows to estimate the audio track of the thumbnailed clip. The plugin differs from AudioGraph, ViewAudio and waveform plugins as it does not display the waveform (and that in an arbitrarily over- or subsampled manner), but the RMS and peak audio levels, like the HistoGram() function does. Short feature summary Code:
clip AudioTimeline(clip, int "frames" = 1, bool "mixdown" = true, int "height" = 0, int "dBHeadroom" = 6, int "dBRange" = 66, int "loFreq" = 20) - start of the audio time is the current frame (as known from timeline display), window is not symmetrical towards past and future of the frame, but displays the frame and future frames audio - all AviSynth 2.6 pixel formats except YUY2 - 1 display track with mixdown level of all audio tracks or separate display tracks - real level meter representation, level meter height and scale adjustable - adjustable lower frequency limit to avoid display aliasing for low audio frequencies due to too short sample window For completeness, find a thumbsheet function attached. It might deserve an own thread, but the both belong together more or less. The script is undocumented - besides the AudioTimeline plugin, it needs the Cnv2() wrapper posted lately and CallCmd. The plugin of course is documented and comes with source and a test suite. Last edited by martin53; 10th March 2017 at 22:04. Reason: More detailed description of plugin features |
