TimeStretch history as far as I remember:
AVS 2.60 internal TimeStretch function (forgot the SoundTouch version) only supports stereo audio, multichannel not supported.
Next was the TimeStretch Plugin by Wilbert:
Quote:
changelog:
* version: 2.5.8.0 (requires AviSynth v2.58)
* filter is named to TimeStretchPlugin
* multichannel support
* updated SoundTouch library to 1.8.0
|
This version did support multichannel audio sources.
Then AVS 2.61 Alpha had an even newer internal TimeStretch version:
Quote:
Update to SoundTouch 1.9.0(Wilbert+IanB).
|
For AVS+ the docs are really not very informative. In the AVS Wiki the Timestretch version info says:
Quote:
v2.61 Updated SoundTouch library to 1.9.2. Fixes multichannel issues
|
Since classic AVS was not updated for years I suppose that this info applies to AVS+. But I could not find any info in the AVS+ docs about the current TimeStretch version. And the DLL itself does not have any embedded version info.
