* Scale tempo while maintaining pitch
|
||||
* (WSOLA-like technique with cross correlation)
|
||||
* Inspired by SoundTouch library by Olli Parviainen
|
||||
*
|
||||
* Use Sceletempo to apply playback rates without the chipmunk effect.
|
||||
*

||||
* <refsect2>

||||
* <title>Example pipelines</title>
|
||||
* <para>
|
||||
* |[
|
||||
* filesrc location=media.ext ! decodebin name=d \
|
||||
* d. ! queue ! audioconvert ! audioresample ! scaletempo ! audioconvert ! audioresample ! autoaudiosink \
|

* OR

* |[

* playbin uri=... audio_sink="scaletempo ! audioconvert ! audioresample ! autoaudiosink"
|
||||
* ]|
|
||||
* When an application sends a seek event with rate != 1.0, Scaletempo applies
|
||||
* the rate change by scaling the tempo without scaling the pitch.
|
||||
*
|
||||
* Scaletempo works by producing audio in constant sized chunks
|
||||
* (#GstScaletempo:stride) but consuming chunks proportional to the playback
|
||||
* rate.
|
||||
*
|
||||
* Scaletempo then smooths the output by blending the end of one stride with
|
||||
* the next (#GstScaletempo:overlap).
|
||||
*
|
||||
* Scaletempo smooths the overlap further by searching within the input buffer
|
||||
* for the best overlap position. Scaletempo uses a statistical cross
|
||||
* correlation (roughly a dot-product). Scaletempo consumes most of its CPU
|
||||
* cycles here. One can use the #GstScaletempo:search propery to tune how far
|
||||
* the algoritm looks.
