-/**
- * SECTION:element-scaletempo
- *
- * 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 \
- * d. ! queue ! videoconvert ! autovideosink
- * ]|
- * 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.
