Bitrate switching quality issue
with 9044ab55 and this bitstream :
ltv_STEREO_48k_sw_13k2_64k.zip
at least between 134 and 143s, we can see the synthesis diverging a lot from the floating point when going from MDCT to DFT
in the figure below, from top to bottom:
- Element_mode
- element_brate
- Left channel float
- Left channel right
- Diff
- Spectrum of the selected part
it happens also between 7s and 17s, but many switching don't show this wrong behaviour
