[Non-BE][split-non-be] Resolve "IGF Stereo TCX noise filling substitution done on the wrong spectra"
requested to merge 931-igf-stereo-tcx-noise-filling-substitution-done-on-the-wrong-spectra into main
- Related issues: #931 (closed)
- Requested reviewers: @reutelhuber
Reason why this change is needed
The IGF decoder in the copy up of source regions replaces lines generated by the TCX core coder noisefilling with newly generated random noise. In the IGF stereo encoder this replacement is done on the wrong source spectra in case of frames with no whitening singalled for IGF.
Description of the change
Apply the TCX noise filling substitution on the correct spectra.
Affected operating points
- Affected are MDCT Stereo and MCT and all modes using either one as transport channel coder.
- Produced bitstream is BE compared to previous state (no encoder change).
