TNS had both IS and PNS switched on when it makes more sense to have them both off. Prediction had a redundant argument. Signed-off-by:

This commit reorders the coding tools such that they're doing what the decoder does in reverse order. The very first thing the decoder does is to decode M/S stereo if that's signalled, then prediction, IS, and finally TNS and PNS in another function. adjust_frame_information()'s application of IS and M/S was taken out into two separate functions since prediction doesn't expect to get the raw coefficients but rathe the coefficients at that part of the encoding process. The results show a much better PSNR when any combination of Intensity Stereo, Mid/Side stereo and Prediction is used, which is a sign of an increased encoder efficiency as well as the fact that the decoder gets what it expects. Otherwise, with only IS, PNS or prediction there are neither regressions nor improvements except in the case of IS, which now by itself (or with PNS) is less prone to artifacts. Enabling M/S (using stereo_mode) as well will also reduce stereo artifacts induced by IS, so in the very near future M/S may be enabled by default. Signed-off-by:

Since the changes made a few week ago (which were done more than a month ago) the quality and stability of intensity stereo has been notably good. There were some requests and wishes to have in on by default and therefore it has been enabled. Should any regressions arise changes will be made to preferably keep it operating rather than just disabling it by default again. Signed-off-by:

This commit reworks the TNS implementation to a hybrid between what the specifications say, what the decoder does and what's the best thing to do. The filter application function was copied from the decoder and modified such that it applies the inverse AR filter to the coefficients. The LPC coefficients themselves are fed into the same quantization expression that the specifications say should be used however further processing is not done, instead they're converted to the form that the decoder expects them to be in and are sent off to the compute_lpc_coeffs function exactly the way the decoder does. This function does all conversions and will return the exact coefficients that the decoder will generate, which are then applied to the coefficients. Having the exact same coefficients on both the encoder and decoder is a must since otherwise the entire sfb's over which the filter is applied will be attenuated. Despite this major rework, TNS might not work fine on some audio types at very low bitrates (e.g. sub 90kbps) as it can attenuate some coefficients too much. Users are advised to experiment with TNS at higher bitrates if they wish to use this tool or simply wait for the implementation to be improved. Signed-off-by:

This commit adds a function to get the reflection coefficients on floating point samples. It's functionally identical to ff_lpc_calc_ref_coefs() except it works on float samples and will return the global prediction gain. The Welch window implementation which is more optimized works only on int32_t samples so a slower generic expression was used. Signed-off-by:
