Hi I am student working on a school project to implement MS stereo on dist10 code. I am new to mp3. I tried MS sparsing based on ISO 11172-3 which does not seem to work too well. I had KIV it. Now, I am trying to implement it using the ISO 13818-7 MS stereo part. I am not very sure how to implement the algorithm on mp3.
Here is my algorithm: 1. Calculate and store nb(b) and en(b) for L/R and M/S as in calculate threshold(part 1). However when calculating M/S threshold, do we use the minimum c(w) values from L/R. Is that the tonality index for L/R? 2. Using the raw threshold and energies from M/S and L/R, calculate bmax and all final thresholds. 3. Are the final threshold used to calculate the pre-echos controls? As in the nb(b) in step 11 as stated in the standards? 4. We now have 4 finals threshold ie L/R and M/S. Which ones do we use to calculate the ratios in l3psy.c in mp3?
