I think the first step would be to be able to convert a lossy format as MP3 or ogg to a lossless format as FLAC or Wav. Being able to retrieve close in off lost data from lossy compression would be impressive.
- andrewzah 5y agoMP3s generally have a shelf around 16-18khz. The rest of the audible spectrum data is impossible to retrieve if it doesn't exist. This is why transcoding from a lossy->lossless format is a bad idea.
- notagoodidea 5y agoYes, I know and that's what would be more impressive for me to see a ML/Algo that could recreate close enough data distribution from lossy to lossless. Not exact reconstruction but close enough in the possible area (so < 16-18kHz). It may or may not be possible but it is more akin to take the inverse of the model of degradation of MP3 (it could be totally impossible).
