Hi all... Can anyone help me? I'm interested in ITU-T recommendation G.722.1(not SB-ADPCM) using MLT (Modulated Lapped Transform)... But I can't find materials about it. (ex) algorithm description, source, etc. Bye... Have a good day... |

You can get it at their online bookshop. Last time I looked it was still a draft standard. They have a free promotion just now so you can probably get the documents you need for free. 722.1 was originally designed by a friend of mine, and I've been programming it on a TI c55, so if you have any specific questions I might be able to help. (Ask on the list in case there is any general interest or anyone knows better than I do). I have a short list of possible errata for the C code and have been waiting for the official list to compare with mine, but when I last checked it was still "to be published". Does anyone here know who might be in charge of this document? (My old colleague moved on from PictureTel).
