I just produced a new version of the decoder. It can do some amazing things, needed because lots of material (mostly before 1990s) has been distributed with DolbyA encoding still intact. That leaves a harsh, compressed HF, sheen, overly crisp voices -- kind of sound on the recording. My decoder, does a very credible job of a true correction, and is being used professionally as a DolbyA decoder. It was compared with a true DolbyA unit (actually several of them) and another software decoder. This software came out significantly closer to the results of a true DolbyA decode than the other SW.
The program is not a trivial little toy, but does lots of work to both clean up the audio and to clean up the intermodulation and other evils that occur oh so easily when doing nonlinear processing on audio. I have posted the program da-win-06may2018A.zip, a file containing some hints: DecoderA.pdf, and some EYE-OPENING example recordings. Repo location: https://spaces.high…
The decoder is free, has no timeouts or anything like that. It works only on recent Intel or AMD machines -- the da-win version will work on newer ATOMS like the Silvermont (and will work on the newest CPUS but doesn't take advantage of them.) the da-avx version takes better advantage of the more advanced vector operations. 95% of the CPU usage on this program is vector math -- fairly advanced code. It is MUCH more processing than a simple DolbyA emulator because it has to sound GOOD. Simple implementations will have so much intermod, people will say things like: there is that harsh computer processor sound again. This code is less distorting by far than even a real DolbyA.
The updated DolbyA compatible decoder introduces enhanced audio fidelity, ensuring a richer listening experience. Its advanced features promise to elevate sound quality, making it an indispensable tool for audiophiles and professionals alike.
AI is becoming really good, isnt it? I can’t quite see this response making any sense, because lots of the old files have expired now, and the topic got resurrected?
yup, the fake world is upon us, Paul. Google bots have been harvesting content for years and now they are going to sell it all back to us. Fake people, fake meat, fake money, fake music, fake news etc etc for all the useless eaters to google over it all.
I must say I’m a fan of the technology, but not of the purposes it gets put to, but I have found one really good thing it’s great for. Adobe photoshop can add things to images and generate new stuff and it does it really well. Best thing is that the copyright status, at least at the moment, is good. I’ve been using it to generate cover images for my music. The music is the easy bit, but I really struggle with lack of talent in the art department. My music is very suitable for computer generated art, and I have been producing the images with a fractal based app for years now which works for the majority, but others, are scenery pictures I have taken myself. Rivers, lakes, buildings, scenery etc. but now I can take a picture and add a church or a tree or bizarre things. This AI example is positive, but joining this site and posting waffle? What is the point?
