#62Novel, but until it's open source, it will never be taken seriously.
Re: New Ultra Fast Lossless Audio Codec (HALAC)
#63Tip for those who are looking at the compression ratios thinking "so what?": look at the run-times. It's a minimum of 3x faster than its contemporaries.
IMHO that's still a "so what?". I see audio compression as having two primary purposes: realtime and archival, and speed is only vaguely relevant for the former. In realtime applications, any processor within the last decade is far more than powerful enough to encode and decode in realtime. The first set of tracks in the results is 2862s long and even the slowest WAVPACK manages to encode it in >113x realtime and clo…

In this regard, you can review the HALIC link if you want. https://encode.su/threads/4025-HALIC-(High-Availability-Loss...
Oh well.

#65Earlier quoted context omitted.
Saving a small fraction of a second millions of times over, or a handful of cycles a trillion times over, is so much more impactful than saving a dozen seconds per hour-long recording. Also your link doesn't explain what they changed?

At a large-enough scale, all savings are significant. > Also your link doesn't explain what they changed? They changed a function signature to use an output argument instead of a return value. i don't recall the exact signature, but…
Yes, but not every tradeoff between compression speed and compression ratio is something that makes sense to scale in the first place.

Tell us more about "I don't aee anything suspicious". How exactly do you know it's not a binary that hashes all your files using a key and asks for btc to revert?
Open in hex/text editor, scroll through and look for anything suspicious like network, crypto, obfuscated sections (major red flag), strange strings, etc. The #1 most reliable sign of malware is if it's unusually large and packed/obfuscated, but this isn't. The guy even has his full name and contact info in there. This is harmless. If you don't trust me you could upload to an online malware multiscanner (which tends…

#67What interests me the most is the memory usage.

It's not about whether this particular announcement, with these particular executables, is trustworthy or not. It's about the whole process of regularly downloading and running executables uploaded by individuals to a BBS-type forum being unimaginable in most other parts of the software world, and violating every security "best practice" written about in the past 30 years. I know that this is how things were once don…
The vast majority of the world still downloads and runs executables uploaded by individuals, albeit perhaps not on a bulletin board or forum (most of those have been killed and replaced by social media).

#69Yall should really have a look at his lossless image format. That has a spectacular compression:speed ratio. https://encode.su/threads/4025-HALIC-(High-Availability-Loss... What interests me the most is the memory usage.

#70I love how some announcements of developments still occur in good old-fashioned forums; it really warms my heart to see that. Kudos to the author for the hard work!
